🖼️ Wallpaper Calculator
Calculate the number of wallpaper rolls needed based on room dimensions and pattern repeat.
How to Calculate Wallpaper Rolls
Measure the perimeter of the room and multiply by the wall height to get total wall area. Subtract doors and windows. A standard single roll covers about 35 sq ft, but pattern repeats can increase waste by 15-25%. Wallpaper is typically sold in double rolls, which cover about 56-70 sq ft.
