Wallpaper is the most popular means for wall decoration in residential premises. With their help, you can make absolutely any design in the room without resorting to excessive financial costs. When choosing wallpaper, consumers face a problem right choice number of rolls. How to calculate the number of wallpapers correctly?
Usually, the roll label indicates an approximate scheme for calculating the number of wallpapers. To find out the value yourself, you must calculate the following parameters in advance:
The length and width of the wallpaper roll can be seen on the label upon purchase. Knowing the values will help to correctly calculate the number of wallpapers per room.
Some 20 years ago, all wallpapers on the territory of countries former USSR had standard parameters length and width: 50 cm by 10 m. modern world market for repair materials a large number of various types of wallpapers. Let's consider the main ones:
Main stages of work:
How to count the number of wallpapers for one room? Before you get started, you need to prepare the following tools:
It is necessary to draw a plan of all the rooms in the room. To do this, you need a ruler and a pencil. Absolute precision and scale ratio are not required here. The main thing is to schematically depict the room necessary for the calculation.
After the walls are schematically depicted, the location of the windows and doors in the room should be indicated on the plan. Scale and precision values can also be ignored.
How to calculate the number of wallpapers? To do this, you should find out the values of the sides of 1 roll and the values \u200b\u200bof the surface area of \u200b\u200bthe walls of the room. To calculate the last number yourself, you must do the following:
For the calculation, you will need to know the value of the perimeter of the room. To find it, you need to get the sum of the lengths of all the walls of the room.
The resulting perimeter must be divided by the value of the width of one roll. It is indicated on the wallpaper label. The resulting value will show how many wallpaper sheets will be required to paste over the entire room, excluding window and doorways.
Next, you should calculate how many canvases one wallpaper roll will last. To do this, the value of the length of the roll should be divided by the value of the height of the room. The resulting number will show how many whole strips will come out of one roll.
How to calculate the number of wallpaper rolls for pasting the entire room? To do this, the previously obtained value of the total number of wallpaper canvases should be divided by assigned amount strips from one roll. The resulting value is rounded up to an integer. We have determined the total number of rolls required for one room.
Wallpaper should be purchased after all measurements have been completed. Compliance with these rules will allow you to find out how to correctly calculate the number of wallpapers for a room.
Specify required dimensions in meters.
Room dimensions:
Y– The length of the first side of the room to be wallpapered.
X- The length of the second side of the room for gluing.
H- Room height.
P– Perimeter (the sum of the lengths of all sides). To calculate the value of the perimeter of a room, add the length of all its walls.
D– Distance from the beginning of gluing to the first corner. Meaning D measured from the beginning of gluing to the first corner (clockwise), it cannot be equal to or greater than the length of the wall.
To carry out the calculation, you can set either the length of the walls of the room or its perimeter (in the second case, the option to start gluing will not be available).
If the room has a rectangular or square shape, enter the parameters Y, X,H. For premises irregular shape with ledges and recesses, it is possible to calculate by specifying the values H And P.
Window:
If the room has a window opening, press "Add window" and enter its dimensions: length WX and height WY.
WZ- The distance from the beginning of wallpapering determines the location of the window in the room. Enter the distance from the starting point of pasting to the window.
The number of added windows is not limited.
Doors:
In order for the program to take into account the presence of a doorway in the calculation, you must click "Add doors" and enter their lengths DX and height DY.
DZ– Distance from the beginning of wallpapering to the doors.
It is possible to add multiple doors.
Wallpaper:
L– The length of a roll of wallpaper depends on the type and manufacturer. Standard value L 10.05 m. However, non-woven wallpaper for painting can be produced in rolls of 30 and 50 meters.
W– The width of the roll is determined by the characteristics of the production line and can be 0.53 m (standard), 0.7 m and 1.06 m.
R- Repeating a drawing, or the so-called. rapport is the distance over which the same pattern repeats.
Z- Margin for leveling, the amount of allowance at the floor and ceiling, which, after gluing, must be cut off with a sharp knife to fit the ruler or rule (0.05-0.15 m).
F- Move picture. Check this box if you want to calculate based on the wallpaper repeat offset for matching.
If you want to print the visualization, check the box " Black and white drawing”, so you get a drawing that is close to the requirements of GOST and save color ink or toner when printing.
Important! If incorrect parameters are entered, to continue the calculation, you will be prompted to pay attention to the corresponding parameter and make changes.
The calculator will help you calculate total area walls of the room (in m²), calculate the consumption of wallpaper, taking into account windows and doors. You will know the area of one roll of wallpaper, the length of the sheets required for pasting a room of a specified height, taking into account trimming allowances, as well as the number of whole sheets of wallpaper contained in the roll. What will be the remainder of each roll and how many rolls (pieces) of a given length are needed to paste over the room. The calculator will calculate how much wallpaper is needed for the room and how many rolls are needed, taking into account the presence of window and door openings. The total balance of all wallpapers will also be calculated.
Such data allows you to buy right amount wallpaper for the room, taking into account the nuances and glue the room with your own hands or hire professionals. It is advisable to have a stock of one roll in excess of the calculated quantity, this will save time and money in the future, in case of improper cutting or damage.
Have you finally decided to re-paste the wallpaper in your room? It's time for old wallpaper to retire and you are wondering how to calculate the number, how many rolls do you need? Answer next...
The most common wallpaper size is a 10 meter roll half a meter wide 10 m x 0.53 m. It is enough to cover about 5 square meters of wall and or ceiling. There are wallpaper rolls with a length of 15*0.53 m, 10*1.06 and 25*1.06 m.
Special cases
If there are ledges or recesses in the niches of the doors, then add 1-2 additional rolls of wallpaper.
If you are using wallpaper with patterns, you need to add a margin to the height calculation to fit the pattern: 2.50 + 0.05 (cut off excess) + 0.30 (fit the pattern) \u003d 2.95 m.
Ceiling calculation
The ceiling is the same. However Lately wallpapering the ceiling does not look elegant. Today, a lot of embossed ceiling tiles have appeared that look more organic and aesthetically pleasing.
Don't forget to buy one or two extra rolls of wallpaper. Especially if the connections go in a checkerboard pattern, just for your mistakes, the offset is higher and lower.
- Be sure to pay attention to the wallpaper series number. If the series are different, then the difference in color and brightness will be noticeable after pasting.
How to save?
If you made a mistake in the calculation, and it is no longer possible to purchase such wallpapers, then you can purchase similar ones. And decorate some of the walls with other wallpaper. In fact, this option looks very modern and non-standard. In this case, the view zones will change, that is, from different parts rooms, her appearance will be different, which will also have a pleasant effect on her perception.
Option with no pasting behind the sofa and wardrobe for an amateur.

If you are not sure about the calculations, you can also use the ready-made table to determine the number of wallpaper rolls:
Use the following table to calculate the wallpaper:
Room perimeter (in m) |
|||||||||||
Roll size 0.53 / 10.05 m = 5.33 m2
Room perimeter (in m) |
||||||||||||
Roll size 0.53 / 15m = 7.95m2
Room perimeter (in m) |

Roll size 1.06 / 25m = 26.50m2
A tape measure will help with this, but the type of wallpaper must be taken into account. Wallpaper with a pattern, paper, vinyl, fabric wallpaper, they all have a feature of length and width, as well as gluing to the walls, so the calculation must be carried out taking into account all factors, and not just the size of the room. There are several options for calculating the required number of wallpapers per room.
The number of wallpapers can be correctly calculated, knowing the perimeter of the room to be pasted over. The perimeter is the sum of all the sides, which means the perimeter of the room is the sum of all the sides along the length. How to get this number? In order to measure the perimeter, you will need a construction tape measure. The length of all rooms must be measured with a tape measure, it turns out 4 walls, 2 walls will be the same length, the remaining 2 walls will have a different length. Consider this on the example of a wall whose perimeter is 4x2. Two walls are 4 meters long and 2 walls are 2 meters long. The formula is as follows: 4x2 + 2x2 \u003d 12 meters the perimeter of the room.
The height of the walls of the room is measured in the same way as its width, using a tape measure, the tape measure weighs a little, it is very convenient to measure. standard height walls in residential premises and apartments is 2.5-3 meters. To find out how many strips of wallpaper will come out of one roll of wallpaper, you need to divide the height of the walls by the length of the wallpaper in the roll, but for this you need to know how many meters of wallpaper are in one roll. If the wallpaper roll is standard, it has a length of 10 meters, if the height of our walls is 2.5 m, then the calculation formula will be: 10:2.5=4. It turned out that 4 stripes will come out of one roll of wallpaper. After the number of wallpaper strips from one roll has been calculated, you can calculate how many wallpaper strips will be required for a given room from the selected roll. To do this, you need to measure the width of the wallpaper roll and divide it by the perimeter of the room.
With standard wallpaper with a width of 53 cm and with 12 meters of the perimeter of the room to be glued, as in the example, the following formula is obtained: 12: 0.53 \u003d 23, rounded up, which means that 23 strips of wallpaper will be needed to glue the room.
And the last step is to calculate the amount of wallpaper needed per room. The required number of strips for the room must be divided by the number of strips in the roll according to the formula: 23:4 = 6, rounded up. It turns out that for a room of 4x2 meters you will need 6 rolls of wallpaper with a margin.
Approximate calculations are given, since each room and room in it can have different heights, widths, differences, so it is worth making accurate and careful calculations, taking into account possible uneven walls and ceilings.
For this calculation it is necessary to measure the entire area of \u200b\u200bthe room and its wall around the entire perimeter as follows:
After measuring the area of the room, you can consider the required number of wallpapers for gluing. Using the example of a room with an area of 4x2 m, you can draw up a formula for calculating wallpaper, 2x (4 + 2) x 2.5 \u003d 30 m 2, you get a pasted area. Next, you need to calculate how much area one roll will seal. Using the example of a standard roll, we obtain the formula: 0.53 m (standard roll width): 10 m (standard roll length) \u003d 5.3 m 2. One roll standard wallpaper in width and length, 5.3 m 2 walls can be glued. The last step to correctly calculate the required number of wallpaper rolls per 4x2 meter room is to divide the surface area by the area of the wallpaper roll, for example, 30:5=6. For wallpapering a room with an area of 4x2 m and a height of 2.5 m, you will need 6 rolls of wallpaper. Both as a result of the first measurement, and according to the results of measurement by the area of the room, 6 rolls of wallpaper come out.
Calculations according to the formula are very accurate, there will be no extra wallpaper, as well as a lack of them, but when calculating, it is worth considering the features of the room for which the wallpaper is glued.
It is better to take wallpaper with a small margin in order to be able to restore the wall in case of damage to the wallpaper than to look for similar wallpapers later, which you can not find, an extra cut is always useful.
The most difficult calculation of the necessary wallpaper for a room is the calculation of wallpaper with a pattern, it is difficult because the pattern needs to be selected, during which a lot of waste is generated. If there is a slope on the walls, uneven corners, or there is a difference in the height of the walls, there may be differences in the pattern. Proper gluing of wallpaper with a pattern, accurately choosing an ornament, will provide good view rooms without defects.
An important factor is the methods of wallpapering. Wallpaper with a pattern is glued only joint to joint in order to achieve harmonic combination drawing.
In order to correctly select the required number of wallpaper with a pattern for a room, first of all, it is worth focusing on rapport, on the allowable distance between the elements of the pattern. Such an indicator for each type of wallpaper and pattern on them is individual. On wallpaper with floral patterns, the rapport is less, and on wallpaper with geometric shapes and lines, rapport is always greater. The consumption of wallpaper with geometric lines will be more than with floral patterns.
On each roll of wallpaper that requires selection during the gluing process, it is indicated exact variant rapport:
The required number of wallpaper with a pattern is calculated according to the width of the pasted surface and its area, as in the selection ordinary wallpaper. The only feature is the rapport indicator on the roll. A large rapport indicator leads to the fact that you will have to buy 2 or more rolls more than ordinary wallpaper without a pattern, and there will be a lot of leftovers.
Before choosing wallpaper with a pattern for your home, you need to calculate the area to be pasted, the number of wallpapers needed and the price, will it be profitable for the price? It is very difficult to pick up waste from wallpaper with a pattern to the places of slopes, openings, and they almost never fit anywhere.
In order not to waste time on measuring and calculating the area for wallpapering, a ready-made calculation table will help you accurately and quickly calculate the required number of wallpapers on the walls, which you can view and get ready-made indicators.

Focusing on the finished table, you can get data about:
These tables are approximate and when cutting wallpaper strips before gluing, you need to leave a little extra length to hide possible gaps on the walls.
Using ready-made indicators for calculating the walls of a room, as well as taking into account the width of wallpaper rolls, you can quickly and accurately calculate.
Always wallpapering laborious process, even more difficult, to choose the exact right amount of wallpaper per room. Conducted accurate calculations the size of the room with the help of a tape measure, and sometimes an assistant, you can get the right indicators and calculate the right amount of wallpaper. When everything goes well in the repair, the repair will not be a burden, but a pleasure.
Perhaps it is not only the most traditional way, but also the most versatile. Given the wide selection of wallpapers in construction stores, each person will be able to choose wallpaper for their home or office, which is best suited to him both in terms of cost and quality.
Often, when coming to a wallpaper store, customers are already quite savvy about the quality of wallpaper and the price per roll. They know what wallpaper and which manufacturers are better to buy and glue on the walls.
But the question arises about the number of rolls that are needed to wallpaper the walls. In this article, we will try to give an example of how to visually calculate how many rolls of wallpaper you need to glue a room.
If you prefer simple wallpapers that do not have a pattern at all, or have a small pattern that does not require selection when pasting walls, then counting the number of rolls for a particular room is quite simple.
It is necessary to make measurements of the room, determine the length and width of the room. After that, it remains only to multiply the length by the width.
Below is the calculation scheme S area of the room.
Calculation example:
Room length= 3.9 meters (or 3 meters 9 centimeters)
Room width\u003d 3.45 meters (or 3 meters 45 centimeters)
S room area\u003d 3.9x3.45 \u003d 13.45 meters, round up to a whole number.
We get as a result S=14 sq.m(or 14 square meters)
After that, we determine the number of rolls required for the wallpapering room in the tables below.
Calculation example according to the table:
In the example above, we got 14 sq.m, if we chose wallpaper width 53 centimeters, then we look further into table number 1 in the left column room area with number 14 . Depending on the height of the room, select a column in the table in the name ceiling height(if we have a room height of 2.65 meters, then look in the column for the ceiling height Ceiling height 2.6 - 3 meters).
As a result, when the area of the room (floor) is equal to 14 sq.m., for roll width 53 centimeters, Ceiling height 2.6 - 3 meters, V table number 1 we get - we need 10 rolls.
Accordingly, with the area of \u200b\u200bthe room (floor) equal to 14 sq.m., for roll width 70 centimeters, Ceiling height 2.6 - 3 meters, V table number 2 we get - 7 rolls of wallpaper
And with the area of \u200b\u200bthe room (floor) equal to 14 sq.m., For meter wallpaper wallpaper width 106 centimeters, Ceiling height 2.6 - 3 meters, V table number 3 we get - 5 rolls of wallpaper.
That's all the arithmetic.
Below are 3 tables depending on the width of the wallpaper (for 53, 70 and 106 centimeters):
Table #1 53 .

Note: In tables The areas of the premises are indicated by floor(and not the area of the walls), the calculations are made on the average standard room, which usually has one door and one window.
It should also be taken into account that when calculating the number of wallpaper rolls according to the tables, sometimes it is necessary to use and take into account the selection of the pattern that exists on the wallpaper itself. If the wallpaper needs to be adjusted, then for every 6 rolls of wallpaper you need to add one more roll.
If you don’t want to manually calculate how much wallpaper you need per room, if you didn’t understand something when describing the calculations, or you can’t for some reason calculate how much wallpaper you need, then you will be helped online calculator.
Calculator for calculating the number of wallpapers per room - calculate online
We will not load you with tedious mathematical calculations. You only need to measure the basic parameters, and the wallpaper calculator will approximately calculate the required number of wallpapers for your room.
Fractional numbers must be entered with a dot, not with a comma! Those. 5.2 - wrong, 5.2 - correct
! The calculation is approximate. The result values may differ slightly from the true value, as all rooms are different and have various characteristics: square, rectangular, with ledges. Plus, windows and doors in the room, as well as their location, will have some influence on the error. If you decide to glue the wallpaper with a pattern fit (rapport), then for every 6 rolls you need to add one more roll to the result.
An example of calculating wallpaper for a room on our calculator: room width - 3.21 meters, the length of the room - 3.75 meters and room height (ceiling height) 3 meters. We decided to buy wallpaper long 10 meters, wide 1.06 meters.
Thus, we substitute our numbers into the value fields and get the result - 4 roll. If our wallpaper requires adjustment of the pattern, then you can safely add another roll, in total there will be 5 rolls of the meters we like.
