Wallpaper Calculator
A wallpaper calculator determines how many rolls of wallpaper are required to cover a room's walls, accounting for door and window spaces and the pattern repeat that requires extra paper for alignment.
💡
Tip: Always buy one roll more than calculated — pattern-matching means you often cannot return to buy the same dye lot months later.
