Nearly all wallpapers sold by the roll are 395.6 inches in length. You can find roll length on each Wallpaper product page in the product details section.
Most wallpapers are sold by roll. If your chosen wallpaper is sold by the yard, this will be clear on the product page.
Calculation based on:
  • We have allowed 4in per drop for trimming top and bottom
  • Assuming part widths may be used elsewhere.
  • We have not allowed extra for uneven or sloping walls
  • No reductions have been made for doors and windows - for large openings only you may wish to adjust your dimensions.
