When purchasing materials for renovation, you always want to know their exact quantity. On the one hand, this makes it possible not to overpay for excess material, on the other hand, to continue repairs without stopping for additional equipment. not an exception. Accurate calculation of tiles for a bathroom or other rooms will make the work easier and avoid additional costs.
The consumption of tiles for laying on the floor or walls can depend on many factors. Therefore, before planning the tiles for the bathroom, it is advisable to prepare properly.
What you need to know in advance
- what configuration will the material for installation be;
- how many colors do you want to use;
- will decor be used (borders, designs that require precise adjustment);
- how the installation will be done.
Each of these can significantly affect the amount of tile needed for a renovation. For example, laying out diagonally or increasing consumption means you will have to cut a lot.
And the choice in the catalog of monochromatic tiles color range and direct installation, on the contrary, will be more economical.
After you find the answers to these questions, you can begin calculating the tiles for the bathroom or any other room.

It's enough to just ask everything required parameters and the system will give you the total amount of material. This option is convenient when using complex patterns and styling methods.
To produce tiles manually, experts offer two options. Let's take a closer look at them.
Calculation by area
If you want to find out how many tiles you need this way, you will have to take the following measurements:
- measure the area of the base under tiles;
- measure areas where installation will not be carried out (doors, window openings);
- measure the area of one unit of material.
When all the parameters are found, it remains to make simple calculations. Namely, divide by the area of a unit of material, and, if necessary, round the number up. It is necessary to add 10–15% to the resulting amount of ceramics to compensate for the cost of trimming and scrap.
When the calculation is carried out for walls, you will first need to subtract the area of the doors and window openings, if they exist, and then divide the result by the area of one unit of coverage.
Piece calculation
This method involves a slightly different approach to calculations. And it's easier to explain in specific example. Let's say we need to make calculations for a bathroom with a floor length and width of 3 and 2 m, respectively. The size of the selected ceramics is 30x30 cm.
Divide the width of the floor by the corresponding tile value: 3/0.3=10. This means that the width will fit 10 pieces. We do the same with the length: 2/0.3 = 6.7. Round up to seven. This means that for one row in length you will need 7 pieces. Now let’s multiply these numbers: 10*7=70. This is exactly the amount of tiles that will need to be used for the floor of this room.
Such a calculation will provide more high accuracy, and is guaranteed to protect you from material shortages. But, when using it, it is worth considering one detail. If the required fragment for trimming is no more than 50% of the size whole tile, then from one piece you will get two of them. Accordingly, the total quantity will decrease slightly.
In numbers it will look like this:
- take a floor with dimensions of 2.5 m by 1 m and tiles 30x30;
- We count the number of tiles along the length - we get 8 whole and 10 cm for trimming;
- We count by width - 3 whole and 10 cm trimming;
- multiply the integers - 8*3=24 pcs.;
- We count the number of cut fragments:
- There are 8 of them in length, 4 in width (3 rows of whole ones + 1 of cut ones);
- let's sum it up - 8+4=12 pcs.;
Since the size of one fragment is less than half of one tile, two such pieces can be made from it. And, therefore, the amount of tiles for their production will be 2 times less. That is 12 pieces. divide by 2 and get 6 tiles per cut. We add them to those that will be stacked whole: 24+6=30 pcs. And don’t forget about the 10% to compensate for defects.
For those who want to save money and not buy material at a premium, this clarification will come in very handy. But it is advisable to do it only with a direct installation option.
In other cases, the probability of error is very high.
The principles of calculation are quite universal and are suitable for any surfaces, rooms, etc. And how to calculate the tiles in your case - choose for yourself. We hope that our information will help you with this.
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 floor surface. But this method is used only if it is planned to install seam to seam.
- the room is measured along the perimeter;
- take highest value 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 floor tiles - what are they 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 developed computer programs that allow you to calculate 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 the seller hardware store.
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 have to buy the missing amount desired color or the design will fail.

Correct calculation floor tile needs
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, calculate the consumption facing material it needs to be done 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);
- 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 corresponding mathematical formulas, or the floor is divided into simple geometric components (rectangles, triangles), the area of which must be calculated separately and summed up, 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.
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.
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.
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.
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. So how to spend money on buying a licensed full version impractical, it is best to seek help from a designer or a consultant at a hardware store. 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 won’t be able to find suitable tiles to purchase the missing quantity.
Tile is the most common finishing material, which is used for cladding not only internal but also external surfaces. He can withstand temperature changes and doesn't care high level humidity, but most importantly - ease of maintenance. Choosing this material for an apartment or house, the first thing you think about is: how to calculate how many tiles are needed in each specific case?
As a rule, most people initially purchase an approximate quantity depending on the cost required material(tiles, wallpaper, etc.). However approximate calculations lead to unreasonably high costs. The excess will simply gather dust in some corner, without bringing any benefit. In this article, we will try to do without this and make a more accurate calculation based on what exactly the tiles will be spent on.
Necessity of calculation
If you need to carry out repairs in your apartment or private property, you need to calculate everything correctly so that there is no excess. Some people believe that extra material is not a hindrance, but in reality everything is not so simple. During renovations, most people spend a considerable amount of money, and excess tiles lead to unjustified expenses. After all, hardly anyone wants to overpay for floor tiles?! In addition, its remains are usually not needed by anyone.
Often, having made an approximate calculation of the amount of material, you can find that there is simply not enough of it. All you have to do is go to the store and buy the rest you need. However, it's not that simple. The fact is that each batch produced has differences in shades. For this reason, in many stores, samples from the same collection have different prices. As a result of all this, you can see areas with different tones on the floor or walls, which somewhat spoils the overall impression.
In order to prevent the destruction of harmony in the design of the room, it is better to immediately make the most accurate calculation of the tiles. When choosing tiles for the floor or walls for your room, you should know its pros and cons, so as not to be disappointed later. You may need to give preference to another finishing material, who knows?!
Advantages of tiles
The popularity of tiles is difficult to underestimate or overestimate due to the obvious advantages of the material:
- tolerates moisture;
- does not fade in the sun;
- immune to the effects of aggressive environments;
- easy to clean;
- it can be used in low or high temperature environments;
- Relevant for a heated floor system in a bathroom or kitchen.
The tiles are available on the market in a wide variety of shapes and shades. Thanks to this, the material deservedly enjoys fame among professional designers. With it you can create original interiors, since the tile itself is already a good decor. In our modern times Every year, interior decoration is becoming more and more popular. At the same time, partial finishing is carried out not only in bathrooms and kitchens, as we are already accustomed to seeing. Living rooms also look good with elements of such decor.
Disadvantages of finishing decor
To solve the question of how to calculate how many tiles are needed for different surfaces, the shortcomings of the material should also be known in person. Compared to the advantages, there are not many of them. And one of them is a high degree of rigidity. On the one hand, this is even an advantage, but on the other hand, dishes that fall on the tiled floor will inevitably break. Also, due to this quality, serious difficulties arise when cutting tiles. Particularly for materials with a glazed surface.
In addition, enameled and polished tiles are quite slippery. Fortunately for most renovation lovers, all these existing shortcomings are not so serious, so now you can safely move on to directly studying the calculation of the required number of tiles.
Features of calculation of facing material
How to calculate the number of tiles? There is no universal option or special formula in this regard. Some may immediately object that it is enough to know the area of the room. In reality, not everything is as simple as it might seem at first glance. It is important to take into account the condition of the floor, what the final version will be, and the dimensions of one tile sample. It is also important to consider whether the pattern will be created, the method of laying the tiles and what kind of surface: floor, walls, backsplash (usually in the kitchen) or bathroom (in whole or in part).
Let's try to figure this out difficult issue. By making the calculation using the methods described below, you can determine the net amount of tiles. However, during the work it will need to be trimmed, and therefore it is worth adding another 10-15% to the result obtained. This is an error that is inevitable - the material will break when cutting and the like.
Number of tiles per floor
How to calculate the number of tiles for the floor? The dimensions of the room and the tile itself should be taken as a basis. In this case you can use different ways. For example, let’s take the average dimensions of a room, which is typical for most residential buildings: length - 3 meters and width 2 meters. For calculation, it is better to reduce all known ones to one form: length - 300 cm, width - 200 cm, tile dimensions - 20 x 15 cm.
To begin with, you can determine the area of the floor in the room and one tile. It's not that difficult - the length is multiplied by the width (the answer is 60,000 cm 2 and 300 cm 2, respectively). Now you need to divide both values among themselves, the result will be the amount of material. That is, Q=60000/300=200 (pieces). If the answer is fractional, it must be rounded up, for example, 63.35 = 64.
You can divide the length of the floor by the same parameter of the tile (the answer is 15 cm). The same thing with the width - 200 divided by 15 and we get 13.33. All that remains is to multiply the obtained values among themselves and calculate Q = 13.33 * 15 = 199.95, but taking into account rounding - 200 pieces. Taking into account the error - 220-230 pieces, no less.
Calculation of tiles on the wall
How to calculate tiles for a wall? Here everything is somewhat more complicated. If tiles of the same color are laid on several walls (or on all 4 as when tiling a bathroom), then the calculation can be carried out as with the option for the floor. First, the number of tiles is determined in relation to one wall, and then to the other, and so on. At the end, the results obtained are summarized, not forgetting to add 10-15%. Only when taking measurements of the walls, it is worth excluding the area of the interior passage, as well as all other places where there will be no tiles.
It’s another matter if you need to lay out some kind of pattern or ornament from the tiles, as you like. Here it’s worth mastering the designer’s specialty a little, armed with a pencil and a piece of paper on which to draw up a rough drawing on which the entire pattern and the location of each tile will be clearly visible.
To begin with, it is worth carrying out a standard calculation of wall tiles with a pattern for one of the walls. That is, measure its height and divide by the length of the tile. For example, the height of the room is 250 cm, and the length of the tile is 30 cm. As a result of division, we get the answer - 8.3, which we round up to 9. That is how many horizontal rows there will be.
Next, we take into account the length of the wall (or width), for example, 300 cm (200 cm). Suppose we put square tiles and therefore its other parameter is also 30 cm. Now we calculate the number of vertical rows and as a result of the calculation we have - 10 (20). Now we multiply these two values: 9*10 (20) = 90 (180).
Now is the time to refer to our drawing and count how many tiles are of a distinctive color. Then this number is subtracted from the total calculated quantity.
How many tiles are needed for a bathroom?
In fact, determining the amount of tiles for a bathroom is practically no different from the examples given above. Here it is also necessary to measure the height and length (width) of the walls. Usually such premises in many residential buildings are made regular square or rectangular shape. In this case, if it is a square, it is enough to measure the parameters of one of the walls, and then multiply by 4 during the calculation. For a rectangular room, you already need to measure two walls, and again need to multiply by 2.
Sometimes it is difficult to calculate how many tiles are needed for a bathroom. The fact is that the interior of some rooms is complicated by niches and protruding elements. Then you will have to separately measure each surface on which the tile will lie.
The obtained values should be written down, but for greater convenience it is better to plan the room. At the same time, indicate the location of plumbing fixtures, furniture and other elements. This will allow you to more accurately determine how much material is needed and minimize excess.
Usually during the calculation it is necessary to exclude some areas. For the bathroom this is the doorway. There is also no need to lay tiles under the bathtub, since this part of the walls will not be visible. Especially when installing a screen, which will allow you to save a little on material. Therefore, measuring the height of the surfaces to which the bathroom adjoins should start from its sides.
Counting tiles for backsplash
How to calculate tiles for a backsplash? Typically the dimensions of this area, minus wall cabinets and the allowance for the table top is 55-75 cm, which corresponds to the standard. However, in some cases, this working area of the kitchen may have different dimensions.
To determine how many tiles will be used for the apron, you must first find out whether it will be made for the entire length of the wall or not.
If the furniture is already present, then you need to measure the necessary parameters:
- the height of the bottom row of cabinets with table top and legs (if any);
- height of the top row of cabinets;
- If you have a pencil case, you will also need its height.
In addition, it is also worth taking into account the height of the hood, which is usually 72 cm from the countertop, and its allowance, which is another 10 cm. It is also necessary to retreat from the apron by 3-5 cm in order to hide its edge behind the set.
If there is no furniture yet (if major renovation or for a number of other reasons), you should mark two boundaries on the wall below and above. The first is a line of floor cabinets, and the second is the bottom edge of wall furniture. Lines must be drawn evenly using a level to the required length. This will allow you to more clearly and accurately solve the question of how to calculate how many tiles you need.
In any case, you will end up with a rectangular section, the length and height of which must be measured to calculate the area of the apron. If the plot is corner, then calculations are carried out from each of the walls, and then the two results are summed up. You also need to calculate the area of the tile.
Now all that remains is to divide the calculated value of the apron by the area of one tile, thus determining their total number. Just don’t forget about the 10% reserve. A fractional number rounded up.
Diamond laying
This method of laying tiles on the floor or walls looks more prestigious and harmonious. How to calculate is already known - determine the area of surfaces (walls, floors) and tiles. Then divide the received data among themselves. For example, the floor area was determined to be 7.5 m2, and the tiles - 0.09 m2. Then the result will be: Q=7.5/0.09=83.33, taking into account rounding we get 84 pieces.
The tiles need to be laid from the center of the surface to the periphery; the size and shape of the tiles should also be taken into account. In addition, you will need to trim the edges, which increases material consumption. For this reason, the reserve will already be 15-20%. That is, in the end we have 97-100 tiles.
Finally
As you can see, calculating the required amount of facing material is not as difficult as many people think. And to facilitate the whole process or when you are too lazy to carry out all the calculations yourself, there is a convenient option - an online calculator. All you need to do is enter the required data. Therefore, measurements will still have to be taken.
You can also contact a specialist who will calculate everything on the spot within half an hour. But at the same time, you will have to part with some money, and also listen to a professional opinion that it is better to entrust the installation to specialists. Perhaps even from the company where he works.
But if only a person experienced in this matter can really handle laying tiles, then each of us can solve the question of how to calculate how many tiles are needed. After all, we all went to school, at least most of us.
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 shapes, find the area of each of them and sum up 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.
Have to take notebook sheet in a box, or a sheet of graph paper, determine the appropriate scale of the room, 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.
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 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 total height 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.
