Wallpaper Roll Calculator
Estimate how many wallpaper rolls you need from wall width, wall height, roll size, pattern repeat, and waste. The calculator works best for straight walls before trimming around windows or doors.
Frequently asked questions
Why does pattern repeat matter?
A repeated pattern can force each strip to start at a matching point, increasing the usable length needed per strip.
Should I round up wallpaper rolls?
Yes. Buying short can be expensive because later rolls may come from a different dye lot.
Does this subtract doors and windows?
The MVP calculator keeps the estimate conservative and does not subtract openings.
