How to Calculate Wallpaper Rolls
Measure the room perimeter and wall height to get gross wall area. Subtract doors and windows. Add 10% for waste/pattern matching.
Formula
Net Area = (Perimeter x Height) - Doors/Windows
Rolls = ceil(Net Area x 1.10 / Coverage Per Roll)
हल किया गया उदाहरण
52 ft perimeter, 9 ft walls, 40 sq ft doors/windows, 56 sq ft rolls.
- 01Gross wall area = 52 x 9 = 468 sq ft
- 02Net area = 468 - 40 = 428 sq ft
- 03With 10% waste = 428 x 1.10 = 470.8 sq ft
- 04Rolls needed = ceil(470.8 / 56) = 9 rolls
