How Wallpaper Roll Quantities Are Calculated
This calculator estimates the number of wallpaper rolls needed to decorate a room. It divides the total wall area by the usable area per roll (accounting for pattern repeat). Formula: Rolls = Total Wall Area ÷ Usable Area Per Roll. Inputs: room width, length, and height, plus the number and size of windows and doors to deduct. Outputs: number of rolls required with a 10% safety margin.
