All About Wallpaper

Determine the square footage of your walls, and subtract any double doors or large window openings. Divide this number by the roll's square footage, reduced by a yield factor. This factor accounts for the waste, which increases as the pattern repeat gets bigger.

If PATTERN REPEAT = 0-6 inches, YIELD FACTOR = .83
If PATTERN REPEAT = 7-12 inches, YIELD FACTOR = .73
If PATTERN REPEAT = 13-18 inches, YIELD FACTOR = .67
If PATTERN REPEAT = 19-23 inches, YIELD FACTOR = .60
