Our free wallpaper calculator takes the guesswork out of ordering by automatically allowing for pattern repeat and trimming, so you can order with confidence knowing you have the correct number of rolls.
Before ordering wallpaper, measure the full width of each wall you plan to cover and the height from floor to ceiling. Include doors and windows in your measurements, as wallpaper is usually hung across the entire wall.
Enter your dimensions into our wallpaper calculator and we'll work out the correct number of rolls, including allowances for pattern repeat and trimming. This helps ensure you order the right quantity for your project.
Enter your measurements and wallpaper details below and the calculator will tell you the amount of wallpaper required.
