Wallpaper Roll Coverage
Estimate how many rolls of wallpaper you'll need by dividing total wall area by the coverage of a single roll.
Provides a basic estimate; always check roll specifications and allow for pattern matching.
Examples
- Wall area 30 m² ÷ Roll coverage 5 m² ⇒ 6 rolls
- Wall area 40 m² ÷ Roll coverage 4.5 m² ⇒ 8.9 rolls
