FAQ
How is wallpaper calculated?
Divide wall perimeter by roll width to get the number of strips. Add allowance for patterned paper.
How do I convert to rolls?
Divide total strips by how many strips one roll yields (roll length รท wall height).
Are openings subtracted?
No, this is a generous estimate without subtracting windows/doors, which covers cutting waste.
Why a pattern allowance?
Patterned paper needs matching between strips, wasting some at the top. Usually 10-20%.
What roll width should I use?
Roll widths vary by region; adjust the type to match your product.
