Pattern Repeat Can Add a Third to Your Wallpaper Order
A 64 cm drop-match repeat on a 2.4 m wall can waste half a metre per strip — enough to change the roll count entirely.

Each strip must start at the right point in the pattern, so the usable length of a roll is not its full length but the number of whole repeats that fit into the wall height, multiplied by the repeat. The remainder is offcut.
Straight match wastes less than drop match, and free match — a random pattern such as grasscloth — wastes almost nothing. Always buy every roll from the same batch number, because dye lots differ visibly.
