What wallpaper for a 12×12 room costs
Double rolls run $30 to $80 for mainstream papers and $100 to $250 for designer and grasscloth lines, so this room is $300 to $800 in ordinary paper with no repeat, or $300 to $800 with a 24 in repeat. Paste for 10 rolls is about $45; pre-pasted and peel-and-stick papers need none. A paperhanger charges roughly $1.50 to $3 per square foot, or $501 to $1,002 for the 334 square feet of wall here, more for large-repeat patterns that need careful matching. Painting the same walls instead takes about 2 gallons; see the paint calculator for a 12×12 room.
Hanging paper in a 12×12 room
- Buy all 10 rolls at once and check that every label shows the same batch or dye lot number.
- Start on the wall opposite the door and work both ways; the last seam, where the pattern will not match, lands in the least visible corner.
- Each strip is cut to 100 in without a repeat; with a 24 in repeat, 120 in. Number the strips as you cut them.
- Prime bare or patched drywall with wallpaper primer first, or the paper will take the drywall face with it when it comes down.
- One extra roll is cheap insurance; a replacement from a later batch rarely matches.
