Our wallpaper calculator is based on coverage of 18 square feet per single roll of wallpaper with a 10% overage to account for any overhang and matching up of prints. Wallpaper is often sold in double rolls.

Each window is approximately 10 square feet and each door is approximately 20 square feet for estimation. These amounts are subtracted from the estimate.
