Estimate wallpaper rolls
Wallpaper estimates depend on wall area, roll coverage and extra material for pattern matching. Enter wall width, wall height, roll coverage and waste percentage to estimate how many rolls to buy. It is useful for accent walls, full rooms and quick renovation planning.
Pattern repeat buffer
Large pattern repeats can require extra rolls, so increase the waste percentage when alignment matters.
Frequently asked questions
What is roll coverage?
Roll coverage is the square feet one roll can cover, usually shown on the wallpaper label.
Should I subtract windows?
For rough estimates, many people leave small openings included as a buffer. Subtract large openings if needed.
Why are rolls rounded up?
Wallpaper is bought in whole rolls, so the estimate rounds up.
