Main question when renovating the floor - how to calculate the tiles for the floor so that there is enough of it with a minimum margin. After all, sometimes tiles cost quite a lot of money, and if you buy a lot of excess material, it is very difficult to return it. And the technology for producing floor tiles is quite complex, and even in one batch there may be individual strips with different parameters And color shades, so it can be very difficult to purchase the right color.
Calculation
Let's start the calculation
It should be noted right away that there are no unique formulas; any calculation will be approximate, since many different factors must be taken into account.
Important points are the configuration of the rough base, what size a single tile is, how ideally the base is leveled, as well as what method of laying the floor tiles was chosen.
Calculating floor tiles by area is the easiest way to calculate tiles, but it is also the least accurate. And it is also used only when the tiles are laid seam to seam.
The algorithm for calculating the number of tiles is as follows:
- The room is measured along its perimeter;
- Next, the obtained values are multiplied and thus the floor area is obtained;
- To calculate the area of one floor tiles its length and width are measured, and the resulting values are multiplied;
- Next, we divide the area of the room by the area of the tile, and both initial values must be reduced to a single unit of measurement;
- Next, to the resulting number, as a mandatory requirement, you must add at least 10 percent for pruning and possible defects. And when using diagonal laying you need to add the full 20%.
If there are areas on the floor that are not covered, then calculate the amount of material required without taking this area into account.
Calculation by number of rows
Calculating floor tiles based on the number of rows is more accurate. This method The calculation is based on an accurate calculation of the number of required rows. In this case, the resulting number must be rounded up, since the presence of fractions informs us about the need to trim the tiles.
- The first step is to determine the length and width of the room;
- Next we produce the following actions: divide the length of the room by the length of one tile. Thus, it turns out to calculate the number of rows;
- The next step is to calculate the number of tiles in an adjacent row. To do this, divide the width of the room by the width of one tile;
- Next, all obtained values must be rounded to whole numbers;
- We add at least five percent for pruning.
The above method allows you to calculate the number of tiles much more accurately, since it takes into account the number of non-integer tiles. Compared to the first method presented, the difference can be up to 15 full-size ceramic slabs, and in financially this can be quite a significant amount.
Schematic counting method
Both of the above methods are most focused on quite familiar and standardized tile placement patterns, but the calculation of slabs laid diagonally is carried out according to a different principle. For correct calculation, it is necessary to develop a laying diagram on paper, and this means literally counting the number of slabs.
To implement this, you will need paper with a millimeter notch. The exact values of the room parameters are plotted on it on the appropriate scale and the required cladding zones are indicated. Then the area occupied by one tile is precisely determined and drawn on paper, according to the chosen scheme and the chosen direction of installation. In addition to whole areas, be sure to also draw half areas, and then simply count the resulting slabs.
This way you will not only get ready plan placement of tiles on your floor, but also exact amount required coating elements.
Payment on the Internet
At the moment, the Internet can offer many different online calculators for counting required material, using them as the only source of calculating the required material is unreasonable, but as a check of the result you received, it is a very good option.
Remember, a correctly performed calculation is a guarantee quality repairs at minimal cost.
It is important to avoid mistakes when tiling a bathroom with expensive imported tiles, as well as additional elements and accessories - cornices, decorative borders, inserts. In this article we will explain how to calculate how many bathroom tiles you need.
In fact, it is not difficult, you just need to take the correct measurements of the room and apply some mathematical calculations. Eat various options, but here we will look at the simplest method using the example of given specific parameters.
Laying different tiles
List of components for the tile collection
To make the calculation, you need to make a list of the collection’s components:
- floor (31x31cm);
- dark wall (25x30cm);
- light wall (25x30cm);
- horizontal border (6x25cm);
- decor (25x30cm);
- pencil (2x25cm).
For example, let's take a bathroom measuring 1.8m x 1.9m and a height of 2.7 meters.
The doorway is 0.7m x 1.95m. We carry out the calculations for smooth walls, without taking into account possible niches and protrusions. For clarity and for ease of calculation, it would be useful to draw a plan of the room, marking the dimensions of the walls, doorway, and other planes of interest that need to be calculated.
Calculation of floor tiles
Original version bathroom floor installation
But the calculation by units is considered more accurate. Divide the width of the floor by the size of the tiles:
1.8m: 0.31m = 5.8, round up, to the whole or to the half. We get 6 horizontally.
Divide the length of the bathroom floor by the size of the piece:
1.9m: 0.31m = 6.12. Vertically we have 6.5.
The total quantity for the floor is: 6 x 6.5 pcs = 39 pcs.
As a result, we see that the calculation for tiles differs from the calculation for area. The difference of three units compared to the first calculation is due to the fact that the dimensions of the surface of the floor or walls are not a multiple of the dimensions of the slabs, so they have to be cut. It is also necessary to cut in places of protrusions, niches, pipes, etc. We write down the first result - 39 floor slabs.
Calculation of tiles for walls
All components have the same width - 25 cm. Divide the width of the wall by the width of the slab:
1.8m: 0.25m=7.2 ≈7.5 pcs. ,
and the length of the wall by the width of the tile:
1.9m: 0.25m=7.6≈8 pcs.
In total around the perimeter we get: 7.5 pieces x 2 + 8 pieces x 2 = 31 pieces.
Now you need to subtract the lining for the doorway from the total quantity:
0.7m: 0.25m=2.8≈2.5 (we round down to have a better margin than a deficit.
Subtract from the total: 31 - 2.5 = 28.5.
The row of borders around the entire perimeter is 29 pieces. Since the pencil is placed on both sides of the border (top and bottom), the required quantity of this element is 58.
Laying with decorative borders and pencils
We lay the dark tiles in three rows - the height will be 90 cm. The height of the bathroom is 60 centimeters, there will be 1 dark row above it. Multiply 3 rows by 28.5 (the number of tiles in a row along the perimeter). We get 86 pieces.
The light one will be glued above the border with a pencil and up to the ceiling. From the total height of the room (2.7m), subtract the height of the dark room (90 cm) and the border with a pencil (6cm+2cm+2cm=10cm):
2.7 m - 0.9 m -0.1 m = 1.7 m (height of cladding with light material).
Divide 1.7 m by the height of one:
1.7m: 0.3m= 5.67≈5.5.
In this case, we round down, since when installing a beautiful suspended ceiling you can save some money.
Decors in the bathroom can be glued at your discretion
Now multiply 5.5 in height by 28.5 around the perimeter:
5.5 x 28.5=156.75≈157 pieces.
We return to the area of the wall above the door, which also needs to be lined. Here the number of units in width is:
0.7m: 0.25m=2.8≈3pcs (rounded to the nearest whole number).
The height is 2.7m-1.95m = 0.75m.
0.75m:0.3m= 2.5 pcs.
We multiply 3 in width by 2.5 in height, we get 7.5 (rounded) = 8.
The total number of light ones is: 157 +8 = 165 pieces.
We glue the decors at our discretion and taste: 1 or 2 on each wall, in a checkerboard or other order. Let the tiles that will be replaced with decors (if there are not very many of them, of course) be left in stock just in case (to replace those damaged during use).
Now you have a general understanding of the calculations. If done carefully, they will prevent situations where there may not be enough tiles when laying tiles, and will also save you from unnecessary cash costs.
When starting to renovate rooms in which you plan to tile, after choosing the collection you like, you will immediately be faced with the question of how to correctly calculate the quantity required tiles. If you purchase it with a large supply, then later you will not be able to return the excess to the seller, and therefore will incur unnecessary expenses. If you take it exactly by area, you may encounter a situation in which some tiles will be rejected or broken during the gluing process, and if a given tile is not available, then you will have to wait until these few tiles are delivered to you.
There are several methods for calculating the number of tiles for renovation in a particular room.
Method number 1. How to calculate tiles for the floor.
Floor tiles are usually considered quite simple. To do this, you need to find the area of the room by multiplying its length by its width. If the room’s floor shape differs from a simple rectangle and has a complex configuration, then you need to divide it into several simple figures, find the area of each of them and sum the resulting areas. For example, you determined that the area of the room is 12 m2. Then you need to find the area of one tile from the selected collection. Let it be 0.5x0.5 meters as an example. This means that the area of one tile is 0.25 meters. We divide the area of the room by the area of the tiles and find that we need 48 tiles for the floor. This is in the ideal case when the joints of the tiles with the dimensions of the floor are such that the tiles will lie on it without undercuts. But, as you know, nothing is perfect, undercuts cannot be avoided, so you need to take the tiles with a margin of 10 percent, which for our example will be 48 + 48 * 0.1 = 52.8 tiles. We round up and find that we need 53 tiles for the floor. Method number 2. How to calculate bathroom tiles.
If in the previous example everything is calculated quite simply for the floor, then how to correctly calculate wall tiles for the bathroom, where the task can be complicated by numerous inserts of decors and borders? IN in this case you need to add up the length of the walls to get the perimeter of your room. Next, you need to draw on paper one column of tiles from the floor to the ceiling, so that before your eyes there is an alternation of dark tones with light ones, and the rows of the border are also visible. After this, we take the perimeter of the room and divide it by the width of one tile of your choice, which gives us the number of tiles in one row. Fractional numbers are rounded up. Rows of tiles of the same tone are summed up and the desired value is obtained. If there are doorways, their area is determined, divided by the area of one tile, and then subtracted from the previously calculated amount. The final stage will be to increase the calculated value of the number of tiles by 5-7% per cut.
As an example of such a calculation, consider the following figure.
It shows one column of tiles measuring 23x35 cm from floor to ceiling in the selected layout. How to calculate the number of tiles for it? For example, let's take a room with a perimeter of 10 meters. This means the number of tile columns will be equal to the perimeter divided by the width of one tile 10/0.35=28.6. Round up and get 29. The dark tile will be laid in five rows, which means you need 5*29=145 pieces. The border comes in two rows, so it will require 2*29=58 pieces. The light tiles are laid in four rows and will require 4*29=116 pieces. And finally, the decor is laid in three rows and you will need 3*29=87 pieces. We increase the resulting quantity by 5-7% and get the final value of how many pieces of tiles we need. If necessary, we transfer items to square meters by multiplying the number of tiles by its area.
Method No. 3. How to correctly calculate the number of tiles.
In large stores selling ceramic tiles they may give you required quantity tiles for the size of your room in a special computer program. The calculation turns out to be quite accurate. This method can be used as a comparison with the results you obtained during manual calculations.
Method number 4. How to calculate tiles with complex masonry.
The previous two methods work very well for basic tile laying, which is the most commonly used. But how to calculate ceramic tiles, if it is planned to be laid diagonally, or in a running start? In this case, drawing out the layout on paper will help you.
You need to take a squared notebook sheet, or a sheet of graph paper, determine the appropriate scale of the room, and draw its perimeter. For walls, you need to draw each of the four walls to the selected scale. Then, focusing on the cells on the same scale, draw the planned pattern for laying the tiles.
Then everything is quite simple. You count whole tiles that will be laid without trimming. For convenience, so as not to get lost when counting, mark them with any symbol or icon that they have already been counted. It will look something like this.
Then count the tiles with cuts. If two cut pieces can be obtained from one whole tile, then one tile is considered to be required. You also mark the counted cut tiles with some symbol. When the final quantity is obtained, as in all previous examples, it must be increased by a safety factor equal to 1.10...1.15, which takes into account errors in calculations, or unsuccessful tile cuts, which are inevitable in large quantities during complex installation.
Thus, it is possible to calculate with sufficient accuracy the amount of tiles required for any method of laying them and for any room. Carefully performed calculations will save you from unnecessary financial costs and situations in which you may not have enough tiles when laying them.
Why and how to calculate tiles for the bathroom? This is necessary to purchase the required volume of building materials: you will not overpay for unused material, and the money saved can be spent, for example, on purchasing tile adhesive.
Calculation of tiles for bathroom walls
- Calculate the area. Measure the perimeter of the room and multiply it by the height of the walls. For example, the height of a room is 2.7 m, width 2.5 m, length 3 m. Find the perimeter: 2.5 + 2.5 + 3 + 3 = 11 m. Multiply the perimeter by the height: 11 × 2.7 = 29, 7 m2. The area of the door and windows, if any, is subtracted from this number. Let's say that after subtraction we get an area of 28 m2.
- Finding the area of 1 tile. For example, the dimensions of one tile are 0.3 × 0.2 m. Then its area is 0.06 m2.
- Find out the number of bathroom tiles. The area of the walls is divided by the area of one tile: 28/0.06 = 467 pieces. 10% stock is another 47 pcs. The total quantity is 514 tiles.
How to calculate the number of tiles for the floor
The mathematical calculation of the number of tiles per floor is similar to the algorithm described above:
- Find the floor area.
- Divide the floor area by the area of one tile.
Common Questions
- How to calculate the number of tiles for a bathroom if they are laid diagonally on the floor or wall? In this case, the counting algorithm is no different.
- How much reserve should I make when calculating bathroom tiles? Allowable stock tiles from its estimated quantity - 10%. Buying a larger volume of tiles is unwise for reasons of economy; buying less is risky, because you also need to take into account the grout joints for the tiles.
- How to calculate how many tiles are needed in the bathroom if the floor area is partially covered by a bathtub or shower? Just subtract it from the total floor area.
As seen, simple calculations allow you to find out how many tiles you need in your bathroom. The principle of calculation is also relevant for
Getting started finishing works in the bathroom, you first need to calculate and purchase the required amount of material. It is advisable to buy the entire volume at once, since the next batch may differ in tone, so calculations must be made very accurately. In this case, tiles are used to finish the walls and floor. Manufacturers offer material of various shapes and sizes. The number of tiles needed for the bathroom will largely depend on which collection is preferred. There are several calculation methods that we will introduce you to today.
Preparatory stage
Before you begin the calculation, you need to carefully measure the bathroom using a tape measure or rangefinder. The following parameters are required for the calculation:
- Wall height.
- Width of walls.
If the walls have correct form, it will be enough to make two or three measurements. If there are niches or various protruding elements, you will need to measure their parameters too and clarify the dimensions of the door.
Even if at first glance the walls seem perfectly smooth: square or rectangular, be sure to take several control measurements. This will avoid errors in calculations.
Required quantity of floor tiles
First way
Calculations begin with determining the floor area. To do this, its length is multiplied by its width. Then the area of one tile is calculated in the same way. After this, the first value is divided by the second, and the resulting result is rounded up. The result is an approximate value, which experts recommend increasing by 5%, multiplying by a correction factor of 1.05. The resulting value is again rounded to the nearest whole number.
As an example, consider a bathroom that has a ceiling of 2.65 m, walls of 1.8 m and 1.7 m and a door 0.6 m wide. In such a case, if floor tiles 33 cm by 33 cm, you will need: ((1.8*1.7)/(0.33*0.33))=28.1 pieces; 29*1.05"31 tiles.
Second way
We begin calculating the number of tiles for the bathroom by determining the number of tiles that will need to be laid in length and width. To do this, divide the length and width of the room by the length and width of the tiles, respectively. We multiply the resulting values by each other, round to the nearest whole number and also increase by 5%.
Based on the above example, we obtain the following sequence of calculations:
- 1.8/0.33=5.5 pcs.;
- 1.7/0.33=5.2 pcs.;
- 5.5*5.2=28.6 pcs.;
- round the value obtained in step 3 to 29;
- 29*1.05=30.45 pcs., i.e. To finish the floor (after rounding up) you need to purchase 31 tiles.
If one of the calculation methods results in a larger value, you should choose it. However, it is worth noting that sales consultants prefer to use the first option.
Required quantity of wall tiles
First way
To determine how many bathroom tiles are needed for wall cladding, we calculate the perimeter of the room. To do this, we sum up the lengths of all its walls. If we are talking about a standard bathroom, just add the length and width and multiply by 2. In our example: (1.8+1.7)*2=7 m.
Based on the perimeter, the required number of friezes is calculated. To do this, the width of the door is subtracted from the perimeter of the bathroom. The resulting value is divided by the length of the frieze or border, respectively.
If you wish, you can save money by not covering the part of the wall located under the bathtub. In this case, it will be necessary to subtract the area pertaining to this area from the general calculations.
So, for example, assuming that the dark tiles will be laid to a height of 1 m, we find that the height of the light top will be equal to: 2.7 m -1 m – 0.08 m (frieze height) = 1.62 m. Now you can calculate the required number of tiles. For this:
- We calculate the area that light and dark tiles will occupy.
- We divide the resulting values by the area of one tile.
- Round to the nearest integer value.
- We increase by 5%.
- Round to the nearest whole value.
In our example we will need:
- Dark tiles: (7-0.6)*1/(0.2*0.4)=52.5 pcsÞ53 pcs * 1.05=55.56Þ56 pcs;
- Light tiles: (7-0.6)*1.62/(0.2*0.4)=55.05 pcsÞ56 pcs * 1.05=90.3Þ91 pcs.
If planned decorative inserts, then the amount of light or dark tiles must be reduced by the amount of purchased decor
Second way
In this case, we lay out the layout of each wall to understand how many tiles can be placed in horizontal and vertical rows. In this case, the tiles that need to be cut are taken into account as whole. We increase the resulting value by 5% to insure ourselves in case of marriage or battle. We calculate the required number of dark, light tiles and borders and go shopping.
Thus, knowing the above methods, everyone can independently calculate how many tiles are needed for a bathroom. You just need to take the correct measurements, decide on the type of tile, as well as how it will be placed on the wall and floor.
