Calculate Wallpaper

Now that you've chosen the cutest wallpaper ever to put in your home, here's a guide to Calculating the Quantity of Wallpaper you need to apply.

The first thing to do is take the measurements of the wall , measure the height and length of the wall where you want to apply the wallpaper.

To calculate the amount of wallpaper for a wall that is 2.50 meters high and 4.00 meters long, we need to know the area of ​​the wall we want to cover.

To calculate the area of ​​the wall , do the height times the length (Alt x Comp):

2.50 x 4.00 = 10 square meters (10m2)

When arriving at the final measure of the wall area, it is suggested that you always count on an additional 10% of the total wall area , since there are always adjustments and waste.
Thus, the total area of ​​the wall must be considered as 10 square meters plus 10% of that area, that is, 1 square meter, which gives a total of 11 square meters.

Knowing that the total area of ​​the wall is 11m² , we then need to know the area of ​​the wallpaper roll, so that we can calculate the number of rolls needed to cover the wall.

The most common measure of wallpaper rolls is 10 meters long by 50 centimeters, so the wallpaper area is calculated: 10.00 x 0.50 = 5.00m²

Thus, it is already known that the wall is 11m² and a roll of wallpaper is 5m². Next, divide the area of ​​the wall by the area of ​​the wallpaper:

11 / 5 = 2.2 rolls

Since the account must always give a certain number of rolls, in this case 3 rolls of wallpaper are needed to cover the total area (including hits and waste).
