Method
Retailers disagree about subtracting openings, and the disagreement is real. When deducting is safe, when it quietly under-orders patterned paper, and what the calculator does by default.
가이드 읽기Reference
Nine rolls, under stated assumptions. A room-size chart from a powder room to a large living room, with the drops behind every number and the four things that change it.
가이드 읽기Method
Measure the walls, read the label, pick the match, and count drops instead of square feet. The method installers use, worked on a real room, with the area shortcut shown beside it so you can see where it under-orders.
가이드 읽기Buying
Why American wallpaper is priced by the single roll and sold by the double, what each one actually holds, and how to avoid ordering half or twice what your walls need.
가이드 읽기Units
Why wallpaper comes in two unit systems, what a 53 cm × 10 m roll and a 27 in × 27 ft double roll each hold, the conversions you actually need, and which calculator to use.
가이드 읽기Pattern
