How many wallpaper rolls do I need for a 12×15 room?
For a 12×15 ft room at 10 ft height with a 21-inch roll (33 ft long), you typically need 10–12 rolls depending on pattern repeat and number of openings.
What is a pattern repeat in wallpaper?
Pattern repeat is the vertical distance after which the design repeats. Higher repeat means more waste when matching patterns — add the repeat length to room height per strip.
Should I order extra wallpaper rolls?
Always order 10–15% extra for waste, pattern matching and future repairs — wallpaper dye lots vary and exact matches may not be available later.
