Wallpaper Calculator
Estimate how many rolls of wallpaper you need for any room.
You'll need
Pop in the wall and roll sizes and we'll do the maths.
How it works
We calculate how many full-height drops you can cut from one roll, then divide the total drops needed by drops per roll to get the number of rolls.
Always order 1–2 extra rolls — pattern matching and mistakes can leave you short, and dye lots vary between deliveries.
