Before 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 this case, the edges of the 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. Consider the fact that if ceramic tiles are laid diagonally, the consumption 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 that you are going to tile with 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 did not perform a piece-by-piece calculation, but based on the surface area, you would make a rather significant mistake.
Return to contents
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. Tile flooring was and remains best choice when it comes to bathroom decoration. After all, such properties of ceramics as strength, moisture resistance, and aesthetics are ideally suited to the operating conditions of a given room. But due to the fact that the cost of tiles is not the lowest, there is always the intention of finding out how to calculate the tiles for the bathroom. Nobody needs extra expenses
for repairs, but there must be exactly enough material so that during the repair process you are not distracted by unnecessary troubles.
What is this article about?
To calculate the tiles for the bathroom, you need to take a ruler and measure the room. That is, measure the length of all sides of the walls. It is easier to measure an area represented by a rectangle or square. In the first situation, two sides are measured, in the other, one.
If there are various curved areas in the room, all parts are measured. The results are recorded and a scale plan is drawn up. He will help in compiling design project repair. On the plan you can indicate the installation locations of plumbing fixtures and furniture.
Basic calculation formulas
When calculating bathroom tiles, you should use the basic formulas for calculating the perimeter of a rectangle and its area.
The area is determined according to the formula:
and the perimeter is calculated as follows:
where the letters express the parameters:
- S – area expressed in square meters;
- P – room perimeter;
- D – wall length;
- L – width;
- H – wall height.
The area of all walls is calculated as the total sum of the found areas of all walls. Having found this value, the areas of those surfaces that are not subject to cladding (door and window openings, the space behind the bathroom) are minus from it.
Please note: sometimes, for reasons of economy, they do not plan to tile the wall, which will be hidden behind the bathroom. When choosing this finishing option, the wall area is calculated by measuring the height from the side of the bathroom.
These formulas are the basis for calculating the amount of tiles for the bathroom. In addition, to determine the quantity facing material information such as:
- laying diagram;
- planned color scheme of finishing;
- the need for adjustment to the pattern of elements;
- presence/absence of decorative elements (borders, inserts) in addition to the main coating.
Example of volume by area calculations
To illustrate how to calculate the number of tiles in a bathroom, let's look at examples. Presumably, the volume of material must be calculated for a room with the correct rectangular dimensions, in which the following measurements were made and recorded:
- shortened wall - 2.3 m;
- long wall - 3.2 m;
- wall height - 2.5 m.
The calculations will look like this:
The perimeter of the room with these measurements will be 11 meters = 2.3*2 + 3.2*2.
The area of the shortened wall is 5.75 m2 = 2.3 * 2.5.
Whereas long wall the area will be 8 m2 = 3.2*2.5.
The total area of the room will be 27.5 m2 = 5.75*2+8*2.
But the cladding area will be smaller. Since the area of the doorway will be removed from it. Which is 1.32 m2 = 0.6 * 2.2, where the width of the opening is 0.6 meters and its height is 2.2 m.
Then the area that needs to be tiled will be equal to 26.18 m2 = 27.5 - 1.32.
In this case, the floor area for cladding will be 7.36 m2.
Examples of calculations for floors
For example, choice flooring fell on the elements square shape with side lengths of 50 by 50 cm. Therefore, the area of each tile will be equal to 0.25 m2.
To determine how many tiles you need for a bathroom floor, you should divide the floor area by the area of one element. If we take the data from the example above, then 7.36/0.25 = 30 tiles (rounded up).
Previously, we looked at how to calculate bathroom tiles of the same type. However, not many people use the same type of tile. Often the option of combining elements is used. In this situation, it remains to be seen how many tiles would have to be purchased different types. Specialized specialists can help with this computer programs.
Count flooring perhaps in a different way. That is, count not according to the floor area, but individually. To do this, you also need to know the length and width of the bathroom. If we use the data from the previous example, the sides of the room will be 230 cm, 320 cm. If the tiles have a side of 50 cm, then the width will require 230/50 = 4.6 elements (rounded up to 5 whole pieces). This means that 5 tiles will fit in one row in width. Next, we calculate how many rows will be laid in length 320/50 = 6.4, round to 7. Then multiply 5 pieces in one row by 7, we get 35 pieces. Don't forget to add a couple or three pieces in reserve. Therefore, we will inform the seller that we have purchased 38 pieces.
Now let’s compare the results obtained from the example, where calculations were carried out by floor area and the data where the quantity was calculated individually. The difference is 8 pieces. That is, so many would not be enough to cover the floor and they would have to be purchased in the future. The second calculation option is more accurate and it makes more sense to use a piece-by-piece calculation.
Wall covering quantity
To calculate the amount of tiles for the bathroom on the walls, it is best to perform calculations separately for each partition. 250 cm (wall height) must be divided by 33 (tile side in cm) = 7.57 (or exactly 8) pieces - in a row according to the height. 230 cm (wall width) divided by 33 (tile side in cm) = 6.97 (or 7) pieces will lie in a row according to the width. We multiply 8 with 7, we get 56 units with sides of 33 and 33 cm. Needed for a smaller wall. By analogy, the number of tile samples needed to finish the larger side is calculated. Makes 80 tiles.
Accounting for door space
For example, the height of the door is 180 cm. Divide it by 33, we get 5.45. Round down, it comes out to 5 pieces in height. The door width is 75 cm, divide it by 33 cm (side of the element), we get 2.27. Rounding down, we get 2 elements in width. We multiply 5 by 2, we get 10 pieces. If we subtract them, for example, from 80, we get 70 elements.
Counting the tiles on the wall, where part of it is covered by the bathroom, is done in a similar way.
Example of calculations with decorative inserts
For calculations, consider materials with the following dimensions:
- rectangular wall elements - dimensions 20 cm x 30;
- pencils - 1.5 x 20 cm;
- borders - 10 cm x 20 cm.
Let's count total number borders with pencils. Why divide the perimeter by the length of each fragment. We remove the width of the doorway from the perimeter value. With our data it will be like this: (11 - 0.75)/0.2 = 51.25. Round up to a higher value, we get 52.
Since the pencils are placed on each side of the border tile, its consumption will double, in other words, 104 pieces will be needed. Next, the area that the tile will occupy is calculated.
Please note: if a direct layout of elements is chosen, then 5% of the material should be added to the calculated number of tiles, and when choosing more complex layout patterns (for example, with a diagonal arrangement of elements), the calculated number of elements is increased by adding 15% of the material.
These examples are enough to do the calculations yourself. Knowing them, calculate the required number of tiles, taking into account doorways and inserts of decorative elements.

Production repair work begin 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 it is necessary to purchase ceramics for future use. large quantities. Therefore, it is necessary to calculate the tiles for the floor 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 big side. 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 square meters. 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, its length will fit next quantity ceramic sheets:
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.
Bathroom renovation is rightfully considered one of the most expensive and complex. The complexity is due to the presence of various protrusions in the room: built-in cabinets, pipe boxes, door and window openings, etc. Of course, calculate the quantity required tiles going to the bathroom does not seem to be an easy task, but it is quite possible. The main thing is to approach this process with special care and scrupulousness. This will avoid unnecessary extravagance in repair costs.
The Internet is replete with various online programs according to tile calculations, but still the percentage of error in them is quite high. It is more advisable to calculate it yourself, excluding errors.
To begin with, you need to decide which one tiles will do to your bathroom. Modern market building materials offers ready-made kits.
- It should be taken into account that in small room Small tiles would look appropriate.
- With a low ceiling, tiles of an elongated vertical shape will visually increase the height.
- To prevent the possibility of slipping on wet floor in the bathroom, you need to choose tiles with relief.
- It is a good idea to check the perpendicularity of the walls before laying the material. Otherwise, the laid tiles will highlight all the imperfections and require a large consumption of glue, which will affect the amount of money spent.
Calculation of the required number of floor tiles in the bathroom
So, having decided on the choice of tiles, the first thing you need to do is measure the width and length of the room. To understand how to correctly calculate the number floor tiles, let's give a clear example.
Conditional data:
- Length and width of the room – 3×3.5 m
- Length and width of floor tiles – 40×40 cm
Calculation according to the formula:
N = S p / S pl. , Where
N – quantity of material, in pcs.,
S p – floor area, m 2
S pl. – area of one tile, m 2
S pl. = 0.4*0.4 = 0.16 m2
S p = 3*3.5 = 10.5 m2
N = 10.5/0.16 = 65.625 m 2, by rounding we get 66 pieces, and taking into account defects and damage 66+5% = 70 pieces.
How to correctly calculate the number of wall tiles
Additional conditional data:
Room height – 2.5 m
Lenght and width facing tiles– 25×33 cm
Length and width of the border element – 8×20 cm
Length and width of the doorway – 2.1×0.4 m
Estimated height of the dark bottom – 0.9 m
To calculate the amount of facing material we use the formulas:
- 1. N= SV.S./S pl, Where
S h.s – area of all walls, m 2
Spl – area of one tile, m2
- S v.s. =(H*R v.s.)-S d.p., Where
H – room height, m
P w.s. – perimeter of all walls, in m
S d.p.. - doorway area, m 2
- R v.s. = (a+ d)*2 , Where
a, d – length and width of walls, m
- Spl = a 1 * d 1 , Where
a 1 ,d 1 – length and width of the tile, in m 2
Calculation:
R v.s. = (3+3.5)*2 = 13 m
S d.p. = 2.1*0.4 = 0.84 m2
S v.s. = (2.5*13)-0.84 = 31.66 m2
Spl = 0.25*0.33 = 0.0825 m2
N = 31.66/0.0825 = 383.76 pcs., when rounded we get 384 pcs. For the stock of tiles, we take into account 5% and have 404 pieces.
How to calculate the number of tiles if two colors are selected
Let's assume that by design top part The bathroom will be lined with light tiles, dark ones will be located below, and they will be separated from each other by border elements. Now there is not one height, but three.
When calculating, the formula N = S/S pl is retained, but transformed:
- 1. N s.p. = S s.p./ S pl, N t.p. = S t.p./S pl, where
N s.p. , N etc. – quantity of light and dark tiles, in pcs.,
S.p. , S etc. – area of light, dark tiles, m 2
Spl – area of one light/dark tile, m2
- H St.V. = H-h 1 - h 2, where
H – room height, m
h 1 – height of the dark “bottom”, m
h 2 – curb height, m
For calculations you will also need the perimeter of all walls minus the width of the doorway:
- P = P v.s. - d, where
d – width of the doorway, in m
Number of top material(light tile):
P = 13-0.4 = 12.06 m
H St.V. = 2.5-0.9-0.08 = 1.52 m
S.p. = 1.52*12.06 = 18.33 m2
N s.p. = 18.33/0.0825 = 222.18, i.e. 222 pcs. Taking into account 5% - 233 pcs.
Number of bottom material(dark tile):
The calculation is similar to that of light tiles.
N etc. = 0.9*12.06/0.0825 = 131.56, i.e. 132 pcs. We add 5%, and in the end we get 139 pieces.
Number of border material:
N b = P/d 2, where
P – perimeter of all walls minus the width of the doorway, in m
d 2 – width of the border element, in m
Reminder! When choosing decorative elements, the number of required facing tiles decreases in direct proportion to the number of decorative units.
Calculating the laying of tiles in a diamond pattern
The amount of material for this type of installation is calculated by analogy with the standard method, only its reserve is not 5%, but 15%. The number of residues will be greater due to the cutting of the corners of the tiles at the junctions with the walls.
How to calculate grout for joints
When calculating the required volume of grout, you need to know the volume of space to be filled. Standard width the seam assumes 1.5-3 mm. A coefficient of 1.5 is applied to the seam depth parameter, which takes into account material shrinkage, humidity, etc.
The following formula is suitable for calculating grout:
V =((½ R pl /S pl)* T)*D*1.5*S total, where
V – volume of material over the entire area of the tile, in kg
Рpl – perimeter of one tile, in m
Spl – area of one tile, m 2
T – tile thickness, in m
D – seam width, in m
S total – total area of the tile, m 2
How to calculate the volume of tile adhesive
This is the simplest calculation of all the above, because... On the container, the manufacturer indicates how much mixture is intended for 1m2. To do this, it is better to first understand what layer of glue will be applied.
There is nothing complicated in calculating bathroom tiles. There are old proven methods that have been tested by time and experts. It is important to avoid mistakes when measuring room parameters and simple inattention.
Tile is the most suitable material for, but also quite expensive. Therefore, in order not to have to buy more or throw away excess, you need to correctly calculate the tiles for the bathroom, and for this we can use special or programs online calculation and layouts.
Correct calculation of tiles during repairs allows you to save not only time spent on purchasing missing materials, which, it should be said, may not be in the store, but also money that will be spent on surplus. And in order to avoid these troubles, there are several ways. A classic and accessible method for calculating materials on paper, and a more modern and convenient method - online tile layout.
But in each case there are certain nuances that need to be taken into account in order to calculate the material as accurately as possible.
The layout of the tiles is important in the further calculation of its quantity. Depending on the location of the seam between the tiles, there are several types of layout:
- Standard or basic (“seam to seam”).
- Diagonal, herringbone, labyrinth, bandaged, chess, run-up, carpet or modular layout, there are a great many options.
How to position the tiles correctly?
From an aesthetic point of view, it is important to consider the layout method, the location of the decor and color combinations in accordance with the area of the room. Finishing can visually change the proportions of a room.
In order to visually enlarge the room, use light-colored tiles, a horizontal laying method with a transverse placement of the pattern.
Options for laying out tiles in the bathroom
You can increase the height vertical layout, using contrasting stripes, vertical arrangement frieze, and in this case it is better to place the decodable elements slightly above eye level. Dark-colored tiles will visually make the room smaller. When choosing the color of floor tiles, it is important to consider that a dark floor and a light ceiling will visually increase the space, and vice versa.
It is important that the tile installation system is made with minimum quantity pruning. This will not only make installation work easier, but will also visually make the finish correct and more beautiful.
The trim on the walls is placed symmetrically between the corners. The pattern is laid out on the floor in such a way that solid elements are located in the visible area, and all trimming goes to the least visible sides or hidden under interior items. In matters of design, online tile layout will provide invaluable assistance, which will help create the most accurate visual model of the future finish.
Before calculating the tiles, it is important to take correct measurements of the room. It is carried out after the walls are prepared for laying tiles. Each side is always measured separately, even if the room correct form. Round the resulting value up. The size of the doorway and window is subtracted from the overall measurement. Sometimes areas that will not be finished, for example, hidden behind the bathroom, are also taken away from the total area.
We measure the area of the walls and floor
When the room complex configuration, has protruding elements, niches or boxes, their measurements are taken separately. It is better to record all the results by drawing up a plan of the room to scale, on which the location of plumbing fixtures, furniture and other interior details is noted. For a more accurate calculation, it is better to convert all numbers into millimeters.
Methods for calculating tiles
There is no single universal calculation scheme. In each individual case, everything depends on the specific layout of the room, the standard sizes of the tiles, and the layout of the tiles in the bathroom is taken into account. And depending on this, the most suitable of the three calculation methods is chosen.
- Sketch of the project;
- Calculations using the formula;
- Layout and calculation of tiles in the bathroom using computer programs.
Important! It is worth considering that in case of errors in calculations, it can be problematic to purchase additional tiles, because different batches of the same collection often have visible differences in shades, ornament geometry and some other technical parameters.
Sketching and piece-by-piece calculation of tiles
The most reliable results can be obtained by sketching the project on paper. For these purposes, any regular notebook sheet in a square or on graph paper will be suitable. The room is drawn to scale, each wall and floor separately. Mark the location of the tiles based on their size and installation method. Tiles of various shades, decorative elements, if they are used, the frieze is shaded with colored pencils for convenience. Such a project will allow you not only to imagine what the room will look like after finishing, but also to calculate the amount of material individually as accurately as possible.
Calculations using the formula
In this case, the amount of material is determined based on the size of the room and the material. Let's say you need to calculate the number of tiles to cover the floor standard bath. To do this, you need to know the total square footage of the bathroom, which is calculated using standard geometric formulas, for example: 1.73 × 1.73 = 3.46 m2, round the resulting number up, we get an area of 3.5 m2. Next, you need to find out the area of one floor tile: 0.335×0.335=0.112 m2. Next, we calculate how many whole tiles will be needed to cover the entire area: 3.5/0.112=31.2 pcs. We round the quantity to 32 and add 10% for defects and trimming, in the case of a diagonal layout - 15%. The total is 35 or 37 tiles, respectively.
This method is used if the layout of the tiles in the bathroom is standard, and individual elements do not differ in size. At in non-standard ways laying, the number of tiles can be calculated only by sketching the project to scale. Or through special services, if the program for laying out tiles suggests the possibility of such placement of finishing elements. You can be more precise about calculating tiles.
For walls
Wall tiles
As a rule, wall decoration is done in two shades, which are separated by a border, so first you need to determine the height of each layer. At the same time, it is better not to trim the lower dark layer, that is, its height will be a multiple of the height of the tile. Depending on the size of the tiles, lay out 3-4 rows. The height of the border will vary depending on the height of the tiles used for this. The remaining height of the wall is a light layer.
The dark band is calculated. The perimeter of the bathroom is multiplied by the height of the dark layer and its area is determined. The resulting number is divided by the area of one dark tile and its quantity is determined. Add 10% for pruning, fighting and rejects.
Light tiles are calculated in a similar way. The area of the wall for a light finish is divided by the already known area of one tile and the amount of ceramics is obtained light color. Add 10%.
The border elements are counted. To do this, the perimeter of the room is divided by the length of the border element. The part coming to the doorway is subtracted from the resulting number. Results are always rounded up to a whole multiple of one or a half, since halves are also used, for example, at corners.
For floor
Depending on the layout and configuration of the room, choose the most convenient method.
Bathroom floor tiles
By total area. They will find out total area floor of the room, without subtracting the box and niche, and divide it by the area of one tile. This way they will know how many tiles will be needed to cover a given surface. 10% is added to the resulting number, which will be spent on trimming and insurance against defects or damage to the material. The figure is rounded up to a higher value. The error with this method of calculation can be quite significant.
On both sides. First, find out how many tiles will be laid along each wall.
To do this, the length of the wall is divided by the length of the side of one tile that corresponds to it. The same calculation is carried out on the other wall and side of the tile. Thus, it is determined how many tiles are laid in one row along one and the other wall. The resulting figures are multiplied by each other, a margin of 10% is added and the total amount is obtained.
If the layout of the floor tiles in the bathroom is made diagonally, the calculation is performed in the same way, but it is recommended to add not the standard 10%, but 15% as a reserve.
Online calculator
You can also use our online calculator To calculate tiles, this calculator allows you to calculate not only the quantity but the cost of tiles.
Computer programs.
Modern computer programs make tile counting simple and convenient, provided you work with them correctly.
Programs for calculating bathroom tiles
Services that help with calculations can be roughly divided into two types: an online tile layout program and calculators for counting tiles. You can work in programs online or after installing them on your computer. Some of them are paid, but their functions and capabilities are significantly higher than those of the free versions. The tile calculation program allows the user to perform a number of actions:
- Lay out the tiles in a 3D model and thereby create a semblance of finishing the bathroom in the future;
- Calculate the amount of finishing material and tile adhesive consumption;
- In the programs, you can adjust trimming and select tiles from different collections.
Simplified versions for calculating tiles - calculators. These are small programs, usually online versions, that calculate material based on data entered by the user for already finished project. It is worth considering that using a calculator to calculate bathroom tiles is only possible if all finishing elements are the same size.
Calculation of the quantity of consumables
Tile tiles are usually laid on glue using a suture method, which means that for repairs you will need the adhesive mixture itself, grout, and installation crosses that will regulate the thickness of the seam; as a rule, you purchase only one package with a minimum quantity of 50 pieces. The consumption of a certain tile adhesive and the amount of grout are pre-calculated.
The consumption of tile adhesive is influenced by a number of factors, among which the most significant is the evenness of the base. Also, the thickness of the adhesive base increases depending on the size of the tile; the smaller it is, the smaller the layer of glue will hold it. For tiles use cement mixtures, dispersion adhesive or epoxy-based mixtures. They are inflicted notched trowel. Moreover, if its teeth are pointed, less glue will be required than when working with a spatula with square teeth.
In order to find out the approximate consumption of tile adhesive, multiply half the height of the tile by average consumption selected glue mixture and the area of the surface to be covered.
The best way to calculate is to use online calculators. They give out the most accurate results, based on data about the tile, base, tool, working conditions and selected adhesive.
Average material consumption using the example of Ceresit glue
Grout for joints
In order to calculate the required quantity, you need to know the volume of the space to be filled, but if the thickness of the seam is known, then difficulties arise in determining its depth. As a rule, it depends not only on the thickness of the tile, it is important to take into account the thickness of the adhesive mixture and what percentage of the grout will go under the tile. All these indicators are relative, so it will not be possible to accurately calculate the material. The amount of grout is taken based on its consumption indicated on the packaging and 10-15% is added.
You can also use our online calculator to calculate grout, which quite accurately calculates the material according to the specified parameters. The program algorithms calculate ideal values, so they recommend adding 10% to the result. (votes: 7
