How to calculate the number of wallpapers: per room as needed, calculate by area, how to calculate rolls at 18 meters

To paste the wallpaper on the wall at no extra cost, you need to use a construction tool to measure the area of ​​your walls To paste wallpapers on walls without extra costs, you need to use a construction tool to measure the area of ​​your walls This will help roulette, but the type of wallpaper must be taken into account. Wallpaper with a picture, paper, vinyl, fabric wallpaper, they all have a feature of length and width, and also sticking on the walls, so the calculation must be carried out taking into account all factors, not just the dimensions of the room. There are several options for calculating the required number of wallpapers per room.

To accurately calculate the number of wallpaper needed for a room, you need to use a construction tape measure, measuring the perimeter of all walls without doorways,above and below the windows.

How to calculate wallpapers per room on the walls

The number of wallpaper can be calculated correctly, knowing the perimeter of the room being pasted. The perimeter is the sum of all sides, which means that the perimeter of the room is the sum of all sides along the length. How to get this number?In order to measure the perimeter, you will need a building measuring tape. The length of all rooms must be measured with a tape measure, 4 walls are obtained, 2 walls are of the same length, the remaining 2 walls will have a different length. Consider this for an example of a wall whose perimeter is 4x2.Two walls have a length of 4 m and 2 walls have a length of 2 meters. The formula is as follows: 4x2 + 2x2 = 12 meters perimeter of the room.

This is not all, it is further necessary: ​​

  • Find out the height of the walls;
  • Calculate how many stripes of wallpaper comes from a single roll of wallpaper;
  • Calculate the number of necessary wallpaper stripes for the room;
  • Calculate the number of necessary rolls of wallpaper. Knowing the perimeter of the room you can calculate the required number of wallpapers

    The height of the walls of the room is measured as well as its width, using a tape measure, the tape measure weighs a little, it is very convenient to measure. The standard height of walls in living quarters and apartments is 2.5-3 meters. To find out how many stripes of wallpaper will come from a single roll of wallpaper, you need to split the height of the walls by the length of the wallpaper in the roll, but you need to know how many meters of wallpaper in one roll. If the roll of wallpaper 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 bands 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 for the given room from the selected roll are needed. To do this, you need to measure the width of a roll of wallpaper and divide it into the perimeter of the room.

    With standard wallpaper with a width of 53 cm and 12 meters of the perimeter of the room being glued, as in the example, the following formula is obtained: 12: 0.53 = 23, rounding, which means that the wallpaper needs 23 stripes of wallpaper.

    And the last step is to calculate the number of wallpaper needed for the room. The necessary number of strips for the room should be divided into the number of strips in a roll by the formula: 23: 4 = 6, rounded. It turns out that for a room measuring 4x2 meters you need 6 rolls of wallpaper with a stock.

    The approximate calculations are given, as each room and room in it can have different heights, widths, swings, so it is worthwhile to accurately and carefully make calculations, taking into account possible unevenness of walls and ceiling.

    How to make a wallpaper calculation for a room area

    There is another sure way to calculate the number of wallpaper needed for a room, this is the calculation of the area of ​​the room.

    For this calculation it is necessary to measure the entire area of ​​the room and its wall along the entire perimeter as follows:

    • Measure the length, width and height of the wall surface;
    • Add the length and width of the walls and multiply by 2, becauseIn the building there are 2 identical walls and multiply by the height of the wall;
    • The width of the roll is multiplied by the length.

    After the measurements of the area of ​​the room, you can take the required number of wallpaper for gluing. On the example of a room with an area of ​​4x2 m, it is possible to compose a formula for calculating wallpaper, 2x( 4 + 2) x 2.5 = 30 m2, the area to be glued is obtained. Next, you need to calculate how much the area will be covered with one roll. Using the example of a standard roll, we get the formula: 0.53 m( standard roll width): 10 m( standard roll length) = 5.3 m2.One roll of standard wallpaper for the width and length, you can glue 5.3 m2 of the wall. The last step is to properly calculate the necessary number of rolls of wallpaper for a room of 4x2 meters, you need to divide the surface area by the area of ​​the wallpaper roll, for example, 30: 5 = 6.For wallpapering the room area of ​​4x2 m and a height of 2.5 m, you need 6 rolls of wallpaper. As in the result of the first measurement, and according to the results of the measurement of the area of ​​the room, 6 rolls of wallpaper leave.

    It is better to always take the wallpaper with a small margin, even if you have accurately calculated the area of ​​the room It's better to always take a good stock with a small margin, even if you accurately calculated the area of ​​the room

    Calculations using the formula are very accurate, the excess wallpaper, like the lack of them, will not work, but when calculating, Which is glued wallpaper.

    It's better to take a wallpaper with a small margin to be able to restore the wall in case of damage to wallpaper, than then look for similar wallpapers that you can not find, an extra cut is always useful.

    Drawing wallpaper by drawing

    The most difficult calculation of the necessary wallpaper for a room is the calculation of wallpaper with a picture, it is difficult because the drawing needs to be selected, during which a lot of waste is formed. If there is a slant on the walls, uneven angles or there is a difference in the height of the walls, there may be differences in the figure. Correctly gluing wallpaper with a picture, just picking up an ornament, will provide a good view of the room, without defects.

    An important factor is the way to glue the wallpaper. The wallpaper with a picture is only glued to the joint in order to achieve a harmonious combination of the pattern.

    In order to properly select the required number of wallpaper with a picture for the room, first of all, it is worthwhile to orient to rapport, the permissible distance between the elements of the picture. This indicator for each type of wallpaper and picture on them is individual. On wallpaper with floral ornaments, the rapport is smaller, and on the wallpaper with geometric figures and lines, rapport is always greater. The expense of wallpaper with geometric lines will be more than with a floral ornament.

    If you glue wallpaper with a picture, then you need to take 2 or 3 rolls more If you glue wallpaper with a picture, then you need to take 2 or 3 rolls more Each roll of wallpaper that requires selection during the gluing process specifies the exact version of the rapport:

    • Geometry - above 50 mm;
    • Flower print - up to 50 mm;
    • Abstraction - 10-50 mm of the rapport.

    The required number of wallpaper with a pattern along the width of the pasted surface and its area is calculated, as in the selection of conventional wallpapers. The only feature is the rapport indicator on the roll. A large indicator of the rapport leads to the fact that you have to buy 2 or more rolls more than the usual wallpaper without a picture, and there will be many leftovers.

    Before choosing for your home wallpaper with a picture, you need to calculate the area being pasted, the number of wallpaper needed and the price, will it be profitable for the price?Waste from wallpaper with a picture is very difficult to pick up to the places of slopes, openings and they almost never go anywhere.

    Finished calculations of the number of wallpapers

    In order not to waste time on measuring and calculating the area for wallpapering, accurately and quickly help to calculate the necessary number of wall-papers on the walls of a ready-made table of calculations that can be viewed and obtained ready-made figures.

    Using a spreadsheet, you can calculate the exact number of wallpaper that will be needed to decorate the room Using the calculation table, you can calculate the exact number of wallpapers that will be needed for finishing the room Based on the finished table, you can get information about:

    • Height of the walls and ceilings of the room;
    • Room perimeter;
    • Roll length;
    • Number of rolls and stripes of wallpaper.

    The table data is approximate and cutting the strip of wallpaper before gluing, you need to leave a little extra length to hide possible gaps on the walls.

    Using calculated parameters of the walls of the room and taking into account the width of the wallpaper rolls, it is possible to calculate quickly and accurately.
