How to estimate the number of rolls of wallpaper you need:
- Measure ceiling height. For a room with a standard ceiling height of 2.5m, assume that you will get 3 drops to a roll. Please take into account that the number of drops per roll will decrease on walls over 2.5m in height.
- Measure the width of the wall.
- Divide the width of the wall by the width of the wallpaper (0.615m).
- Divide that number by 3 and you will get the number of rolls needed
Example with a 5 metre wide wall:
- Divide 5 by 0.615 (wallpaper roll width) = 8.13
- Divide 8.13 by 3 (number of drops per roll) = 2.71 rolls
- Therefore, purchase 3 rolls. Always allow for a little wastage.
