Buy too few rolls and you'll be hunting for a matching dye lot weeks later when the print has already been discontinued. Buy too many and you've wasted budget on rolls sitting in storage. Enter your room dimensions below for an accurate roll count, including waste for pattern matching.
Rolls Needed
How It Works
Room perimeter (2 × length + width) multiplied by wall height gives the total gross wall area to be covered.
Each door removes about 21 sq ft and each window about 15 sq ft from the area you actually need to paper.
The net area is inflated by 5-25% depending on pattern repeat, then divided by 57 sq ft per roll and rounded up.
Always round up to the next full roll, and if your budget allows, buy one spare roll beyond that. Wallpaper is sold in dye lots — if you run short partway through the job, matching the exact shade from a later batch (or a print that's since been discontinued) can be difficult, or impossible.
Common Questions
A standard European roll (about 0.53m wide by 10m long) covers roughly 57 sq ft (5.3 sqm) gross, before accounting for pattern matching waste.
Yes — large repeating patterns can waste 20-25% more material trimming each strip to match, versus about 5% for a plain or small-pattern design. This calculator adjusts for that automatically.
Yes, this calculator deducts a standard door (about 21 sq ft) and window (about 15 sq ft) for each one you enter, though unusually large windows or double doors will free up a bit more material than estimated.
Always round up and buy one extra roll if your budget allows. Matching a discontinued print or dye lot later can be difficult, and a spare roll covers future repairs.
Yes, taller walls need more wallpaper per linear foot, and very tall walls (over 9-10ft) may also mean more strips are cut from each roll length, slightly increasing waste.
