How much wall area does each roll of wallpaper cover?
One of the most important questions before buying wallpaper is how many meters of wall area does each roll of wallpaper cover?
Knowing the answer to this question will help you make an accurate and professional choice without additional costs or shortage of rolls.
Typically, each standard roll of wallpaper covers about 5 square meters of wall surface. Of course, this number can vary slightly depending on the height of the wall, the type of design and the installation method.
Standard size of each wallpaper roll
In the Iranian and global wallpaper market, most rolls are offered with the following standard dimensions:
- Roll width: 53 centimeters
- Roll length: 10 meters
Given these dimensions, the useful area of each roll is approximately 5 square meters, which is the basis for calculating the number of rolls required.

How to Calculate the Number of Rolls of Wallpaper
To calculate the number of rolls of wallpaper, just follow a few simple but precise steps.
Calculate the Wall Area
First, measure the width of the wall that is to be wallpapered and multiply it by its height:
Wall Area = Width × Height
At this stage, make sure that columns, corners, and all areas that are to be covered are included in the measurement.

Practical example of calculating the number of rolls
Assume:
- Wall width: 5.2 meters
- Wall height: 2.5 meters
The area of the wall is:
5.2 × 2.5 = 13 square meters
Now divide the area by the approximate coverage of each roll (5 square meters):
13 ÷ 5 = 2.6 rolls
In this case, the number is rounded up;
So for this wall, you will need 3 rolls of wallpaper.

Is the formula for calculating the number of rolls accurate?
Yes, this method is one of the most common and accurate formulas for calculating the number of rolls of wallpaper, provided that the measurements are taken carefully.
However, it is recommended to always have an extra roll. This extra roll will give you peace of mind in case of a mistake in cutting, damage during installation, or the need to modify the design.

Important Tips Before Buying Wallpaper
Basic Wall Measurements
Before buying, be sure to measure your walls carefully. Calculate the height of the wall without taking the cornice into account to get a more accurate number.

Coordination of the design and pattern of the rolls
In patterned wallpaper, the matching of the patterns between the rolls is very important. Mismatching the patterns can increase roll consumption.

Calculating Doors and Windows
Subtract the area of doors and windows from the total wall area. This will help you calculate the number of rolls needed more realistically and prevent you from buying more.
