How to calculate the number of tiles in a bathroom calculator. How to calculate how many tiles you need - methods for all types of cladding. Required quantity of floor tiles

Sometimes it is very difficult to imagine what your bathroom will look like after renovation. Many people, due to their way of thinking, are not able to see a tile and imagine how it will look in the room. Of course, you can look at the interior options offered by the manufacturer's designers and do one-on-one... But this option is often not suitable, since the premises are designer interiors rarely coincide in size and shape with real, standard bathrooms.

How to understand whether this or that tile will suit you or not? Option one is to arrange a meeting with the designer in one of the stores. Using specialized programs, a virtual tile layout will be created according to your dimensions. Of the minuses - you will have to buy tiles in this store, you will spend a lot of time with the designer, because... people rarely understand each other from the first word. And the more tile options you consider, the more time you will spend.

The second option is to learn how to work with tile layout programs. Unfortunately, the programs are entirely paid, and learning them can take a lot of time.

The third option is to use our service to lay out the tiles yourself. It is absolutely free, it allows you not only to visualize color combinations tiles, but also calculate in detail the required quantity, taking into account the savings on cutting tiles. We will tell you how to lay out tiles in this service on this page.

To create a layout you will need:

  • Dimensions of all walls in the room
  • Doorway size. If the door is installed, then to the width door leaf you need to add 10cm to the height of 5cm.
  • Bath size. The length is usually equal to the length of the wall to which the bathtub is adjacent. Width and height are also needed. The height of the bathtub is usually adjusted with legs, so you need to decide on the desired height.
  • Tile collection.

Start creating a layout

Go to the page of the collection whose layout you want to create. Find the “Create Layout” button on the page and click it. The tile layout creation program will launch.

Appearance

At the top there are tabs on which control and settings buttons are grouped.

Room parameters

On the Room Settings tab, click the button. A dialog box will open allowing you to enter room size settings. Please note that changing these settings will reset all entered data. Therefore, you need to enter them at the very beginning of working with the layout service. When you enter the dimensions of a room in the work area, the walls of the room will be displayed in accordance with the entered dimensions. After setting the dimensions, use the zoom buttons to increase or decrease the scale of the layout to fit the screen size to comfortably continue working with the layout.

Installing objects

On the "Objects in the room" tab you can place a bathtub, sink, mirror, door in your room. When you click on the icons depicting an object, a dialog box will open for entering the dimensions and position of the object in the room. The input results will be displayed in the layout work area.

Tile laying grid, installation of borders, mosaics

On the "Tiles" tab, you can shift the tile layout grid, change the layout direction (vertically, horizontally), install borders and mosaics. The cell size of the layout grid is automatically calculated based on the size of the base tile.

  • Layout direction (vertical or horizontal)

    The tiles can be laid both “lying” and “standing”, if the design of the decorative elements and the size of the borders allow it. To change the direction of the layout, click with the mouse on the image of the wall on which you want to change the direction of the layout, and then click on the first button in the row with the image of two arrows. If the laying direction needs to be changed for all walls, then do this operation for each wall.

  • Grid shift, first tile size, end tile size, cropping control

    Beautiful tiling involves trimming the tiles evenly on the left and right sides, centering decorative elements, adjusting the seams to the height of the bathtub, and much more. You can do all this by activating the wall by clicking on its image, and then using the buttons with arrows (). The direction of the arrow indicates in which direction the layout grid will be shifted. The shift step is 1 cm.

  • Borders and mosaics

    Curbs are narrow decorative elements, usually installed for a harmonious transition between tiles of different colors, as well as for zoning a room. Installation of borders within one wall should be the entire length or height of the wall, otherwise the geometry of the tile layout will be shifted, which is extremely unsightly. Installation of borders is done by pressing the button with the image of two solid vertical (for vertical, ) or horizontal lines (). When you click the button, a dialog box opens in which you first select the number of the wall on which you want to install the border, then select the border from the list of available borders, and then use the up and down arrow buttons to move the row with the border higher or lower. When installing a mosaic (buttons and ), it is possible to set the width of the mosaic row.


Laying tiles

On the "Layout" tab, you install the tiles on your walls, edited in the previous steps. More information about the capabilities of this step and controls:

  • Changing the seam color

    For improvement visual perception layout You can change the color of the tile joint. To change, click on the "Seam Color" button and select the desired color in the dialog box that opens. Unfortunately, the grout color cannot be changed for individual rows or tiles. You will immediately see the resulting result in the work area.

  • Wall background color

    To improve the visual perception of the display, you can change the background color of the walls. For example, when the tile has a single color grey colour, it's hard to see places where you haven't installed tiles. By changing the background color to a darker or lighter one, you will immediately see empty areas of the layout. To change, click on the "Background Color" button and select the desired color in the dialog box that opens.

  • Selecting tiles for installation

    To select the tile you want to lay out, click on the "Select Tile" button. A dialog box will open in which the tile images will be located. For convenience, the tiles are divided into tabs with the names of tile types - Regular (basic, background) tiles, Decors - tiles with a pattern, and Panels - sets of tiles with a pattern, together forming a complete pattern or composition. The tile is selected by clicking on the image. The selected tile is displayed at the top of the service.

  • Rotate tiles 180 degrees

    In some cases, it is necessary to accurately indicate the direction of laying tiles with a pattern in order to beautifully join their pattern. To do this, there is an option to flip the tiles 180 degrees. At the top of the service there is a checkbox with the inscription “Flip” (a field for placing a checkmark/bird). With this option enabled, all installed tiles will be flipped 180 degrees relative to their image.

  • The process of installing tiles on walls

    Once you have selected a tile, simply move your mouse over the wall where you want to install the tile. IN in the right place click the mouse, the tile image will be installed in this place. To cancel the installation, click in this place again - the tile will be removed.

  • Reflection of calculations

    In addition to visually displaying the location of tiles on the walls, the service also calculates the number of tiles used. Moreover, if, depending on the browser settings, there is a possibility of slight distortion of the picture, then the calculations are entirely based on the mathematical calculation of the coordinates of each object. You can view the calculations by clicking on the "Show calculations" button in the upper right corner. The results will be displayed in a summary table below the wall images. The table contains information on the number of whole tiles (C), cut vertically (Pv), horizontally (Pg), cut in two planes (Pvg), the area of ​​actual laying, and the required quantity for laying.

    When calculating the required number of tiles, based on the optimal algorithm for the consumption of scraps, the number of whole tiles for laying is calculated (in other words, the laying of scraps without overspending is taken into account). If tiles are cut in two planes, the trimmings are considered unsuitable for use.

    You can independently check the correctness of the calculations by clicking the mouse in the calculation table in the cells with the number of required tiles - the tiles on the walls will be marked with a red fill. Clicking again will remove this fill.

Ask a question - get an answer!

To begin with, it is worth noting that the correct calculation of tiles for the bathroom is the key to successful, quick and quality repairs premises. It is for such cases that a special program for bathroom tiles has been developed, thanks to which you can avoid unnecessary costs associated with the purchase of unnecessary materials.

Variety of programs

The bathroom tile calculation program is an excellent solution for correctly calculating all repair aspects. Today, you can calculate bathroom tiles using a huge number of different programs, which we will introduce you to below.

When choosing a program, pay attention to the number of options and functions that it has.

A bathroom tile design program should include:

  • selection of tiles for the bathroom;
  • calculation of the required amount of tile solutions;
  • selection of the most suitable shade of tiles, their texture, as well as parquet and wallpaper.

Today, the most common programs are “Tile”, “Arculator”, and “3D Tile”. Using the programs is very simple - you just need to enter the initial data, after which you will receive the required number of tiles.

Tile calculation program "Tile"

For example, the “Tile” program today has many versions - it is used in tile salons. The program is intuitive, has simple navigation and control, you can easily create a three-dimensional model of your room based on real dimensions, taking into account windows and doors, plumbing and other elements.

“Arculator” is an original program that will not only calculate tiles, but also help lay linoleum, laminate, and make suspended ceilings.

Everything here is not as bright as in the “Tile” program, but “Arculator” calculates more accurately, so you will receive the most detailed calculation.

Some latest versions programs will also help you choose tiles for the bathroom, taking into account the lighting of the room, as well as its dimensions. The latest option, which allows you to design the entire design of the room, is the 3D layout of tiles in the bathroom. Laying out tiles in a 3D bathroom not only allows you to place the position of the future covering, but also makes an accurate calculation of all materials and indicates their average cost. In addition, 3D calculation of bathroom tiles allows you to look at the already finished room in a three-dimensional image. Thanks to this, we can notice and correct all the defects that we encounter when modeling tiles in the bathroom.

Bathroom tile layout 3d

Here it is worth noting the ViSoft Premium program - this is an excellent way to design a bathroom with precise dimensions - taking into account all the plumbing fixtures and furniture. The program allows you to plan the little things - everything in order to minimize the cut tiles, calculate the cost very accurately and create plans for the room and tile laying, in particular. This program for visualizing bathroom tiles is designed exclusively for advanced users, so they are mainly used by specialists from construction companies.

Self-planning

You can also carry out precise design of bathroom tiles yourself. The work is quite simple and does not require a huge amount of time.

There are a sufficient number of ways to calculate the required amount of consumable materials.

We will describe to you the simplest of them - planning the tiles in the bathroom using them will help you create the ideal room.

Laying out tiles on the bathroom floor

For this method of calculation, it is necessary to measure the surface area and dimensions of the tile. For example, the size of the bathroom is 2 meters by 2, and the tiles are 20x20 cm. In this case, the area of ​​1 tile is 0.2 * 0.2 = 0.04 m. That is, the number of tiles is 2/0.04 = 50 pieces .

To do this, you need to measure the height of the room - 2 meters, the length of all walls 2.5 + 2.5 + 2.5 + 2.5 = 10 m and determine the dimensions of the tiles 0.2 * 0.2. Next, divide the perimeter of the room by the width of the tiles 10/0.2 = 50 pieces. We do the same for a height of 2/0.2 = 10 pieces. Next, multiply the result 50*10=500 pieces. The final stage is to convert the number of tiles into square meters; for this, the number of tiles is multiplied by the area of ​​one piece. 0.2*0.2=0.04. 0.04*500=20. In total we get 20 square meters of tile material.

As you can see, modeling bathroom tiles yourself is a very simple method, accessible even to non-professionals. We would like to draw your attention to the fact that to the results obtained it is worth adding 10-15% of the material to stock the tiles in case of unforeseen situations.

You can also use the tile calculator on the website.

Counting the grout

After laying the tiles on the wall surface, the main thing that needs to be taken care of is the grouting of the joints between the applied tiles.

When preparing grout, the main thing is to correctly calculate the required amount, and for this you need to calculate how much volume will need to be filled.

The optimal seam width ranges from 1.5-3.00 millimeters, no more, but no less. Plus, to the depth of the seam, which will be approximately equal to the full thickness of the tile, it is necessary to apply a coefficient of 1.5 millimeters. This will help when taking into account tile shrinkage, room humidity and much more.

When calculating how much grout will be needed in a particular case, you need to divide 1/2 of the tile perimeter by its full area, and then multiply by the height of the tile. The result obtained must be multiplied by the width of the seam and by the coefficient. The result will be the required volume in kilograms of grout that will be needed for one full square(square meter) coverage. For example, if the area of ​​the tile is approximately 0.04 square meters, and the joint width is about 2.00 millimeters, then one kilogram of grout is enough for an average of 3.5 square meters.

Calculator

We would also like to say a few words about special calculators for calculating tiles. The calculation calculator is another designer of bathroom tiles. They were developed to simplify calculations for construction companies. The calculation is as follows: measure the area of ​​the room, divide the result by the area of ​​the tile. The result obtained from such calculations is presented in meters.

In this article we introduced you to different ways calculating the required amount of tiles, the most optimal of which is the program for laying tiles in the bathroom.

Typically tiles are sold in square meters. For order floor tiles It’s enough to know the square footage of the room: if your kitchen area is 10 square meters. meters, then you will need to order 10 m of tiles + a reserve for trimming and breaking (usually around 10 percent).

However, sometimes you want to imagine exactly how many tiles will go for each meter. If you just want to imagine this number in order to visualize the picture (how many tiles will go per meter: 4, 10 or 20 tiles), then this is very easy to do. If you need to calculate the exact number of tiles in pieces that you will need to buy in order to lay out a square meter in your room, then this is a little more complicated. (These two values ​​may be slightly different, yes)

Let's start with the easy one: how many tiles per square meter(any meter, completely abstract)

Calculating the area of ​​the tile

First you need to calculate the area of ​​one tile in square meters. For this her length(in meters) needed multiply by width(in meters). It is better to multiply in meters rather than in centimeters, so as not to get confused with the conversion of square centimeters to square meters)

For example, let's take a tile measuring 20x20 cm. Since there are 100 centimeters in one meter, 20 cm is 0.2 meters (20/100 = 0.2). Multiply the length by the width 0.2m x 0.2m=0.04 sq.m. Thus, a 20x20 cm format tile has an area of ​​0.04 sq.m.

If the tile measures 30 cm by 60 cm, the calculation gives 0.3 m x 0.6 m = 0.18 m2. For a tile 12.5 cm x 120 cm, the area will be 0.125 m x 1.2 m = 0.15 m2.

Counting the number of tiles

Knowing the area of ​​one tile, it is enough to divide 1 square meter by this area to get the number of tiles. For a 20x20 cm tile, the calculations will be: 1m2 / 0.04m2 = 25. Thus, there will be exactly 25 20x20 cm tiles per meter.

For a 30x60 cm tile the results will be 1/0.18 = 5.555(5). About five and a half tiles.

Number of tiles per meter for popular sizes (with slight rounding))

Tile 10x10 cm - 100 tiles per square meter
Tile 15x15 cm - 44.44 tiles per square meter
Tile 20x20 cm - 25 tiles per square meter
Tile 20x50 cm - 10 tiles per square meter
Tile 25x50 cm - 8 tiles per square meter
Tile 25x55 cm - 7.27 tiles per square meter
Tile 30x30 cm - 11.11 tiles per square meter
Tile 30x56 cm - 5.95 tiles per square meter
Tile 30x60 cm - 5.55 tiles per square meter
Tile 33x33 cm - 9 tiles per square meter
Tile 40x40 cm - 6.25 tiles per square meter
Tile 45x45 cm - 4.93 tiles per square meter
Tile 50x50 cm - 4 tiles per square meter
Tile 60x60 cm - 2.77 tiles per square meter

It is important to understand that this value is approximate, calculated. In reality, another number of tiles may be needed per meter. Let's see why.

Let's say our room measures one meter by one meter (that is, the same square meter of area), and the tiles measure 30x60 cm. According to preliminary calculations, we needed 5 and a half tiles, right? In reality, we may need 7 tiles

Why is this happening? Because in the calculations the entire area of ​​the material is considered as a whole, as if we had poured it or laid it in tiny pieces. If desired, of course, the scraps from tiles 4, 5 and 6 can be used to cover the area of ​​the seventh tile. This is quite enough, as calculations show. But the length of the remaining pieces is shorter than needed (they are 20 cm each), so it will all look questionable.

Bad news, we'll probably need eight tiles. We want the tile to look beautiful, small pieces are not very aesthetically pleasing, so we’ll align it in the center.

Well, you may decide that the whole problem is that we took a large tile of the wrong size (30x60 cm) for such a small area (1 square meter). Nobody does this, you have to take a small tile. Okay, let's take a 10x10 cm tile. What can happen to it? It would seem like nothing. Exactly 100 pieces of such tiles fit in a square meter (1/0.01=100).

Well, no.

The fact is that a square meter is not necessarily a square room measuring one meter by one meter. It could be narrow corridor measuring 2 meters by 50 cm. What's worse, it could be a passage with the exact dimensions of 57 cm by 1.76 m. Multiple sizes of 10 will instantly give us waste. As a result, the area will require 108 tiles. 18 horizontally, 6 vertically.

Of course, as the footage increases, the percentage of extra tiles usually decreases. In any case, before calculating the number of tiles, decide for yourself for what purposes you need it: just for guidance or for ordering. If you are ordering and you want to count the number of tiles accurate to the piece, you cannot divide the area of ​​the room by the area of ​​the tile. You need to either draw and look, or divide the length of the room by the length of the tiles, the width by the width, and decide how you can combine the remains.

Finishing a bathroom is a complex process. In addition to technological subtleties, there is also a problem with design. Baths, toilets, and combined bathrooms are usually tiled. But how to plan its placement on the walls so that the finish is beautiful? For those who decide to do the repairs themselves, there is a good solution - to use software. There are special programs for laying out tiles, there are such sections in general construction or design software, and there is also an online service from large manufacturers and stores selling finishing materials. They will be discussed further.

Tile 6.0

Specialized program for laying out tiles and wallpaper. There are three versions: Home for home use, Profi - for professionals, Profi+Render - professional with advanced functionality. For self-creation The design is suitable for Tile 6.0 Home, but it is not free - 1000 rubles per month of use. All of them can be purchased on the campaign website tile3D.com. Naturally, there are hacked copies, but it’s difficult to say how safe it is to download them.

The program in its current version is good: even the stripped-down home version allows you to create three-dimensional projects (3D) and receive calculations based on necessary materials(in addition to whole and cut tiles, he counts the amount of glue and grout for the seams). What else can she do:

  • Take into account door and window openings, columns, arches and other curved surfaces.
  • It is possible to add new tiles to the directory and save them for future use.
  • Tiles can be installed and moved at any angle.
  • You can add three-dimensional images of other objects (bathtub, shower, etc.) by specifying their coordinates.
  • The program calculates the tiles and Supplies, but in the “home” version you cannot print them, but you can copy them from the screen or take a screenshot and print them as an image, not a table.

In addition, you can change the degree of illumination, shine and relief of the tile. All these settings can be made for each individual object. What’s also good is that the site has educational videos on how to use the program, where the creation of a project is described step by step. Working in the program is easy, the interface is clear, and you can master it the first time. One of the disadvantages of the home version is that you cannot get a scan along the walls, which is completely inconvenient. In general, the program is good, but not free.

ViSoft Premium

This is specialized bathroom design software for professionals. One of the functions is tile layout. The database contains a large number of samples - almost 39 thousand types of tiles from different manufacturers (at the time of writing there were 362). The layout project is developed based on the samples that are in the database; new ones cannot be added.

Here is a summary of the program's capabilities:

  • Selected tile samples are automatically placed in the specified area.
  • It is possible to view other layout options.
  • To create a bathroom interior, you can choose plumbing fixtures from a huge database. In this case, the sets are compiled automatically. If necessary, they can be adjusted.
  • During the creation process, the project can be turned in any direction, evaluating the result from different points.
  • Take “snapshots” of the results obtained.

There are two operating modes: drawing and sketch. In drawing mode, a black and white image is created, which can later be “filled” with different colors. Sketch mode - immediately with color.

Ceramic 3D

Good professional software for creating bathroom designs. Naturally, it is not free, but there is a demo version with full functionality that is available to everyone without payment. The free license is valid for 1 month. If you decide to lay out the tiles for yourself, this is a good option, but you must meet the specified deadline.

The Ceramik 3D program is available in a demo version for a period of 1 month, it is free

Ceramic 3D allows you to quickly create projects: each operation takes about 2-4 seconds. So simple projects are “built” in 5 minutes, complex ones require 15-20 minutes. Here is the set of functions:

  • creation of premises of any configuration according to exact dimensions, including attic ones;
  • easy drawing of niches, shelves, ledges, boxes of any configuration;
  • the ability to create a tile outline of any shape (polygonal, round, etc.);
  • drawing of columns and their decoration;
  • saving styling patterns of any complexity;
  • replacing the contours and dimensions of the room while maintaining the layout;
  • the ability to create stairs and decorate them with tiles;
  • automatic calculation of the number of tiles.

In general, Ceramic 3D is not only a program for laying tiles. In it you can create the overall design of the bathroom and work out the design of other elements or parts of the room that involve laying tiles. It’s nice that the program comes with detailed lessons that make it easy to master.

Compass-3D LT

This is a free version of a professional program for three-dimensional design of various objects and parts, created by Russian company ASCON. So it's not just a tile layout program. This is just one small part of it. The Compass-3D LT version is an introductory version that allows you to master volumetric modeling and planning. The program comes with training materials - videos and graphic examples.

The 3D compass in its lightweight version has very limited functionality, but it is more than enough for laying out tiles. To plan the layout of the tiles during installation, a package with a construction configuration is downloaded (there is also a mechanical engineering configuration). The basic and building packages require approximately 3.5 GB of disk space.

With this program you can:

  • make a site plan;
  • develop a room design using various finishing materials and evaluate the result in the form of a three-dimensional picture;
  • develop unique decorative items and obtain their drawings;
  • upon completion of the project, receive drawings indicating dimensions.

In general, the program is multifunctional even in the free version. At the same time, you can master the basics of 3D design.

A simple program for laying tiles without special effects - Arculator 7

If you do not need a three-dimensional image, but just need to look at the layout, and even calculate the amount of material without errors, pay attention to the Arculator 7 program. It is designed for calculating materials for internal finishing works. That is, with its help you can accurately determine the required amount of tiles, wallpaper, laminate, etc. It is also possible to calculate the amount of materials for ventilated facades. A pleasant surprise: this program for laying out tiles (and more) is free.

What you can do in it:

  • Create surfaces of any size and shape, place openings of any shape on them.
  • The position of the tiles can be adjusted and rotated at any angle.
  • Objects can be located on one surface different sizes in different directions.

Learning how not to work is not a problem even for the least “advanced” user. The interface is clear, the computer requirements are very modest, it takes up less than 1 MB of disk space. Great option, if you only need a layout, and not a design development with the arrangement of plumbing fixtures, furniture, etc.

What else can you work with?

In addition to specialized programs, there is a lot of software designed for planning other objects, but which have sections for laying out tiles. If you have experience in one of them, it will be easier to work with a familiar interface than to master a new one. Here are some general construction or furniture programs in which you can draw tiles.

  • AvtoCad (AutoCad) is a general construction program with wide functionality (2D and 3D available).
  • NanoCad is an analogue of the one described above, but it is a Russian development. The basic version is free.
  • PRO100 (PRO100). The program is designed for the design of furniture, but there is a solid section for designing the layout of tiles, laminate, and wallpaper. Many people say that it is easier to work in it than in AutoCad.
  • SketchUp is a program for designing rooms and furniture; there is a section for tiles, but the functionality is limited and difficult to work with. In addition, you have to manually recalculate the quantity as errors in calculations are common.

Of course, this is not specialized software and it is not so convenient to work with them. But if you have already worked on them in other sections, it will be easier and faster to understand than learning to design in a new program.

Online tile layout programs

Most large online stores selling tiles or manufacturers provide the opportunity to create your own project online for free. The peculiarity is that basically you can only work with those collections that are on the resource. You cannot enter your own data into such programs.

They work on the principle of browser games—no need to download or install them. You work through a browser on the campaign resource. The procedure for creating a project is standard: you select or draw a floor plan for which you need to create a tile layout, select a collection (from those that are on the site), then create a layout. Based on the results, a list is usually generated: how many tiles are needed, you can also print or save the layout that you made in the form of a scan along the walls.

In order to calculate the amount of tiles for the bathroom, you first need to decide on the following questions:

  • What type of installation will you use;
  • Which color scheme you plan to apply;
  • Will it be necessary to adjust the drawing;
  • Will you lay only tiles on the walls or add decorative elements to the decoration?

Selecting the installation type

Floor

When working with flooring material The following types of installation are commonly used:

  1. standard - when the edges of the tiles are laid along the walls;
  2. diagonal – the edges are laid at an angle of 45 degrees;
  3. diagonal checkerboard - when laying ceramics of different colors, they alternate.

Walls

When laying wall ceramics, you can choose the following types of cladding:

  1. ordinary “straight” - when the elements are laid parallel to the floor;
  2. regular with borders (one wide or narrow and wide, alternating);
  3. diagonal;
  4. checkerboard (regular direction or diagonal).

The choice of laying type is important, because with a diagonal direction, material consumption increases, because you will have to do a lot of trimming of the corners of the tiles to fit from the center to the corners of the walls.

When fitting to a pattern, you will also have to do a lot of trimming of the edges.

And it is also necessary to take into account that it is better to make the joints of the first rows away from the walls so that possible unevenness of the wall is not noticeable.

General calculation rules

Exist general rules How to correctly calculate the amount of tiles, whether for the bathroom or for other rooms where you decide to lay tiles.

  • measure (in centimeters) the length and height of each wall on which you will lay tiles, and the length and width of the floor;
  • from the dimensions of the wall in which it is installed Entrance door(or which has a bathtub) subtract the dimensions of this door (bath);
  • decide on the size of the plates that you will lay (on the floor - 30x30, 33x33, 40x40 cm, etc.; facing - 20x30, 25x33 cm, etc.);
  • Preliminarily calculate the result in square meters, and to clarify it you will need to count the number of tiles individually.

Moreover, keep in mind that the required amount of building materials must be immediately increased by 10%, because such a reserve will be required for trimming at the edges of the walls, in case of careless damage to the tiles or cosmetic repairs some section of the wall (floor) in the future.

When calculating the number of tiles, it is better to immediately do without an online program, because no matter how perfect it is, it still allows for errors. For example, it does not take into account the width of the seams between the rows, and its postscript still recommends checking all the results manually.

Laying tiles on the floor: calculation example

In order to make a specific calculation required for laying on the floor, we take the following data as the initial data:

  1. Floor width – 150 cm
  2. Length – 170 cm
  3. Product size – 33x33 cm

Standard installation, tiles of the same color

  • To find out how many tiles you need, first divide the width of the floor (150 cm) by its side (33 cm), we get the result - 4.54 (the number of tiles in one row in width), round to the nearest whole - 5 pieces.
  • Now let’s calculate how many such rows are needed along the length of the bathroom: divide 170 cm by 33 cm, we get 5.15 rows, round up to 6.
  • Next, we multiply 5 tiles in one row by 6 rows, we get 30 pieces. We add 2-3 in reserve, and that means we will buy 33 ceramic tiles.

If the calculation of the number of tiles had been made not by piece, but by floor area, then a serious mistake would have been made. Floor area – 1.70m x 1.50m = 2.55 sq.m, divided by the area of ​​one tile 0.33m x 0.33m = 0.11 sq.m, we get 24 (rounded) pieces. That is, 6 tiles (plus extra) would not be enough for the floor. After all, the piece count actually took into account the cutting of the plates during laying.

Bathroom wall cladding

  • 270 cm (wall height) divided by 30 cm (tile height) = 9 elements in one row in height.
  • 150 cm (surface width) divided by 20 cm (product width) = 7.5 – round up = 8 pieces in width.
  • We multiply 9 by 8, we get - 72 units measuring 30x20 cm are needed for one wall 150 cm wide.
  • Using similar calculations for a wall 170 cm long, we get the result - 81 tiles.

Taking into account the doorway

To calculate the amount of tiles required for cladding the wall in which the door is installed, it is necessary to subtract the amount that corresponds to the dimensions of the doorway from the number of elements for the opposite wall.

For example, divide 200 cm (the height of the doorway) by 30 cm (the height of the tiles), we get 6.7 - round down = 6 pieces in height; Divide 70 cm (the width of the opening) by 20 cm (the width of the product), we get 3.5 - round down = 3 pieces in width. We multiply 6 by 3, we get 18 pieces, which we subtract from (for example) 81, we get 63 pieces.

If you will completely cover the wall next to which the bathtub will be installed, then it is easy to calculate the number of tiles on it. If you do not plan to tile the space occupied by the bathroom, then the calculation for this wall is carried out similarly to the calculation for the wall with a door.

Calculating the amount of grout

After completion of the installation work, the joints are grouted. To do this, use grout that matches the color of the main color of the coating, or a contrasting one (white for black tiles, etc.).

To calculate the amount of grout for tiles, you need to know the volume of space to be filled. The seam width is recommended from 1.5 to 3 mm. To the joint depth, approximately equal to the thickness of the tile, you need to apply a coefficient of 1.5, which will take into account material shrinkage, humidity, etc.

To calculate the volume of grout, divide half the perimeter of 1 tile by its area and multiply by the thickness. Multiply the result by the width of the seam and by 1.5 (coefficient). The result will be the mass (in kg) of grout required for 1 sq.m of coverage. For example, with a joint width of 2-3 mm and a tile area of ​​0.04 sq.m, one kilogram of grout is enough for 3.5 sq.m.

Let's sum it up

As a conclusion, we can say that determining the area for laying tiles is not always effective and accurate, especially for small rooms. Using the calculation formula in small rooms is also too complicated and impractical. It is better to make piece by piece calculations.

In the above examples, for simplicity of calculation and understanding of its very principle, the dimensions were taken as the initial data standard apartment and single-color ceramics without decoration or borders. These examples are quite enough to use the described rules to calculate the required amount of tiles for different colors, when installing curbs, etc.

    The commentators are amazing. You really had no idea how to count the number of pieces without this article? Unfortunately, the article did not touch on the topic: what size tile to choose, which wall to use as a base, so that you don’t have to cut pieces.

    Whoever wrote the article must be a genius. I could not even imagine that everything is so simple! I just got around to renovating my bathroom and thought I couldn’t handle it at all. Well, not my profile at all. It turned out that everything was just like that! Now I can check with people at hardware stores to see if they are trying to sell me a lot more tiles than I really need. This information really turned out to be very useful and timely.

    For the most accurate calculation, so that there is no extra costs on the material, first decide on the choice of tiles. Knowing its size, it will be mathematically simple to calculate the exact number of tiles for a certain surface, which will save your waste. Also, do not forget to take into account and discard when calculating the tile joint. Since the tiles do not fit joint to joint, and when laid under the “crosses” there remains a gap of 2 to 5 mm.

    The calculations for the bathroom in the comments are not entirely correct. Because modern tiles carried out in the following sizes - for the floor 30x30, for walls 20x3 0, etc. Therefore it should be calculated like this:
    Floor length 2.50m. - these are 8 rows of 30 cm = 2.40 + 10 cm. pruning
    width 1m is 3 rows + 10cm. trimming, total: 8 x 3 = 24 pcs + trimming 8+4 = 12 divided by 2 (the middle will most likely have to be thrown out) = 6 pcs.
    30 pcs per floor + 4 pcs stock.
    Walls - width 2.5+2.5+1+1-0.75 (doors)=625 mm. – 32 rows of 20cm tiles.
    height 2.5 x 30 cm. = 8.5 rows
    32 x 8.5 = 272 pcs.
