Wallpaper quantity calculator

Use our handy wallpaper calculator to work out how many rolls of wallpaper you'll need to order for your walls. The calculator makes all the right allowances, such as pattern repeat & trim, so just measure and input your numbers and away you go!

Enter your measurements and wallpaper details below and the calculator will tell you the amount of wallpaper required.

Add up the width of all walls to be covered, at their widest point. Example: 380cm + 450cm + 380cm + 460cm = 1670cm
Measure from top of skirting (if applicable) to ceiling or coving.
Pattern repeat affects quantity required. You can find it on each wallpaper product page in the product details section.
The standard roll width is 52cm, but this can vary. You can find the width of your chosen wallpaper on the product page in the product details section.
Nearly all wallpapers sold by the roll are 10.05m in length. You can find roll length on each Wallpaper product page in the product details section.
Our calculations are based on:
  • Allowing 10cm (4in) per drop for trimming top and bottom
  • Assuming part widths may be used elsewhere
  • We do not allow extra for uneven or sloping walls in our calculations
  • No reductions have been made for doors and windows - for large openings only you may wish to adjust your dimensions to suit
