When starting to calculate the number of tiles, you should decide on the type of installation, color scheme, the need for adjustment to the drawing, the use of additional decorative elements, finishing area.
Popular types of floor tile installation:
- standard. The material is located along the walls;
- diagonal. The tiles are laid at an angle of 45°C.
- diagonal chess. This installation method uses ceramics different colors, while alternating tiles occurs.
Types of laying wall material:
- straight. The elements begin to be laid parallel to the floor.
- straight with curbs. A narrow or wide border can be used.
- checkerboard (diagonal or normal direction).
- diagonal.
How to calculate tiles for a bathroom? First of all, you should choose the type of installation. This will allow you to correctly determine the material consumption (for example, when laying diagonally, numerous tile trims are made; when fitting according to a pattern, the edges of the tiles are trimmed).
General rules for calculating tiles:
- Measure the width and length of the walls of the room that will be used for finishing, and also take the dimensions of the floor. Subtract the area of the door (bath) from the area of the wall in which the door is located or the bathtub is installed.
- Check the tile dimensions. For the floor it can be tiles 30*30, 40*40, etc., for walls - 20-30, 25-33, etc.
- Calculate the area of the cladding (in square meters).
- Divide S of the surface by S of one tile and get the amount of material in pieces.
- Add 5% to the resulting number (reserve for trimming material).
- Method I
Tile laying will be done in a standard way tiles measuring 33*33 cm. Find the number of tiles in one row - divide 150 cm (width) by 33 (the length of the side of the tile) and get 4.54 (the number of tiles in one row in width). After rounding we get 5 pieces. With a floor length of 170 cm, we find the number of rows - divide 170 by 33 and add 1 piece for reserve. We multiply the resulting quantity by the number of tiles in one row and get the result - 31 pieces.
- II method
If we counted ceramics not individually, but by floor area, the error would be quite significant. Surface area 1.7m*1.5m=2.55 m2. Tile area 0.33*0.33=0.11 m2. We divide one value by another and get 24 pieces (with rounding), add a margin of 5% - 2 pieces and we get 26 pieces. As a result, we would be 5 tiles short. When counting piece by piece, we took into account the trimming of the plates that will be done during installation.
Calculation of tiles for bath walls
To calculate, we need the width, length and height of the walls. For example, the dimensions of the ceramics are 20*30 cm, while the border is 8*20 cm. The height of the room is 2.7 m. We determine the number of tiles for each wall separately and sum up the resulting numbers.
You can simplify the calculation if you first calculate the perimeter of the room. Then the width of the door (0.6 m) should be subtracted from it. As a result, we get – (1.5+1.7)*2-0.6==6.3. In our example, the bottom of the walls will be lined with dark-colored ceramics, the top will be light-colored, and the border will be between them. We divide the height of the walls into 3 sectors and get 2.7-0.08 (border) = 2.62 m, while the height of the bottom will be 1 m, the light top will have a height of 1.62 m.
We calculate the amount of dark tiles as follows: 6.3*1=6.3 m2. Considering that the area of 1 tile is 0.3*0.2=0.06 m2, we determine the quantity - 6.3/0.06=105 pieces. We increase by 5% and get 110 pieces.
We find the amount of light tiles in a similar way: 6.3 * 1.62 and we get 10.206 m 2. We divide 10.206 by the tile area of 0.06 and get 170.1 pieces. We add 5% to the stock, and in the end we get 179 pieces. We determine the amount of tiles that will be used for laying above the door 0.6 * 0.7 = 0.42 m 2. We divide the resulting value by 0.06 (S tiles) and get the quantity of 7 pieces. Total: 186 units of light tiles.
We calculate the border as follows: 6.3/2 = 31.5. We round the resulting figure to 32 pieces.
How to calculate tiles for a non-standard installation option?
Often, to create exclusive interiors, complex masonry methods are used - “herringbone”, “staggered”, etc. In order to correctly determine the amount of material, you should display on a sheet of paper (millimeter or squared) on a convenient scale the area that will be processed. Taking into account the scale, draw a diagram of the masonry, marking solid elements and those that will be trimmed with different icons. This will allow you to calculate the tiles for the bath as accurately as possible. Once the amount is determined, increase it by 10%.
Calculating the amount of glue and grout
The amount of glue required for laying ceramics depends on factors such as the smoothness and condition of the wall and floor surfaces, the thickness of the adhesive layer, and the size of the tiles used. The smoother the walls are, the lower the glue consumption. The larger the surface of the tile, the more glue is applied. For average plastered walls, you can calculate the amount of glue based on the information provided by the supplier on bags with the composition.
At the final stage of laying the tiles, we grout the seams. For these purposes, a special composition (grout) is purchased that matches the tone of the main color of the coating; a contrasting option is also possible (for example, white grout is matched to black tiles).
To calculate the amount of grout, you need to determine the volume of space that needs to be filled. The depth of the seam is equal to the thickness of the tile multiplied by 1.5 (taking into account the shrinkage of the material), the width of the seam can vary between 1.5-3 mm. The amount of grout is calculated as follows: 1/2 the perimeter of 1 tile should be divided by its area and multiplied by the thickness. We multiply the resulting result by 1.5. As a result, we get the mass of grout in kg required to lay 1 square meter of ceramics.
Example, the joint width is 2 mm, while the area of 1 tile is 0.04 m2. For 3.5 m2, 1 kg of grout is enough.
Getting started with repairs and installation flooring, many home craftsmen are faced with the problem of how to calculate how many tiles are needed for the floor. When determining the amount of tiles, which is a popular facing material for utility rooms, some nuances should be taken into account.
Features of calculations
There are certain rules for how to calculate floor tiles. To update a room, you need to know exactly the amount of finishing material.
In practice, several options are used to perform the calculation floor tiles, but they all have general features, which are related to the specifics of execution installation work And distinctive characteristics tiles
When making calculations, the following nuances should be taken into account:
Calculation of tiles taking into account the area of the room
There are several methods for calculating how many tiles are needed for the floor. The easiest way is to use the ratio between the area of one element and the entire area of the floor surface. But this method used only if it is planned to install seam to seam.
- the room is measured along the perimeter;
- take the largest value of length and width;
- both quantities are multiplied and the square footage of the room is found out;
- calculate the area of one tile by multiplying its length and width;
- divide the square footage of the room by the area of one product;
- 10% of the total number of tiles is added to the result obtained for the margin, and 15% is added for diagonal laying.
To calculate the surplus, similar calculations are performed regarding areas of the floor surface that are not planned to be tiled. Read also: " Optimal thickness ceramic tiles for gender - what is it like?
Calculation of tiles by the number of tile rows
According to experts, there is a more accurate way to calculate the number of tiles on the floor, based on calculating the number of rows. In this case, the number of tiles in each of them should be rounded up, since a fractional number means the use of cut fragments.
The sequence of calculating tiles relative to the number of rows:
This calculation method gives a more accurate result, since in this case the number of non-integer fragments is taken into account. The difference between the first and second methods is sometimes 10-15 tiles, which is an important nuance when installing tiles.
Number of tiles when laying diagonally
The two calculation methods described above are used when laying out tiles according to standard patterns. The problem of how to calculate the tiles for the floor when they are placed diagonally can be solved by drawing up a diagram for laying the floor covering. In a word, the number of elements should be counted one by one. Read also: “How long does it take for floor tiles to dry after installation.”
To do this, take a sheet of paper, preferably millimeter paper. You need to transfer the exact parameters of the room onto it, respecting the scale. They also indicate the boundaries of the area that is planned to be covered.
Then they determine how much space one tile occupies on the diagram. Then they begin to draw each element according to the installation method in the direction of installation. In the figure, both whole tiles and partial fragments are indicated and then the required amount of materials is calculated.
Computer programs for calculating tiles
When it is not possible to calculate floor tiles manually or there are doubts about the correctness of the result obtained, you can use specially designed computer programs, which allow you to count the number of facing elements in a matter of minutes.
Despite the large number online calculators on the Internet, experts do not recommend trusting them too much, since these programs do not take into account all the nuances of future tile installation.
To calculate as accurately as possible required amount material, you need to use specialized software with limited functions. Since in order to take advantage of their full option, you need to purchase a licensed product, which is quite expensive, in this case it would be best to contact a professional in the field of design and engineering or for advice from a hardware store salesperson.
Specialized retail chains often provide the service of counting the number of tiles free of charge. In this case, it will be possible to choose the optimal option for laying tiles, both according to standard patterns and diagonally (for more details: “Laying tiles on the floor diagonally - how to do it correctly”). As a result, you will be able to find out the number of whole and cut elements.
The result depends on the correctness of the floor covering calculations. repair work. If a mistake is made and there is not enough material, there is a high probability that you will not be able to purchase the missing amount of the desired color or design.

Correct calculation of the need for floor tiles
In our time, high-quality tiles have ceased to be a scarce finishing material, and floor coverings are not done so often that ceramics can be purchased for future use in large quantities. Therefore, calculate the consumption facing material need to be done correctly, taking into account the specifics of the technology and production capabilities spot repair floor covering.
Correct is the calculation of flow rate with a minimum error, and only in a larger direction. This will save money and eliminate unpleasant surprises when there is not enough material and you need to at least buy more.
Despite its apparent simplicity, the calculation of the need for ceramics must be made taking into account many factors that influence the consumption of tiles:
- size and configuration of the room;
- type of flooring (straight, offset, diagonal);
- tile format.
The length and width of the room are measured with a tape measure
Determination of tile consumption in square meters
Monotonous floor finishing with ceramic tiles using direct laying, diagonal laying or offset tiling is a common technology. Calculating the need for tiles in this situation begins with measuring the floor with a tape measure and calculating its area by multiplying the length in meters by the width.
6.3 m x 3.1 m = 19.53 sq. m.
To calculate in square meters the number of tiles required to finish this area, you need to add 10% to the resulting value and round the result up, taking into account the trimming of products during the gluing process and possible damage to the material.
Floor tile packaging
19, 53 sq. m. x 1, 1 = 21, 483 sq. m. We round up and get 22 sq. m. tiles
The packaging with ceramics indicates how many square meters of material are contained in a box of tiles, for example, 1.1 square meters. Dividing our obtained consumption value by this value, we get how many packs are required:
22. 1, 1 = 20 packs - the final result of calculating the need for tiles. If the value is fractional, then the number of packages must be rounded up to whole units.
Counting when laying diagonally
Sticking tiles diagonally allows you to hide defects in the geometry of the room, which justifies a slightly higher consumption of ceramics when using this type of flooring.
When laying tiles diagonally, 15% must be added to the floor area, since adjusting the ceramics when fastening in this way creates more substandard waste, and the result is also rounded up.
19, 53 sq. m. x 1.15 = 22.46 sq. m.
After rounding we get 23 sq. m. facing material, divide by the square footage of the ceramics in the box and get the amount of tiles expressed in packs:
23 sq. m. 1, 1 sq.m. = 20.9 packs. We round up and get how many tiles you need to purchase - 21 boxes.
If the room has a different shape (trapezoid, polygon, oval, circle), then the area of these figures is determined using the appropriate mathematical formulas, or the floor is divided into simple geometric components (rectangles, triangles), the area of which must be calculated separately and summed, and then, taking into account the type of flooring, apply an increasing factor of 1.1 or 1.15.
When laying tiles diagonally, the calculation is made in the same order as with conventional
Piece method for determining flow
This calculation of the need for material gives less error and is used mainly when using expensive finishing materials by direct laying method or when creating an artistic panel on the floor. When laying ceramics diagonally, this calculation method is not applicable.
Let's look at the calculation using a specific example.
Room dimensions: 6.3 m x 3.1 m.
Product dimensions: 0.25 m x 0.20 m.
At direct way When laying ceramics across a room, the length of the room will fit the following number of sheets of ceramics:
6.3 m. 0.2 m = 31.5 pieces. Round up and get 32 pieces.
The width of the room will fit:
3.1 m. 0.25 m = 12.4 pieces. After rounding we get 13 pieces.
We multiply these values and get:
416.10 = 41.6 packs. Round up and we get 42 packs of tiles.
Experts say that piece-by-piece calculation of tiles is more accurate.
Combined demand calculation
In this case, a sketch map of the floor finish is drawn up, measurements are taken of individual sections of the base and the format of the corresponding tile.
At first piece by piece method the amount of ceramics involved in the composition of the panel or ornament in the center of the room is calculated, and then, in square meters or also individually, you need to calculate how many sheets will be needed to decorate the background areas with monotonous cladding, taking into account the difference in waste between direct laying and diagonal laying.
Using these recommendations, you can minimize the likelihood of errors in calculating the need for ceramics and save not only on minimum quantity the remaining material, but also on the absence of the need for additional trips to purchase tiles in case of shortage.
Calculating the number of tiles on the floor: features and methods of calculation
At the very beginning of the renovation, you will inevitably face the question of how to calculate the tiles for the floor. Since tiles are one of the most popular types of facing materials for the bathroom, kitchen and hallway, you should definitely familiarize yourself with the rules for making calculations.
When calculating the number of tiles per floor, it is necessary to take into account a number of nuances
Features of calculations
No matter how much you would like to, it is impossible to estimate by eye how many materials you will need in order to update the room. There are several ways to calculate how many tiles are needed for the floor, but they all share some features related to the specifics of the work and the properties of the material itself.
Features of calculations:
- To calculate how many tiles you need, you should take into account not only the area of the room, but also the size of the tiles.
- Keep in mind that you will have to use not only whole elements, but also trim some areas.
- If the floor is not tiled under the bathtub or furniture, subtract the excess amount.
- The type of layout plays an important role. Laying offset or diagonally will require more tiles than straight laying.
- Always add a small percentage for reserve, since during the installation process it becomes necessary to trim some elements, and there is also a risk of defects in the batch, fragments with differences in color or damage during work.
In the calculations, it is necessary to take into account the presence of trim elements
Please note: when making calculations both straight and diagonal, it is necessary to take into account how many tiles are needed to cover the ledges and borders.
By room area
There are several ways to calculate the required number of tiles for the floor. The simplest is to correlate the area of one piece of tile to the area of the room. However, it is worth considering that it makes sense to use this approach only when simple seam-to-seam laying is used.
Calculation method in the first way:
The correct calculation of tiles depends on the accuracy of measurements of the working surface area
By number of rows
How else can you calculate how many tiles you need for the floor? The best option is to use a method that is based on determining the number of rows. The number of tiles in each of them must be rounded up, since a fraction means the presence of cut fragments.
This method is more accurate, since it indirectly takes into account the number of threaded elements. The difference in results between the first and second approaches can be on average about 10-15 tiles, which in fact is a very significant shortcoming.
Calculation of tiles by rows
Schematically
Both methods are more suitable for a standard layout scheme, now let's look at how to calculate tiles for the floor when installing diagonally? This problem can be solved by developing a flooring scheme. In other words, the number of tiles must be counted in the literal sense of the word.
Graph paper is most suitable for this task. Transfer the exact dimensions of the room to scale onto it and mark the boundaries of the area to be covered. Then determine how much one tile should occupy in the drawing and begin to draw it according to the diagram (straight, diagonally, staggered) and the direction of laying. Mark the whole and cut elements, and then calculate the required number of tiles.
Computer program
A special program will allow you to quickly calculate the amount of facing material
On the Internet you can find various manuals and online calculators for calculating the number of tiles, but you should not trust such programs, since they do not take into account the specific factors of future masonry.
In order to more or less correctly calculate the consumption of materials, specialized design programs are used. You can find trial versions of such products on the Internet, with limited functions. Since spending money on purchasing a licensed full version is impractical, it is best to seek help from a designer or a construction store consultant. In elite salons you will definitely be provided with a counting service. In this case, it will be possible to determine how many whole and cut fragments are needed with an optimal laying pattern, both straight and diagonal.
The fate of your repair depends on how correctly you determine the amount of tiles. If you make a mistake and buy more than you need, it’s not a problem, because the leftovers can still be useful in the future. But if there is a shortage, you risk facing a situation where you will not be able to find a suitable tile to purchase the missing quantity.
04-04-2015Before you start installation tiles on the floor or start decorating the walls, you need to determine in advance the required amount of tiles. Only by thoroughly understanding how to calculate the number of tiles and performing the appropriate calculations can you avoid extra costs and reduce waste to a minimum.
You need to buy tiles 10% more than the required volume for cladding.
What should be taken into account during the calculation?
- decide what type of tile installation you will choose;
- decide on the color scheme;
- decide whether it will be necessary to adjust the tile according to the pattern;
- decide whether the walls will be covered only with ceramic tiles or whether the finishing will be supplemented various kinds decorative elements.
There are several ways to lay tiles. You need to choose one of them and based on decision taken calculate the number of tiles. The floor can be covered in one of the following ways:
- Standard – in in this case the edges of ceramic products are mounted along the walls.
- Diagonal - the edges are laid at an angle of 45 degrees.
- Diagonally checkerboard - laying tiles different color with alternation.
For wall cladding, you can choose one of the following methods:
- The usual straight line - the elements are laid parallel to the floor surface.
- Regular with borders (you can use 1 wide border or alternate narrow with wide).
- Checkerboard (tiles can be laid both in the usual direction and diagonally).
- Diagonal.
It is very important to choose the type of installation before calculating the number of tiles. Take into account the fact that if ceramic tiles are laid diagonally, the consumption of finishing material will increase significantly, because you will be forced to trim products to fit from the center of the room to the corners. If it becomes necessary to make adjustments to the pattern, the number of tiles required for cladding will also increase. Do not forget that the joints of the first rows should be made away from the walls. This will visually hide the unevenness of the partitions.

There are a number general rules, according to which you can determine the required number of tiles for the kitchen, bathroom and any other premises.
You will need the following tools:
- roulette;
- calculator;
- paper;
- pencil or pen.
Take a tape measure and measure the height and length of the surfaces you are going to cover. ceramic tiles. After this, measure the width and length of the floor. Record the resulting values in centimeters. From the dimensions of the wall with the doorway, and if the tiles will be laid in the bathroom, then from the one in which the bathtub is installed, it is necessary to subtract the dimensions of the opening and the bathtub.
Next, you will need to decide on the size of the tiles you will be laying. To finish the floor, tiles measuring 30x30, 33x33 cm, etc. are used. The walls, as a rule, are finished with smaller tiles - 20x30, 25x33 cm, etc. Pre-calculate the result in square meters, and then count the number of tiles individually. It is necessary to add about 10-15% to the calculated value. During the installation process, you will have to trim the tiles; some products may be accidentally damaged or turn out to be defective, so such a reserve must be made.
No matter how perfect such programs are, they still allow some errors. For example, such applications do not take into account the width of the seams, and the developers themselves still recommend double-checking the results.

Example of calculation of floor tiles
To determine the number of tiles needed for a floor, measure the width and length of the surface, as well as the size of the tile itself. In this example, we will consider the calculation for a room with a floor of 150x170 cm, for the finishing of which ceramic tiles measuring 33x33 cm will be used.
First, divide the width of the floor by the tile side. It turns out that for laying in 1 row in width you will need 4.54 tiles. The resulting value must be rounded to 5. Calculate how many such rows there will be in your room. To do this, divide the length of the room by 33 cm. The result will be 5.15 rows. Round up to 6. Now multiply 5 ceramic tiles in a row by 6 rows. You will get 30 pieces, to which you need to add at least 2-3 tiles in reserve. So you will need to buy 33 tiles.
If you were to perform a calculation based on surface area rather than per piece, you would make a rather significant mistake. The floor area in the room in question is 2.55 m². The area of one tile used is 0.11 m². If you were to use this data, the result of the calculation would indicate the need to use 24 tiles (rounded up). That is, in the end you would not have enough material to work with. And the whole point is that when performing a piece calculation, the cutting of the tiles during laying is taken into account.

Example of wall tile calculation
As an example, we will consider a room whose wall height is 270 cm, width is 150 cm, and a 30x20 cm slab is used for cladding. Divide the height of the surface by the height of the tile. It turns out that there will be 9 ceramic tiles in the 1st row in height. Divide the width of the surface by the width of the tile. The result is 7.5, round to 8. Now multiply 9x8. In total, you will need to purchase 72 tiles. Add 7-10 tiles in reserve.
To calculate the number of tiles for finishing a wall with a doorway, take the calculation data determined for the opposite wall and subtract from given value the number of tiles per doorway. For example, a doorway is 200 cm high and 70 cm wide. The same 30x20 cm tiles are used for cladding. Divide the height of the opening by the height of the tiles. The result will be 6.7. In this case, it is necessary to round down, i.e. to 6. Divide the width of the opening by the width of the tile. The result is 3.5, round to 3. Multiply 3 by 6. As a result, to finish the partition with the doorway you will need to take 18 fewer tiles. A similar calculation must be performed for the surface on which the bathtub is installed, if you do not plan to tile the space that the container occupies.
This question is one of the main ones: how many tiles are needed for work, that is, how to calculate the number of tiles for the floor. Here you need calculations to accurately determine the required amount of tiles for a bathroom or other room.
To do this, measure the length of the room and divide by the length of one ceramic tile. Also measure the width of the room and divide by the width of the tiles. Then multiply the two results obtained, after which you will get the required number of tiles for a given room.
For example, room length 3 meters and width 2 meters. Ceramic tile size 200x150 mm. It is advisable to convert to one unit of measurement:
- Room length 3 meters = 300 cm, and the width 2 meters = 200 cm.
- Tile 200 mm = 20 cm, and the width 150 mm = 15 cm.
- Now all that remains is to calculate:
- Divide the length of the room by the length of the tiles = 300/20=15 ;
- Divide the width of the room by the width of the tiles = 200/15= 13,3 ;
- Let's multiply the two obtained indicators = 15*13,3= 200 .
Happened 200 tiles for this room.
Option 2 for calculating the number of tiles
There is another calculation option that may be easier for you than the previous one. First you need to calculate the area of the room and the area of one tile. And then divide the floor area by the area of the tiles.
Let's look at it with an example. Let's take the indicators from option 1. Room length 3 meters and width 2 meters. Ceramic tile size 200x150 mm.
Here we convert the tile size to meters:
200 mm = 0.2 meters
150 mm = 0.15 meters
Floor area in the room: 3 m * 2 m = 6 m 2
Area of one tile: 0.2 m * 0.15 m = 0.03 m2
The floor area is then divided by the area of one tile: 6 m 2 / 0.03 m 2 = 200 pcs. That is, we will need 200 tiles.
Of course, it is advisable to take extra tiles if you spoil one or more when cutting or for the future. It's up to you to decide.
By the way, if mathematics and geometry are bad, then here ceramic tile calculation assistant, and this service is suitable for all types of tiles.
Correct calculation of the need for floor tiles
Repair work begins with the right choice technology and acquisition of relevant materials. Floor finishing work with ceramic tiles is no exception.
In our time, high-quality tiles have ceased to be a scarce finishing material, and floor coverings are not done so often that ceramics can be purchased for future use in large quantities. Therefore, it is necessary to calculate the consumption of facing material correctly, taking into account the specifics of the technology and the possibility of making spot repairs of the floor covering.
Correct is the calculation of flow rate with a minimum error, and only in a larger direction. This will save money and eliminate unpleasant surprises when there is not enough material and you need to at least buy more.
Despite its apparent simplicity, the calculation of the need for ceramics must be made taking into account many factors that influence the consumption of tiles:
- size and configuration of the room;
- type of flooring (straight, offset, diagonal);

Monotonous floor finishing with ceramic tiles using direct laying, diagonal laying or offset tiling is a common technology. Calculating the need for tiles in this situation begins with measuring the floor with a tape measure and calculating its area by multiplying the length in meters by the width.
6.3 m x 3.1 m = 19.53 sq. m.
To calculate in square meters the number of tiles required to finish this area, you need to add 10% to the resulting value and round the result up, taking into account the trimming of products during the gluing process and possible damage to the material.
Floor tile packaging
19, 53 sq. m. x 1, 1 = 21, 483 sq. m. We round up and get 22 sq. m. tiles
The packaging with ceramics indicates how many square meters of material are contained in a box of tiles, for example, 1.1 square meters. Dividing our obtained consumption value by this value, we get how many packs are required:
22: 1, 1 = 20 packs - the final result of calculating the need for tiles. If the value is fractional, then the number of packages must be rounded up to whole units.
Counting when laying diagonally
Sticking tiles diagonally allows you to hide defects in the geometry of the room, which justifies a slightly higher consumption of ceramics when using this type of flooring.
When laying tiles diagonally, 15% must be added to the floor area, since adjusting the ceramics when fastening in this way creates more substandard waste, and the result is also rounded up.
19, 53 sq. m. x 1.15 = 22.46 sq. m.
After rounding we get 23 sq. m. facing material, divide by the square footage of the ceramics in the box and get the amount of tiles expressed in packs:
23 sq. m. : 1.1 sq. m. = 20.9 packs. We round up and get how many tiles you need to purchase - 21 boxes.
If the room has a different shape (trapezoid, polygon, oval, circle), then the area of these figures is determined using the appropriate mathematical formulas, or the floor is divided into simple geometric components (rectangles, triangles), the area of which must be calculated separately and summed, and then, taking into account the type of flooring, apply an increasing factor of 1.1 or 1.15.
When laying tiles diagonally, the calculation is made in the same order as with conventional
Piece method for determining flow
This calculation of the need for material gives a smaller error and is used mainly when using expensive finishing materials using the direct laying method or when creating an artistic panel on the floor. When laying ceramics diagonally, this calculation method is not applicable.
Let's look at the calculation using a specific example.
Room dimensions: 6.3 m x 3.1 m.
Product dimensions: 0.25 m x 0.20 m.
With the direct method of laying ceramics across the room, the following number of sheets of ceramics will fit into its length:
6.3 m: 0.2 m = 31.5 pieces. Round up and get 32 pieces.
The width of the room will fit:
3.1 m: 0.25 m = 12.4 pieces. After rounding we get 13 pieces.
We multiply these values and get:
416: 10 = 41.6 packs. Round up and we get 42 packs of tiles.
Experts say that piece-by-piece calculation of tiles is more accurate.
Combined demand calculation
In this case, a sketch map of the floor finish is drawn up, measurements are taken of individual sections of the base and the format of the corresponding tile.
First, using the piecemeal method, the amount of ceramics involved in the composition of the panel or ornament in the center of the room is calculated, and then, in square meters or also piecemeal, you need to calculate how many sheets will be needed to decorate the background areas with monotonous cladding, taking into account the difference in waste between direct laying and laying according to diagonals.
Results
Using these recommendations, you can minimize the likelihood of errors in calculating the need for ceramics and save not only on the minimum amount of remaining material, but also on the absence of the need for additional trips to purchase tiles in case of shortage.
The technology of covering a floor or wall with ceramic tiles can probably be mastered by any skilled owner of an apartment or house, if, of course, he adheres to all existing rules and recommendations from experienced finishers. At first, of course, there may be mistakes, but with patience and diligence, things will definitely work out.
Calculator for calculating the required amount of ceramic tiles
When choosing a facing material, it is advisable to correctly determine in advance exactly how much of it will be needed. In this matter, the calculator for calculating the required amount of ceramic tiles, located below, will be an assistant to the reader.
A brief description of the calculation process will be given below.
Calculator for calculating the required amount of ceramic tiles
How is the calculation carried out?
The calculation, I must say, is the simplest. It is based on comparing the area of the floor (or walls) being finished with the dimensions of the ceramic tiles selected by the owner.
Surface area is easy to calculate.
What if the room has a complex shape?
There are usually no problems with calculating the area of a rectangular room. Questions can sometimes arise with complex configurations. Many examples, equipped with descriptions and convenient calculators, are contained in the article “How to calculate the area of a room” .
- The dimensions of the tiles are always indicated on the packaging.
- The interval between the tiles is also planned in advance - the seam for filling with grout.
- The usual reserve for cutting tiles is about 10%. If diagonal laying of tiles is planned, then more material may go into the scraps, so it is advisable to increase the reserve to 15%.
- It is worth purchasing tiles for the entire surface to be finished at once. A discrepancy between the article number or even the production batch of goods will immediately manifest itself as differences in color design lined surface.
At the same time as the tiles you must purchase tile adhesive And grout mixture for seams– the corresponding calculators can be found using the links provided.
What else is important to know about ceramic tiles?
In this matter, everything is important - from the nuances of choosing a material to the subtleties of the technology of laying cladding. A bunch of useful information concentrated in an article about s DIY installation of ceramic tiles .
How to calculate tiles for the floor
Any work related to renovation of an apartment begins with the choice of room design and selection necessary materials to bring an idea to life. Next, you need to calculate the required amount of paint, wallpaper and everything else that may be useful. Sometimes novice craftsmen have a very important question - how to calculate the tiles for the floor? Let's figure out how this is done.
Laying ceramic tiles
Correct calculation of tiles
Available now in construction stores different kinds tiles They differ not only in texture and color, but also in size - there are tiles both large and small. Among all the variety, there is sure to be an option that will suit the apartment owner both in appearance and in quality. But it’s not enough just to choose a tile in accordance with its decorative characteristics; you also need to correctly calculate the quantity required for finishing a particular room.
Types of tiles, prices
Previously, tiles were often bought for future use, since the material was quite scarce. Now you can safely buy only the quantity that is needed at the moment. This allows you to save money and spend it on some other types of materials that may be useful during repairs. Moreover, you can even count the number of tiles with an accuracy of one piece.
Advice! When purchasing such a fragile material as ceramic tiles, you should always have a small supply. It will be needed in case part of the tile is damaged during transportation or directly during repair work. Damaged elements cannot be used to decorate the premises.
Tiles need to be purchased with a small margin
Cover the walls with wallpaper, decorate the floors with laminate or self-leveling floors much easier than laying ceramic tiles. Therefore, the main advice for a beginner is that you need to purchase tiles with a small margin. Firstly, the reason for this is that the material is fragile and can easily be broken with one careless movement. Secondly, tiles, even in the same batch, may differ in color or texture, or have a somewhat non-standard shape.
The correct calculation of the number of tiles is the definition required quantity elements for finishing a specific place in the house, subject to a minimum error or rounding the required number up. It is in this case that it will be possible to avoid the fact that there is not enough material and you will have to go to the store again in search of the missing elements. The number of tiles is never determined by eye.
Calculating ceramic tiles for the floor
Despite the fact that doing the calculations seems to be a fairly simple procedure, there are some subtleties here. For example, it is important to take into account the size of the room where the renovation is being carried out, the chosen type of tile installation, as well as the shape and dimensions. It is also worth remembering that some elements will have to be trimmed, that is, they will not be used whole.
Advice! The floor area located under the bathtub can not be counted when determining the number of tiles. It won’t be visible there anyway, but you will be able to save a lot of money on purchasing ceramics, since this material is not cheap.
Laying ceramic tiles on the floor
How to calculate floor tiles - basic methods
You can determine the required number of tiles using one of several methods. They are applicable in all cases, even if the room where the floor is decorated has non-standard geometry. Of these, the one that seems most convenient to the master is selected. Let's get acquainted with methods for calculating the number of ceramic elements.
Important! To carry out calculations, you need to already know what size tiles will be laid in the room. And here it is important to take into account the chosen masonry pattern, as well as whether there is any pattern on the ceramic elements themselves.
Options for sticking ceramic tiles
By room area
The most understandable and familiar method is to determine the consumption of tiles in square meters, that is, by the area of the room. This method is ideal for laying ceramics of the same color, the same size, as well as in the case of simple or diagonal laying or with an offset.
Calculation of floor area
First, the area of the room is determined. The easiest way to identify it is if the room has a geometric correct form- square or rectangle. In this case, the length of the room is simply multiplied by the width value. Measurements are taken of sufficient length with a tape measure along the walls of the room.
Next, the resulting value - the area of the room - should be increased by approximately 10%. This will allow you to make the necessary supply of material (10% can be added after all calculations have been made). The final value is divided by the area of one tile (this is also the length and width of the ceramic product, multiplied by each other) - the result is the number of elements that will be required for the work.
If you need to cover a sufficiently large base with tiles, you can count the tiles in packs. To do this, you need to know how many square meters the coating packed in one box will cover. Then the area of the room with a margin can be divided by the area of the covering laid in one pack - the result will be the number of boxes of tiles.
On a note! If the final value in one case or another turns out to be fractional, then it is always rounded only up.
A more accurate calculation of the area can be made if you count the tiles individually. If the room has complex geometry, then you will have to tinker with the calculations. For example, you can conditionally divide it into regular geometric shapes and find out the area of each of them, then add the values and get a figure equal to the area of the entire floor in the room. You can also use various geometric formulas, which were studied in school.
How to correctly calculate floor tiles: three reliable ways
If you decide to lay tiles on the floor, then the first step is to walk around all construction stores. Then he takes a closer look suitable option. And then many realize that the worst difficulties are yet to come. Rises main question– how to calculate ceramic tiles for the floor and how much to buy so that there is nothing left over.
Why is this necessary?
The thing is that the process of laying floor tiles is more complex than wallpapering walls. Most people, who very rarely face serious repairs, are sure that it is enough to purchase such a quantity that there is only enough material to spare, and if there is not enough, then purchase the missing amount. But professionals do not recommend this approach.
The production technology of such a material as ceramics is quite complex. In different batches of products, the same pattern from the same manufacturer or brand may have different shades. It is far from certain that you will be able to purchase tiles with the required shade.
You can easily get out of this situation if you purchase ceramics with a reserve, but the cost of high-quality tiles is quite high, and if there is a lot of material left after the work, it is unlikely to be returned. Keeping it at home is also a bad option. There is only one correct way out - to spend an hour and calculate the number of ceramic tiles on the floor.
Let's start the calculation
There are simply no unique methods and formulas. The thing is that the final amount of materials depends on a huge number of factors. Many will say that it is enough to know the area of the room - but not everything is so simple. It is very important what configuration the subfloor has, what kind of finishing floor is planned, what size one tile is, whether the base is ideal for the installation process, and of course, the pattern is very important.
Method No. 1
First of all, let's see how you can count the tiles in the bathroom on the floor. The house is a typical high-rise building. Often, in standard premises The size of the bathroom is approximately 1.75 m x 1.7 m. Let's imagine that this room has a classic rectangular shape without any protrusions or niches. Let the tiles also be standard size– 333 x 333 mm.
Next, read the area, 1.75 m multiplied by 1.7. The result is 2.975 m. This value can be safely rounded to 3 m2. So, according to preliminary calculations, it turns out that only 27 whole tiles will be needed for finishing. However, there are nuances here - you need to count individually.
To do this, the width of the rectangle is divided by one of the sides of the ceramic tile - 1.7 m/0.333 mm = 5.1 pcs. This value can also be rounded - the result is 5.5 pcs. Then, the same calculations are performed for the other side. After rounding, the same figure is obtained - 5.5 pcs.
Next, you should multiply the results obtained. So, 5.5 x 5.5 = 30.25 pcs. You can round the value up again. So, the end result is 31 tiles. As can be seen from these calculations, the results differ greatly by as much as 4 pieces. It is not at all necessary that the length of the row during the laying process be a multiple of the length of one tile. Using this method, you can calculate the exact number of tiles for any floor.
In addition, one should take into account production defects, as well as various waste, because when laying the tiles you will have to cut them. It is worth adding to this also various niches in the room, as well as ledges. They can be quite complex configurations. As a result, it is worth taking 34 pieces. The most economical installation method is the seam-to-seam method without any shifts. However, here too you need permission for various expenses.
When laying, do not try to make seams along the lines of the walls. If the wall is not too smooth, then visually, from the cut, this unevenness will be very visible.
If you decide to do all the work yourself, rather than take the help of qualified specialists, but have no experience in this matter, you should not take on complex ornaments and designs. It’s best to start with classic solutions – butt-to-edge.
Method No. 2
The first method is simple. And the second one is even simpler and is suitable even for lazy craftsmen. In many construction supermarkets, as well as in decent online stores, you can calculate floor tiles using a special calculator. This simple program, which can make life much easier.
However, the calculator will only help you perform necessary calculations. You will still have to take accurate measurements of the premises, otherwise inaccurate dimensions may lead to incorrect results. And such calculators are needed for accurate calculations. The best option, of course - count everything manually. Then, having received the final figure, you can check the program. If there are minor discrepancies, then everything is correct.
Method No. 3
This method can be used when laying tiles with a rather complex pattern. It can be a herringbone pattern or the pattern runs diagonally across the tile. Also, this method is suitable if the floor does not have the shape of any regular geometric figure.
Naturally, you can divide the floor surface into more simple figures, and then perform the calculation using the first method for each piece separately, and then simply add up the results obtained and, with a minimum 15% margin, calculate the required amount of material. However, this is not an accurate and time-consuming option.
Tile laying specialists, based on experience, recommend using a checkered sheet or graph paper. An exact copy of the floor is drawn on it on a convenient scale. Then, according to the intended drawing (while respecting the scale), you should draw out exactly where each tile will be laid.
After this, all solid tiles are counted, and marks are set on the plan. Tiles that will then be cut to less than half are marked separately, since 1 tile (if cut) can be laid in two places.
This way you can find out exactly how many ceramic tiles you will need to finish the floor in any room. It is very convenient to know this figure in advance - then you can purchase the strictly required amount of material and a little more in case of defects.
We count the glue consumption
When laying ceramic tiles, many factors influence adhesive consumption. This includes the type of tile, its thickness, the quality of the base and the laying technology. Also, the type and brand significantly influence the consumption. adhesive composition, weather, master's qualifications.
Tiles can be porous and hygroscopic. The base may not be level enough. Porous tiles can absorb more adhesive solution than glazed. Many manufacturers offer to purchase universal glue that is suitable for different types ceramics. You should pay attention not to products with an uneven surface - such tiles require a lot of glue.
Ceramic tiles of larger sizes and weight will increase consumption. So, for a product 10x10 cm with a layer of adhesive solution it should be 2 mm. If the tile has a size of 20x30, it will be from 2 to 3 mm. For all products that have larger size, the adhesive layer is from 4 to 5 mm.
The base on which the tiles will be laid must be as level as possible. If the height differences are up to 3 mm, then thin-layer laying technology can be used. This is where the glue is applied thin layer just so that the tile adheres to the base. If the height differences are large, then the layer thickness will be greater. However, modern manufacturers produce special leveling compounds. They are applied in a layer of up to 3 cm. This is a thick-layer technology.
The first method involves a special calculator, which is necessarily available on the manufacturer’s website. With its help, you can easily determine the amount of adhesive solution per 1 m2 and for the entire area of the room. You just need to provide the program with information about the brand of adhesive, surface area and type of tile. The result is given in kilograms.
According to the second option, you will have to count manually. If you need to know the amount of glue per 1 m2, you need to take half the thickness of the tile and average consumption adhesive composition. These numbers need to be multiplied and the result will be ready. However, it should be borne in mind that the obtained figures are not very accurate.
The third method calculates the glue consumption per cement based. It is better to purchase these compounds in bags weighing 1.3 kg. So, its mass of 1.3 kg should be multiplied by the thickness of the glue. The number will ultimately be the required expense.
The average consumption is written on the bag. However, this figure was obtained on an ideal base and an adhesive layer thickness of 3 mm. For example, for 21 sq. m. about 76 kg of mixture can be consumed. However, ideal subfloors in apartments are still worth looking for. Therefore, glue must be purchased in large quantities. But this is not entirely important, because the material can be purchased at any convenient time.
We calculate the grout consumption
Grouting the joints is the last stage of installation. To correctly calculate the amount of grouting materials, you can use a simple formula.
So, take half the perimeter of one tile and divide this figure by the area of the same tile. The resulting figure is then multiplied by the thickness. The result is multiplied by the width of the seam, and then multiplied again by the shrinkage factor. This coefficient is 1.5. As a result, the required mass of materials per 1 m2 in kg is obtained. So, if the seam is 2x3 mm, the tile area is 0.04 m2, then judging by the calculations, 1 kg of grout mixture should be enough for 3.5 square meters. m.
A preliminary calculation will allow you to plan your renovation budget and think through the bathroom design in detail. If you correctly calculate the number of tiles, you will not have to purchase additional material during the finishing process.
To measure the room you need to use a tape measure. Most exact values can be obtained using a laser device. Having found out the parameters of the bathroom (height and length of the walls, dimensions of the doorway), you can make preliminary calculations number of tiles. The simplest option is when the room has the outline of a rectangle or square. In this case, it is necessary to measure the minimum number of walls.
If the bathroom is complex shape, it is necessary to carefully measure all protruding elements and take into account existing niches.
The results need to be recorded on the diagram, so it will be easier to calculate the materials. A drawing made to scale will also allow you to take into account all the details of the bathroom design and correctly plan the arrangement of furniture. The calculation algorithm is influenced by the type of laying of floor tiles (diagonal, rectangular, rhombus, etc.).
2. Basic rules for calculating tiles
The calculation algorithm is quite simple. When counting exact quantity tiles will need formulas for determining the perimeter and area of a rectangle.
To calculate the wall area we use the following formula:
Parameters A and B (width and length of the room) alternate depending on the specific area.
The perimeter of the rectangle is calculated by the formula:
P = (B + A) * 2.
Designations in formulas:
- S - area of a certain surface in the bathroom, sq.m;
- P - designation of the perimeter of the room, m;
- A - bathtub width parameter, m;
- B - length dimension of the room;
- H is the value of the wall height.
Calculation scheme:
- The total area of the room is obtained by adding the square meters of individual bathroom walls;
- Then, from the obtained value, you should subtract those areas that will not be laid with tiles, for example, the area of the door opening to the room or window.
In order to reduce material consumption, cladding is not done in the space under the bathtub. This option is possible if you plan to install a decorative screen. In this case, the height of the room for calculation is measured from the top level of the side.
Some sites provide a special calculator that allows you to determine the required volume of material for purchase. Using such programs, you can make the task easier when calculating the amount of material if tiles of different shades are combined.
3. Calculation of tiles for a bathroom with a total area of 4 sq.m.
Main dimensions of this room:
- Wall with opening - 2150 mm;
- The length of the short wall is 1900 mm;
- Doorway - 700x2000 mm;
- Room height - 2700 mm.
Dimensions of the selected bathroom tile collection:
- Wall tiles white- 500x250 mm;
- Green wall tiles - 500x250 mm;
- Decor - 500x250 mm;
- Green floor tiles - 500x500 mm.
Facing plan
Tiles intended for flooring are laid in one tone. On the wall with the door it is planned white tiles. The remaining surfaces of the walls are supposed to be done with alternating colors according to vertical stripes and also add decor.
Calculation of floor tiles
We determine the parameter for the area of one tile: S = 0.5 x 0. 5 = 0.25 sq.m;
- Total floor area: S = 4 sq.m;
- Calculation of the number of tile elements for the entire floor area: 4 / 0.25 = 16 pieces.
Calculation of tiles for bathroom walls
Wall decoration elements have the same format (width and height).
- One of the walls (with an opening) is covered with white tiles, let's calculate its area without the door: S = (2.15x2.7) - (0.7x2) = 5.805 - 1.4 = 4.405 sq.m;
- Area of one wall tile: S = 0.5 x 0.25 = 0.125 sq.m;
- Number of white tiles for a wall with an opening: 4.405 / 0.125 = 36 pieces (round the number up);
Let's consider another calculation method, which is suitable for surfaces with tiles of different colors.
- Number of tiles in width for other walls:
1.9 m: 1.9 / 0.5 = 3.8 pieces;
2.15 m: 2.15 / 0.5 = 4.3 pieces; - Number of tiles around the perimeter of three walls: (3.8 x 2) +4.3 = 11.9 pieces;
- We calculate how many elements fit in height: 2.7 / 0.25 = 10.8 pieces.
This value can be rounded down if you plan to install a stretch ceiling; - In this example, stripes of tiles of different colors are oriented vertically.
Laying green tiles is planned in 8 vertical rows, taking into account decorative elements: (8 x 10.8) - 4 = 86.4 - 4 = 83 pieces; - Number of white tiles for three walls in width: 11.9 - 8 = 4 pieces.
For three walls in total: 4 x 10.8 = 44 pieces.
Final volume values of tiles for bathroom walls
White tiles: (36+44) = 80 pieces;
. Green tiles: 83 pieces;
. Decor: 4 pieces.
When calculating the number of tiles, it is better to take into account the safety factor. If the material is damaged, the remains can be used without discrepancies in shades.
