How to Measure Walls for Wallpaper:
1:Measure Height & Width: Measure each wall’s height and width (in meters/feet).
2:Calculate Total Area: Multiply height by width for each wall, then add all walls together.
3:Subtract Openings: Deduct areas of doors, windows, or other non-covered sections.
4:Add Extra: Include 10% extra material for trimming and future repairs.
Example: A 3m x 4m wall = 12㎡. For 4 walls (48㎡), subtract 2㎡ for a window → 46㎡ + 10% = 50.6㎡ total.
