How Many Rolls of Wallpaper Do You Need?
To find wallpaper rolls, multiply your total wall length by height for the wall area, add the pattern allowance, then divide by the usable coverage of a roll, about 56 square feet for a US double roll. A 360 square foot wall with a small pattern needs about 7 to 8 rolls. The calculator uses your actual roll coverage and pattern repeat for an accurate count.
Single Roll or Double Roll?
US wallpaper is usually priced as single rolls but packaged and sold as double rolls, which are easier to hang with less waste. The coverage figure to use is the usable area of the package you buy, so check whether your coverage is for a single or double roll. The calculator works with whichever coverage you enter, so match it to your product to avoid ordering short.
