The One-Batch Wallpaper Order
Drops counted wall by wall, each roll's yield worked out for your paper's match with the worst case allowed, doors and windows credited only when the offcuts can carry them, every wall priced papered or painted, and one order, plus one spare, from one batch
DrainHouse's Wallpaper Calculator used to divide wall area by roll coverage, with no place for the pattern repeat, so on its own default room it said 7 rolls where the walls take 10. It now counts drops and adds one full repeat to every drop: a cautious rule that is never short, and that often orders rolls you will never open. Square feet hide the offcuts, the trim and the length lost lining up the pattern, and nothing on the free tool says what a door or a window really gives back, or that the roll you run short by comes from another batch. The One-Batch Wallpaper Order counts what you hang. In its worked example, a 13 by 11 ft bedroom with 9 ft walls and a 21 in straight-match paper on 20.5 in by 33 ft rolls takes 30 drops. The old area method bought 9 rolls, 3 drops short; the cautious rule says 15. Worked from the pitch the straight match demands (the drop rounded up to whole repeats) with up to one repeat lost lining up every roll, each roll gives 3 drops: 10 rolls to hang, 11 ordered with the spare, $212.50 less than the cautious order at an example $42.50 a roll. It then prices each wall papered or painted, orders once from one batch, and readies a dry, sound wall. Every figure is computed by the site's own calculator code, and every room, paper and price is an example to replace with yours; the trim allowance is called a rule of thumb, the lining-up loss a worst case. Safety lines are quoted from the EPA (mold up to about 10 sq ft, lead in pre-1978 homes, never mixing bleach with ammonia) and the CDC, with the circuit off at the breaker before any cover plate comes off and a licensed electrician beyond that. Included: 7 steps, 4 printable working pages, a drops-per-roll table for common heights and repeats, a quickstart, and a personalised sheet worked from the numbers you enter in the Wallpaper Calculator.
