Wallpaper for a 10 × 12 room
Short answer
A 10 × 12 ft room with an 8-ft ceiling needs about 7 rolls of wallpaper (standard US double rolls) — that's 19 full-height strips covering roughly 301 sq ft of wall after doors and windows. Pattern-repeat rolls need a little more.

Wallpapering a 10 × 12 room
A 10 × 12 ft room with an 8-ft ceiling has about 44ft of wall to cover. At a 27-inch roll width that's 19 vertical strips after one doorway, and a standard US double roll yields roughly 3 full-height strips — so plan on about 7 rolls for a plain paper. A pattern repeat means fewer strips per roll, so add one or two more. Always buy a spare from the same batch.

Should I add extra for a pattern repeat?
Yes. A straight or drop (offset) match forces every strip to start at the same point in the pattern, so each drop rounds up to a whole repeat and you get fewer strips per roll. The calculator adds this automatically once you enter the repeat.
