How many rolls of wallpaper you need — the decorator's way. Offline.
How many rolls of wallpaper do I need? Wallpaper Calculator uses the strip (drop) method decorators
actually use — so you account for the offcut at the top of every drop, not just raw area.
Enter your room size, wall height and roll dimensions, and get the number of rolls to buy, plus the
strips needed and full drops per roll. Works in metric or imperial. Fully offline, no sign-up.
For DIY decorators and tradespeople papering a room without over- or under-buying.
