Wallpaper Roll Calculator
Estimate wallpaper rolls from wall dimensions, openings, pattern repeat, and roll type.
Limitations: American roll coverage is nominal (27 / 56 sq ft); European rolls vary by manufacturer. Textured and flocked papers often need more waste. Pattern-matched stripes use more than random prints.
What to do next: Always buy from the same batch / dye lot. For a large repeat (≥ 18 in), add an extra roll beyond this estimate. Prime new drywall with a wallpaper primer before hanging.
Planning estimate only. Verify roll width and usable coverage on the actual product label before ordering.
