Wallpaper Calculator

Use usable roll coverage

Wallpaper packaging can describe roll size in different ways, and pattern repeat can reduce usable coverage. Enter the usable square-foot coverage recommended for the specific product whenever possible.

Why include extra material?

Pattern matching, trimming, damaged strips, and future repairs can all require more wallpaper than raw wall area suggests. The calculator includes a selectable allowance for this.

Measure before buying

Measure wall height and room perimeter, then subtract major openings such as doors and windows. For complicated rooms or large patterns, verify quantities with the manufacturer or retailer before ordering.
