Frequently asked questions
How many m² does a wallpaper roll cover?
A standard roll 10 m long and 53 cm wide covers about 5.2 m². Pattern matching reduces the real coverage.
How much waste should I add?
Add 10-15% for cuts at corners, windows and pattern matching. The bigger the pattern, the more waste.
Calculating Wallpaper Rolls
Calculate the room perimeter (2 x length + 2 x width) and multiply by the height. Divide the total surface by the roll coverage and add 10% waste. Always round up.
