To calculate, you will need a measuring tape, a notepad and a calculator.
Room measurements
First you need to measure the width, length, and height of the room in which you will be glued.
In addition, the dimensions of door and window openings should be determined. The parameters of windows and doors will help you make the calculation more accurate and not take into account the area that does not need to be pasted over.
How to calculate wallpaper in a room around the perimeter
The first step is to calculate the perimeter of the room, which is:
Perimeter \u003d (one wall length + adjacent wall length) * 2
Calculating the estimated height of the web
To find out how long your wallpaper will be, use the formula:
Estimated strip height \u003d room height + ornament pitch (rapport) + stock for upper and lower allowances (5 cm)
Calculation of the number of stripes for pasting a room
To do this, you first need to measure the width of the strip of wallpaper that was selected for gluing.
Then we calculate the number of strips required to cover the entire room:
Number of stripes per room \u003d perimeter / width of wallpaper stripe
Important! The resulting numbers should be rounded up to a whole value, otherwise you can get a few centimeters of the wall without wallpaper.
Calculation of the number of strips from one roll
After we have determined the number of strips of wallpaper per room, we can calculate the number of stripes per roll. To do this, you will need to know the length of the roll (usually it is indicated on the label).
Number of strips from 1 roll \u003d roll length / estimated strip height
Important! The resulting numbers should be rounded down to the nearest whole so that only whole canvases are glued to the wall.
Calculation of the number of rolls per room
After all the calculations done, we can finally find out the number of rolls for pasting the entire room:
Number of rolls \u003d number of strips per room / number of strips from 1 roll
Important! All received numbers are rounded up, because rolls must be ordered whole.
How to calculate wallpaper for a square room
The calculation of wallpaper around the perimeter of the room is not always suitable, since the presence of windows and doors is not taken into account, so you have to count by area.
Calculating the area of \u200b\u200bwalls
To calculate the area, use the following formula:
Total area \u003d wall length * wall height
Now let's calculate the area of \u200b\u200bthe walls that will be covered with wallpaper. To do this, you first need to calculate the area of \u200b\u200bwindow and door openings, and then use the formula:
Wallpapering area \u003d total area - area of \u200b\u200bwindows and doors
Calculation of the number of rolls
A standard roll 53 cm wide and 10 m long is usually enough for 5 square meters. rooms.
To calculate the number of rolls for the whole room you need:
Number of rolls \u003d area of \u200b\u200bthe room / area that can be glued with 1 roll
Important! Round up the resulting number.
If your wallpaper with a pattern
If there is a large drawing on the wallpaper, find out its report, and then calculate the ceiling height multiple of it and carry out calculations with it.
For example, the wall has a height of 2.6 m, and you decided to buy wallpaper with a pattern step of 40 cm.It turns out that you need to cut into pieces 2.8 (0.4 * 7), because if you cut at 2.6, the pattern will not match.
So recalculate everything that you measured, just as if your walls are 2.8 m high, and not 2.6.
Hints
If you are still not sure of the correctness of your calculations, then below are the tables-tips.
How do I use tables?
First you need to calculate the perimeter or area of \u200b\u200bthe room, depending on which table you will use.
Tables by area:
To use the table below, you need to determine the length of the roll, and also make sure that the width of the wallpaper strip is 50 cm. Then you can easily determine the number of rolls you need.
For the following table, in addition to the area of \u200b\u200bthe room, you only need to measure the height of the ceilings. After that you can find out the required number of rolls per room.
Perimeter tables:
In order to use the tables below, you will need to decide on the width of the strip of the selected wallpaper, as well as the length of the roll. After that, you measure the height of the ceiling and see from the table how many rolls of wallpaper will be needed.
Roll size (strip width / roll length \u003d glued area): 0.53 m / 10.05 m \u003d 5.33 sq. M

Traditionally, renovating a room is not complete without changing the wallpaper. But on the market of modern finishing materials, there are many wallpapers of different types, colors, sizes and other characteristics. How to optimally calculate the required amount of this material?
So, it was decided to change the wallpaper, but what is the best way to calculate the necessary materials so that you do not overpay for the excess, and then not buy the missing amount (especially since batches of the same wallpaper may differ in color, pattern, texture)? Is there a general calculation principle for any type of wallpaper or should it be calculated differently depending on which wallpaper will be used?
First you need to decide:
- which room will require wallpaper calculation (living room, hallway, kitchen)
- what type of wallpaper you plan to use (paper, non-woven, bamboo, liquid, etc.)
- what are the dimensions of the wallpaper (length, width), pattern, texture
- will the ceiling be covered with wallpaper in addition to the walls?
Depending on the room in which the wallpaper is planned to be glued, their type is selected. For example, velor wallpaper can be used in the hall, but in the kitchen they will be impractical and inappropriate; washable coverings are more suitable in the corridor. Not only the dimensional, but also the quality characteristics of the wallpaper can affect the calculations.
The calculation of the number of wallpapers is influenced by the following:
- dimensions (length, width) of wallpaper
- design, pattern, texture, type of wallpaper
- glued surface area
- flatness of the surface
- the presence of doors, windows, ledges, arches, etc. in the room
- design solution in the design of the room (sometimes different colors and types of wallpaper are used).
Of course, the rooms are different, the roll wallpapers are also of different lengths. There is a general formula that works for any type of wallpaper:
R: B: 3 (or 4 - depending on whether you need to fit the picture or not).
Where P is the perimeter of the room, B is the width of the roll.
The figure obtained by this formula is rounded up to a higher number. Of course, for those who like more accurate calculations, more accurate measurements will be needed, and taking into account other parameters.
How to calculate the required number of rolls.
To calculate correctly, it is not necessary to specially invite builders, all calculations can be done independently. The main thing is to measure everything accurately. Therefore, it is worthwhile to arm yourself with a construction tape and measure the perimeter of the room in which the renovation is planned (this is the length of all walls minus the size of windows and doors).
It happens that in the room not the entire surface is planned to be pasted over with wallpaper (for example, the calculation is carried out for the kitchen, and the wallpaper will be glued together with the tiles), then you need to subtract the area that the tile apron will occupy from the area of \u200b\u200bthe entire room.
It is important to consider: if wallpaper with a pattern is selected, then their consumption increases by 1.5 times, since the pattern will need to be adjusted.
For the correct calculation of the wallpaper, it is important to know the exact dimensions of the room, the number and area of \u200b\u200bwindow and door openings.
2AH + 2BH \u003d S
S is the required total area of \u200b\u200bthe walls of the room,
H is the height of the room,
A is the length of the room,
B is the width of the room.
If the length of the walls is not the same, and their number is not 4, but, for example, 5, then you do not need to multiply by two, and the formula can be like this:
S \u003d AH + BH + CH + DH... And here: A - the length of the first wall, B - the second, C - the third, D - the fourth.
This formula is suitable if the height of the walls is the same, but their lengths are different. If the height is different (for example, there may be a podium, steps), then it is necessary to indicate it differently.
It is important to consider:
For the calculations to be accurate, you need to measure not by eye, with steps, elbows (especially since steps and elbows may be different for people), but with a ruler, tape measure.
It is better to record the measurement results in centimeters and not round off as accurately as possible.
Calculation methods
Method 1 (using old wallpaper).
If there are old wallpapers in the room and they coincide in width with the new ones, and you do not need to combine the pattern rapport, then you can simply measure the height of the wall, find out how long the roll is in the new wallpaper (now rolls of 18, 12, 10, 7 meters are produced) and count the number of stripes of old wallpaper on the walls. Dividing the length of the roll by the height of the wall, we find out how many panels will turn out in one roll. Well, here it is already easy to calculate the required number of rolls.
- Let's say the height of the walls is 2.5 m, the roll is 10 m, the strips of old wallpaper are 20 pcs.
- 10: 2.5 \u003d 4 (the number of panels in one roll).
- If there are 20 segments in total, then dividing by 4, we get 5 rolls necessary for pasting the entire room.
If the number turned out to be fractional, then it is usually rounded up.
Method 2 (calculation "from scratch").
If there is no wallpaper in the room, the walls are cleaned, then in the calculations you can proceed as follows:
- Find the area of \u200b\u200beach wall. Pre-measure its length, width and multiply.
- If there are window or door openings in the wall, we calculate and subtract their area from the total area of \u200b\u200bthe wall.
- If any decor is planned, and it will take up space where wallpaper will not be needed, we also subtract the area of \u200b\u200bthis surface from the total area of \u200b\u200bthe wall.
- Let's summarize the results obtained for all walls.
- Knowing the length and width of the wallpaper in a roll, we can calculate the area of \u200b\u200bthe wallpaper.
- Dividing the area of \u200b\u200bthe room by the area of \u200b\u200bthe roll, we find out the required number of rolls.
The same wallpaper, if released at different times, may differ in shades.
Calculation for wallpaper with a pattern
If the drawing is pale or not very noticeable, you can act according to the general scheme, but it is bright and noticeable, you will have to take into account the step of the ornament. Usually the step of the ornament is 52-53 cm.
Settlement plan: 
- We measure the height of the wall.
- Divide by the step of the ornament.
- Round the value up and get the rapport number.
- We multiply the resulting rapport number by its value and we end up with the length of the panel cut from the roll.
- To find out the amount of waste, you need to subtract the height of the wall from the resulting length of the panel.
- Further, dividing the length of the roll by the length of one panel, we obtain a coefficient that will help determine the number of required rolls.
- The resulting coefficient is multiplied by the difference, which turned out in step 5.
- The number obtained in clause 7 is subtracted from the total length of the roll.
- If the total area of \u200b\u200bthe room that you plan to paste over is divided by the number from item 8, you will get the required number of rolls.
Let's say:
- length of a roll of wallpaper to be glued, 10m,
- the step of the ornament - 0.53 m,
- wall height 2.8 m,
- total room area - 43 sq.m.
The calculations will be as follows:
- 2.8 m.
- 2,8: 0,53 = 5,28
- Round up to 6.
- 6X 0.53 \u003d 3.18.
- 3.18 - 2.8 \u003d 0.38 m (or 38 cm).
- 10: 3.18 \u003d 3.14 (coefficient).
- 3.14 x 0.38 \u003d 1.19
- 10 - 1.19 \u003d 8.81m.
- 43: 8.81 \u003d 4.8 (i.e. optimally 5 rolls are required per room in this example).
Rolls come in different sizes, but these calculation methods are suitable for any wallpaper: you just need to substitute the numbers that reflect the size of the selected wallpaper.
Calculation of the required amount of liquid wallpaper.
If liquid wallpaper is chosen to decorate the room, then the specifics of the calculations change slightly, but the total area of \u200b\u200bthe working surface will still have to be calculated.
To determine the amount of liquid wallpaper, you need to divide the wall area (how to find it, explained above) by the wallpaper consumption of one package. Usually, this consumption is indicated on each package of liquid wallpaper, but on average it is 3-5 square meters. surface.
For example, if the area of \u200b\u200bthe work surface in the room is 30 sq. m., then with an average consumption of liquid wallpaper in one package of 3 square meters, 10 packages of such wallpaper will be required.
Depending on experience with liquid wallpaper and on the condition of the walls, it is recommended to take 1-3 packages in stock.
If you do not need to dock and fit the pattern, then the calculation will be simple:
How do I know the perimeter of a room?
The perimeter is the sum of the lengths of all sides. We measure all the walls of the room and add up their length.
Example:
We calculate the perimeter of the living room measuring 5x6 m.Let us add the length of all its walls - and we get 22 m.
How many panels do you need to cover the room?
To find out how many strips of wallpaper you need for a particular room, divide the perimeter by the width of the rolls.
Example:
The perimeter of our room is 22 m, and the width of the wallpaper is 1.06 m.Divide 22 by 1.06 - and we get 20.75. We round the result up - and we get 21 panels.
How many sheets will one roll last?
To calculate the number of full panels in one roll, divide its length by the height of the ceiling.
Example:
The length of the wallpaper roll is usually 10 m. The height of our room is 2.75 m. Craftsmen recommend adding an additional 10 cm margin to the ceiling height for easy gluing. Thus, the value of the height of our ceiling will be 2.85 m. If we divide the length (10 m) by this number (2.85 m), then we get 3 full stripes from one roll.
How many rolls of wallpaper do you need?
To find out, you need to divide the number of all panels in the room by the total number of panels that are obtained from one roll.
Example:
In our case, the calculation will be as follows: 21 (the number of panels) is divided by 3 (panels from one roll) and we get 7 rolls of wallpaper 1.06 m wide and 10 m long.
If you are gluing wallpaper with a large pattern
You will need to make sure the stripes are neat to match the pattern. This is true for designs with large geometric patterns, plant images, and other large shapes. Here you need to take into account the rapport - the distance through which the same pattern is repeated. You need to count how many rapports fall on one length of the panel. The larger the rapport, the more rolls you will need to cover spacious rooms. The size of the rapport is indicated on the label. You will find one of the following icons on the label:
Drawing docking
Description
Free docking
Means that wallpaper strips are glued in a standard way, without observing the rules for pattern matching. Such designs do not have a pronounced pattern and can be glued without fitting.
Direct docking
(the indicating report for the PALETTE wallpaper is 64 cm)
With a direct docking, wallpaper strips are glued symmetrically next to one another. Such wallpapers are glued without a special shift to match the pattern.
Offset docking
(indicating the report and offset for example 64/32)
Means that wallpaper strips must be glued with an offset. The first number indicates the size of the rapport, the second is the number (in cm) by which the rapport should be shifted.
Example:
64/32 means that the pattern is repeated every 64 cm, and the next stripe is shifted vertically relative to the previous one by half of the report (32 cm).
Wallpaper is a comfortable modern finishing material. It is especially in demand in the renovation of apartments, where the quality of the walls is poor. Such finishing is usually done on rough plaster, which saves the family budget. Gluing them is a simple task that even a beginner can handle. But how to correctly calculate the number of wallpapers per room?
There are many calculators on the Internet that help you calculate the required number of wallpapers. Nevertheless, it is not worth taking these calculations as a basis: the value inaccuracies might be big enough. This is because three parameters are being set - width height length rooms. At the same time, ledges and niches are rarely taken into account.
Therefore, it is best to count yourself with a calculator, armed with a room plan. On the plan, it should also be noted the grooves in the wall, if they are also pasted over with the same material. When combining several types of material, a plan is drawn up where which section will be located, and the number of wallpapers for each of them is calculated.
Room perimeter
The first step is to find out perimeter rooms - add the length and width, multiply the sum by 2... Example: in a rectangular room with walls 1.5 and 3.5 m, the perimeter is: (1.5 + 3.5) x2 \u003d 10 m.
If there are niches and ledges in the room being repaired, increments are made. Then they think differently, since opposite walls can be of different lengths. In this case, each wall is measured separately, and then the resulting numbers are added. Both protrusions and recesses must be taken into account.
The photo above shows several complex figures - let it be a plan of non-standard rooms. The perimeter of each of them is found as follows:
- AND: 4 + 3 + 4 + 3 + (1 + 1) x4 \u003d 22;
- IN: 6+2+6+8+16+4+4=46;
- FROM: 10+8+14+4+2+8+6+4=56.
How to find out how many canvases you need for gluing
It is not difficult to find out how many canvases you need for gluing. To do this, check the roll width on the label. Standard - 53 or 100 cm... Then the perimeter of the room is divided by this width. If division yields a remainder, then increase this amount by one more.
For example, the perimeter of a room, as in the above example, is 22 m... Divide this number by 53 cm... The result 41.5 is rounded to 42 .
How many pieces can be obtained from a roll
To answer this question, you need to know the height of the walls. In most apartments in apartment buildings, it is 2.3 meters... But to know the exact figure, you need to take measurements in different places. The indicators may differ slightly, and sometimes the drops reach 5 cm... A large value is taken as a basis.
Then the length of the roll is divided by the resulting figure. So, at a height 2.3 m one roll can be divided into 4 parts, but if you do not need to adjust the pattern. If the number came out with a remainder, then rounding down is carried out. For example, ceiling heights 3.2 m... If a 10 m divided by 3.2, it turns out 3 with a remainder of 0.4. This means that three canvases will be obtained from one roll and there will be a length of waste 40 cm.
Attention! Don't throw away small pieces of wallpaper. They are used for small areas - for example, above windows.
Calculation of rolls for one room
To find out how much total material needs to be purchased for one room, the number of canvases is divided by the number of full strips.

Pasting wallpaper on the ceiling
Often, the design of a room involves gluing wallpaper to the ceiling. This tradition is becoming obsolete. This is partly due to the fact that it is not very convenient to paste over a vertical wall. And the possibility of flooding by neighbors from above is not excluded, after which repairs will have to be done. Therefore, suspended structures are becoming more and more popular, which perform not only a decorative function, but also help to hide communications. Often, floors are simply covered with white paint.
But if, nevertheless, there was a need to decorate the ceiling of the room as well, then the material must also be calculated. First, the ceiling area is calculated. For example, in a well-shaped room with walls 4x5 cm the area will be 20 m2... Then they find out the area of \u200b\u200bthe roll by multiplying the width by the length. So, the area of \u200b\u200ba roll length 10 m and width 0.53 m will be 5.3 m2... This means that 4 packages are required for the ceiling. If the ceiling has projections, then this area must also be taken into account. Calculate its dimensions in the same way, and add to the main result.
Prices for various types of false ceilings
Dropped ceilings
Openings of windows and doors
However, professionals do not recommend being greedy. This difference will not yield significant savings. At the same time, some stock of material will not hurt in any case. Home craftsmen, especially those new to repairs, often make mistakes. And perhaps this surplus will help you avoid buying an extra roll.
Furniture
Often, a room is furnished with massive headsets that are difficult to move, and no radical renovation of the interior is expected in the near future. In such cases, it is worth subtracting the area of \u200b\u200bthe wall occupied by an ordinary wardrobe, compartment or shelving from the total perimeter.
But if a part of the wall in the room is occupied by a small cabinet, which you also don’t want to move, then this section should still be included in the total footage. As with windows and doors, this will be a safety margin in case of failure.
Attention! If the furniture hides only part of the wall and does not reach the ceiling, then it is necessary to calculate the length of the segments that need to be glued from above. They must be such that at least 10 cm go behind the back of the cabinet.
Secrets of adjusting the pattern on the wallpaper to save material
Almost always, wallpaper comes with a pattern. If you want to do less fiddling with docking, it's best to opt for a loose fit material. This means that the design on the panels is completely absent or does not need to be adjusted. Examples of this design are stripes, small peas, flowers, dots, etc.
There are concepts such as straight and offset fit, in which the material consumption increases slightly.
A straight fit assumes precise alignment with the pattern of the previous glued strip. To match the ornament, each next strip is moved towards the ceiling until the elements on the seam form a complete picture of the ornament. The height of the repeating part (called the rapport) is indicated on the label.
Another way to fit is offset. This method is used for large images on finishing materials. Such wallpapers are the least convenient, since their use is fraught with high costs. After all, in order for the wall to look neat and aesthetically pleasing, each next canvas is cut out so that it turns out to be half the report longer than the previous one. On the label, the manufacturer reports the highest waste per piece. This information is given as a fractional number - for example, 64/32 ... This means that the rapport value 64 cm, and the displacement length is 32 cm.
Attention! Before purchasing, you must study all the relevant signs on the packaging with the product.
How to calculate the wallpaper if you need to adjust the picture
Wallpaper with a complex pattern must be customized. Therefore, the calculation of such a finish is more difficult. In addition to linear measurements, the rapport height is taken into account. Calculations are carried out in the following sequence:
- Measure the height one strip... This indicator is multiplied by the height of the rapport, and the resulting number is divided by the length of the roll. The number is rounded to the smallest integer.
- Calculate number of rolls according to the method described above.
Attention! Be sure to take into account the rapport when gluing a finishing coating with a complex pattern. If this is not done, then at the end of the work it may turn out that you will have to buy 2-3 rolls.
Another way to save on material is to glue the canvases not to the ceiling itself, but with an indent 20-25 cm... This technique is effective in rooms with high walls, as it visually makes them slightly lower. But for squat rooms, it will not work.

How to save on wallpaper
One way to spend less wallpaper is use a large drawing only on one wall... The rest can be painted or pasted over with plain materials. Another way - canvases with zero offset alternate with bright, large print.
And this is a real find for those who love drawings on the walls, especially large ones. To get the minimum amount of waste, you need cut wallpaper from two or three rolls at once... That is, the first strip is taken from one, the second from the other, then the third roll is alternated or opened. The savings will come from the fact that the pattern in the wallpaper is displaced during production. Therefore, using several streams at once, it is possible to reduce waste.
How to calculate the amount of liquid wallpaper
The material is also called silk plaster. It is based on cellulose, natural polymers. They combine the properties of three types of finishes at once - decorative plaster, roll wallpaper, paintwork materials. Unlike decorative plaster, the mixture does not contain sand and cement.
- cotton;
- silk;
- cellulose;
- silk-cellulose.
Reference! Silk-based products are considered the most durable, cotton products are the cheapest and last the least.
For independent use without the involvement of specialists, silk plaster is produced already tinted. There is also a category of products for professional use. It consists of individual components that must be diluted and painted before starting wall decoration.
The calculation of the amount of liquid wallpaper also depends on the size of the room. Therefore, before starting, it is necessary to take measurements as described above.
Attention! The amount depends on the composition of the finishing material itself. So, the finer the fibers, the less material will be required.
Consumption depends on how correctly the mixture is prepared, and on compliance with the application technology. One package is enough for 3-7 m2 surface. Consumption is indicated on the manufacturer's label.
Step-by-step instructions for preparing liquid wallpaper
Step 1.Water at room temperature is poured into the container - clean, without impurities. The amount of water for 1 package must be specified on the package, for different products the amount is different.
Step 2. Pour gloss into the water (if used, it is usually purchased separately). Then shake the bag with wallpaper and pour the contents into the container.
Step 3. The mixture is thoroughly mixed by hand, passing between the fingers. This will help prevent the adhesive from lumping and dissolving.
Step 4. Withstand the mixture 12 hours, and mix again.
Mixing rules for liquid wallpaper
Each package is mixed with water separately, regardless of how much mixture is required for wall decoration. Immediately prepare as many bags as needed to work with the wall from corner to corner.
You cannot use only half of the package. The fact is that dry components are distributed unevenly throughout the package. Therefore, it may turn out that there is more glue at the bottom, less fibers, or vice versa. When the mixture is diluted, there will not be enough glue, and the wallpaper will not meet the characteristics stated by the manufacturer.

At the same time, if there is a lot of wallpaper, they can be dried and then reused. When mixing some types of silk plaster, it is necessary to use a drill with a mixer attachment.
Technology for applying liquid wallpaper
The mixture is applied with a plastic float or trowel. Take small portions, apply the grater to the wall at an angle 15 °... Depending on the type of wallpaper, the thickness of the applied layer should be up to 2 mm.
The resulting mass is applied using a special pistol. It allows you to save up to 40% finishing material. The design of the device provides for a lot into which the mixture is loaded. The material is sprayed under pressure on the wall surface.
Reference!As you know, ordinary roll wallpaper is afraid of drafts during the drying period. However, when working with silk plaster, on the contrary, it is recommended to ventilate the room for the fastest drying of the finish.
Wallpaper
The easiest way to buy wall murals. Usually they are matched to the size of the wall that they are going to decorate in this way. However, it is important to note that some coatings are used not on one but on two adjacent walls. Therefore, so that part of the picture is not lost, it is necessary to carefully consider in which part of the room it will be used.
Attention! If ordinary wallpapers are also used, then you need to know the size of the former, so that you can save on the latter.
In the form of photowall-paper there are:
- horizontal;
- vertical;
- square.
The canvas is often composed of several elements, the number of which can reach 20 or more.
If it turns out that the canvas is too large, then it is easy to cut it. But with a lack of width or height, empty sections of the wall can be filled with the main finishing material.

How many wallpapers to buy
Even if the amount of wallpaper is calculated correctly, you need to buy at least one more roll in reserve. This is necessary for several reasons.
It is not always possible to stick the strip the first time. The material can be damaged or dirty during operation. In addition, there may be a defect on the canvas, which is not visible upon purchase, since the tapes are rolled up and sealed in film.
Many manufacturers produce limited collections, so after a year you won't be able to buy the same design. But even if the design is preserved, the shade of the dyes may be slightly different, and this will be noticeable on the wall.
As for liquid wallpaper, their consumption may increase due to uneven walls. Therefore, to the total volume, add up to 20% from the base calculation.
From the size of the room (more on that below) and from the design. Usually 10 meters in one roll. If the wallpaper is plain and the ceiling is 2.5 meters high, you can cut the roll into four strips. If the pattern has to be adjusted, there will be three stripes.
stroyday.ruNo pattern alignment: the roll is simply cut into the required number of panels. Usually it is a plain wallpaper, wallpaper with an abstract pattern or vertical stripes.
stroyday.ru The drawing will have to be aligned horizontally so that adjacent stripes start with the same elements. And here everything will depend on the height of the rapport - the distance through which the pattern is repeated (indicated on the label). In the worst case, you will have to throw out almost the full height of the rapport, so when calculating it must be added to the height of the ceiling.
stroyday.ru The drawing is positioned diagonally, so each canvas shifts. As a rule, half the rapport. In this case, the rapport height and the offset value must be added to the ceiling height: you can find both numbers on the label.
How to calculate the number of wallpapers using tables
This is ideal if the room is square or if the wallpaper does not need to be adjusted. All you need is the area of \u200b\u200bthe room and the height of the ceiling.

remont-otdelka-m.ru How to calculate the number of wallpapers mathematically
If the room has a complex shape, there are bends and niches, it is better to count along the perimeter. To do this, add up the lengths of all walls. Window and door openings less than 60 cm wide are equated to a flat wall, wider ones are excluded from. The resulting value is rounded up.
Example: 2.75 m + 3 m + 0.4 m + 2.85 m + 4 m + 0.65 m \u003d 13.65 m ≈ 14 m.
Then you need to determine the number of strips: divide the perimeter by the width of the roll. Let's go back to our example: 14 m / 1.06 m \u003d 13.2. Rounding up - 14 canvases of wide wallpaper. For narrow wallpapers: 14 m / 0.53 m \u003d 26.4. That is 27 bands.
Now you need to determine how many strips can be obtained from one roll: the length of the roll must be divided by the length of the strip. And there can be three options:
- If the wallpaper does not require adjustment, the length of the strip is equal to the height of the ceiling. 10 m / 2.75 \u003d 3.6 ≈ 3.
- If the wallpaper is straight-joined, the strip length is equal to the sum of the ceiling height and the rapport height (0.6 m). 10 m / (2.75 + 0.6) \u003d 2.9 ≈ 2.
- If the wallpaper has a combined docking, the length of the strip is equal to the sum of the ceiling height, the rapport height (0.6 m) and the offset value (0.3 m). 10 m / (2.75 + 0.6 + 0.3) \u003d 2.7 ≈ 2.
The last step: the number of strips we need is divided by the number of strips in the roll. If the wallpaper is wide, 14 should be divided by 3 or 2. If narrow, divided by 3 or 2, 27 stripes will be needed.
How to calculate the number of wallpapers using services and applications
The fastest way, if you know the parameters of the room, and the simplest, if you are not friendly with mathematics. There are many wallpaper calculators on the web, here are just a few good ones.
- Wallpaper calculator from calc.by. It counts both by area and by perimeter, allows you to exclude door and window openings from the calculation. You can also set the roll width and footage.
- Wallpaper calculator from calc.ru. Calculates the perimeter. Helps determine how much wallpaper and glue you need.
- Wallpaper calculator from remont-online.com. First, the configuration of the room is selected, then the width of the walls and wallpaper is driven in. You can also specify the price per roll to find out the total cost of pasting.
If you are already in the store, use the application for calculations. Here are two well-rated freebies. non-food products of proper quality that cannot be returned or exchanged, there are finishing materials. But we are only talking about goods sold by the meter.
In other words, if you don't like the wallpaper, you can take it back to the store. All rolls. In this case, the seller will offer you a similar product, and if there is none, you can write a request for a refund.
It will be problematic to return one or two extra rolls afterwards. But large stores tend to cater to customers. After all, they buy wallpaper in large quantities, and plus or minus one roll does not particularly affect the sale. Customer loyalty is more valuable.
