Wallpaper Calculator

Work out how many wallpaper rolls you need — using the real strip-based method that accounts for roll size and pattern repeat — with U.S. pricing, a pattern-repeat comparison, and a downloadable PDF shopping list.

Pattern repeat drives waste — a large repeat can add several rolls. Always buy from the same dye lot and keep a spare roll. Estimates use 2024-2025 U.S. prices. For planning purposes only.
