How many square meters in a roll of wallpaper: we consider the required number

The most popular finishing material decorating the walls of our apartments has been wallpaper for many years, the variety of which continues to grow steadily. Going to purchase the wall covering of your dreams, you should make an accurate calculation of the required amount, which directly depends on how many meters are in the roll and what is the width of the selected wallpaper.

Common wallpaper sizes

A large size range of wall coverings is explained by a variety of materials, textures, types, manufacturers, as well as manufacturing countries. An approximate list of standard values for common species is as follows:

paper wallpapers, as a rule, have a width of 53 centimeters and a length of 10 m (sometimes - 8 and 12 m);
vinyl sheets - 50 cm wide and 15 m long;
non-woven material - width 106 cm, footage - 10 or 12 m;
textile coverings can have a width in the range from 53 to 80 cm and a length of 10 m;
parameters fiberglass - 53 cm wide by 10 m long.

Interesting! Highly demanded meter-long paintable wallpapers are found in rolls of 25 or even 50 m, and super-dense non-woven, used as accent elements, are 5 m each.

Note! The standard for the width of the canvas of British, Italian and some German manufacturers is 74 cm, so it is worth double-checking the markings once again.

Calculation of the required quantity

You can calculate the number of specific wallpapers in two ways:

based on the area of the glued surface;
determining the desired number of lanes.

Method number 1

The calculation based on the area value proceeds as follows:

The height and length of each wall intended for pasting is measured, calculated total surface area.
If necessary, the areas of window and door openings are subtracted from this value. The resulting value in m2 is the required amount of coverage.

If the room has a single small window and a single-leaf door, then their dimensions are usually not taken into account in the calculations, leaving the estimated surplus “in reserve”. In the case of a non-standard layout (panoramic window, several or enlarged doorways), the difference can reach up to a whole roll, which means that it makes sense to calculate the working surface area as accurately as possible.

Now we determine how many square meters are in each roll of wallpaper. To do this, the length of the tube is multiplied by its width.
It remains to calculate the number of tubes themselves. The working surface area is divided by the square footage of material in one roll and rounded up to the nearest whole number.

Example:

The width of the wallpaper is 50 cm (0.50 m), the footage is 15 m.

Room height - 2.7 m, parameters - 4 × 2.8 m, window and door of standard sizes.

4 × 2.7 = 10.8 (m2) - the area of one wall.
2.8 × 2.7 \u003d 7.56 (m2) - the area of \u200b\u200bthe other wall.
10.8 × 2 + 7.56 × 2 = 21.6 + 15.12 = 36.72 (m2) - total surface area for pasting.
0.50 × 15 = 7.5 (m2) - coatings in one roll.
36.72 : 7.5 = 4.8 (round up to 5)

Method number 2

The second calculation method is convenient to use in cases where the number of rolls of specific, pre-selected wallpaper is determined, and the space has a standard layout. It consists of the following:

The perimeter of the room prepared for pasting is calculated.
The resulting value (in linear meters) is divided by the width of the panel, the result is rounded up to a larger integer. Thus, it turns out how many strips of the selected coating will be required.
The length of the material in 1 tube is divided by the planned height of the canvases. The result is rounded down to the nearest integer, and the number of strips per 1 roll is obtained.
The total number of strips is divided by the value of the calculated sheets in each tube, the required number of rolls is obtained (rounded up).

Example:

The width of the wallpaper tube is 53 cm (0.53 m), the footage is 10 m.

Room height - 2.6 m, dimensions - 5 × 3.5 m.

(5 + 3.5) * 2 = 17 (m) - the perimeter of the room.
17: 0.53 \u003d 32 - the number of strips of material.
10: 2.7 = 3 - number of strips per tube (2.7 - taken with a margin).
32: 3 = 11 - the desired number of rolls.

Important! If the selected wallpaper requires adjustment of the pattern, then the length of the tube is divided by the sum of the height of the room and the rapport step (the distance in centimeters by which the canvas moves to match the image).

Note! The first calculation method sometimes causes difficulties when working with canvases that require fitting. The disadvantages of the second option, many masters include measurements "by eye" of window and door openings.

Preliminary calculation of finishing materials is recommended to be carried out as carefully as possible. The lack of wall coverings will slow down the repair work for the time spent on additional purchases. In addition, a mismatch in shades is possible, since different batches of the same type of wallpaper sometimes differ in color reproduction. The purchase of excess material entails an unjustified increase in repair costs.

Found an error. In the second method, when searching for the perimeter, the length is multiplied by the width, but it must be added.

Yana

And so it is with me. I calculate the number of wallpapers before buying a tutelka in a tyutelka. Maybe she already got the hang of it, or maybe she's just so smart. ) Most likely, the second, because I calculated correctly from the very first time.

Maria

I don’t know what’s wrong with me, but no matter which method I use, whatever I invent myself, I have never been able to accurately calculate the number of rolls per room. Either I forget to subtract windows and doors from the total footage, or I just miscalculate. The fact is that two or three rolls after the repair of the room I have stably remains. Fortunately, now almost any store can return the goods. This is the only thing that saves. Previously, the wallpaper either simply gathered dust somewhere on the mezzanine, or was given to friends.

Sergei

We use the second method, we calculate the required number of whole bands. But at the same time, you should not count too much on savings due to windows and doors, there may not be enough leftovers after cutting. Although if the wallpaper is glued by professional finishers, you can save money by making a strip of two parts, for example, behind a cabinet. So that you do not have to buy a whole roll because of one strip. Glued so that the seam with all the desire you will not find.
