Wallpaper Calculator

How Much Wallpaper Do I Need?

Draw your room and get an instant, exact roll count — no manual maths, no under-ordering.

Open the wallpaper calculator

Free through pattern alignment. Takes about 2 minutes.

Quick roll estimate

Enter your total wall length and height for an instant estimate — standard 53cm × 10m roll, adjustable below.

Handles pattern repeat

Generic calculators just divide square metres. This one accounts for the extra waste a pattern's repeat distance actually costs you.

Any roll size

Not every roll is 53cm wide and 10m long. Enter the exact numbers from your own label and the roll count adjusts.

Room by room

Draw each wall, including doors and windows, and get a wall-by-wall breakdown — not one rough number for the whole house.

Got your roll count?

Turn it into a full cutting plan

The calculator gives you the number of rolls. A plan shows which strips to cut from each roll, how to align the pattern, and exactly where your offcuts can be reused — so nothing goes to waste.

Common questions

Is the wallpaper calculator free?

Yes — drawing your room and getting a roll estimate is free and stays free. You only pay if you want the exact cutting plan, workbench sheets and order list.

Does it work for patterned wallpaper?

Yes, and that's the part most calculators skip. Enter your pattern's repeat distance and the roll count accounts for the extra waste it costs you.

Do I need to create an account?

Not to use the calculator. An account is only needed to pay, and then it just needs an email address — no password.

Can I use a non-standard roll size?

Yes. Enter the exact width and length from your own roll label — the calculator is not locked to the 53cm x 10m standard.
