Wallpaper Calculators

Wallpaper Calculator

Estimate Your Wallpaper Materials

Wallpaper estimation requires accounting for roll coverage, pattern repeat waste, and the confusing single-vs-double roll convention. The Wallpaper Calculator takes your room dimensions (including doors and windows to subtract) and returns roll counts for both US and European roll standards. Enter a pattern repeat value and it automatically adds the extra material needed for pattern matching.

Wallpaper goes on drywall (or plaster) surfaces. If you're choosing between wallpaper and paint, the Paint Calculator can estimate the alternative. For rooms with mixed surfaces — wallpapered walls and tiled backsplash — use the Tile Calculator for the tile portion.
