How to calculate how much you need to wallpaper

From what depends on the number of wallpapers

From the size of the room (see below) and on the design. One roll is usually 10 meters. If the wallpaper plain and a ceiling height of 2.5 meters, you can cut the roll into four bands. If the picture will have to adjust, there will be three bands.

free docking

No alignment pattern: just roll is cut into the desired number of panels. Usually it is plain wallpaper with abstract pattern or vertical stripes.

Direct docking

Figure will combine horizontally so that adjacent strips start with identical elements. Here everything will depend on the height of the repeat - the distance through which the pattern is repeated (indicated on the label). In the worst case, it will have to throw away almost the full height of the repeat, so when calculating it should be added to the ceiling height.

ectopic dock

The image is positioned on the diagonal, so that each belt has shifted. Typically, half of rapport. In this case, the height of the ceiling need to add height and repeat the offset value: both numbers can be found on the label.

How to calculate the number of wallpaper with tables

This is the perfect way if the room is square or rectangularAnd the wallpaper does not require adjustment. Need a room area and ceiling height.

Calculating the number of narrow Wallpaper (Width - 53 cm, length - 10 meters).

Calculating the number of wide wallpaper (Width - 106 cm, length - 10 meters).

How to calculate the number of wallpaper mathematically

If the room has a complex shape, there are folds and niches, it is better to consider the perimeter. To do this, add up the lengths of the walls. Window and door openings of a width less than 60 cm equal to the flat wall, the wider excluded from calculation. The resulting value is rounded.

Example: 2.75 m + 3 m + 0,4 m + 2,85 m + 4 + m = 0.65 m 13.65 m ≈ 14 m.

Then it is necessary to determine the number of bands: divide the perimeter of the roll to width. Returning to our example 14 m / 1.06 = 13.2 m. Is rounded - 14 canvases wide wallpaper. To narrow Wallpaper: 14 m / 0.53 m = 26.4. That is 27 bars.

Now you need to determine how many strips can be obtained from a single roll: Roll length must be divided by the length of the strip. And there may be three options:

1. If the wallpaper does not require adjustment, the length of the strip is equal to the height of the ceiling. 10 m / 2,75 = 3,6 ≈ 3.
2. If the wallpaper straight docking, the strip length is the sum of the height of the ceiling and the height of the repeat (0.6 m). 10 m / (2,75 + 0,6) = 2,9 ≈ 2.
3. If the wallpaper is coincident with the dock, the strip length is the sum of the height of the ceiling height rapport (0.6 m) and the offset value (0.3 m). 10 m / (2,75 + 0,6 + 0,3) = 2,7 ≈ 2.

The last step is necessary to us the number of bands divided by the number of lanes on a roll. If the wallpaper will be wide, 14 should be divided into 2 or 3. If narrow, divided into 3 or 2 will have 27 lanes.

How to calculate the number of wallpaper using the services and applications

The quickest way, if you know the room, and the easiest, if not friends with math. In many web calculators wallpapers are just a few good-quality.
