Construction/ CALCULATOR
Wallpaper area and roll quantity
Estimate wall area and whole rolls using the product’s effective coverage after pattern matching.
Total the lengths of walls receiving this wallpaper.
Use the required cut height, including intended trimming where appropriate.
Subtract only large areas that will not consume strips or offcuts.
Pattern repeat, corners and future repairs can increase the allowance.
Use supplier coverage adjusted for roll width, cut height and pattern repeat—not raw roll area.

Area-based planning using an effective roll coverage already adjusted for usable full-height drops and pattern matching. Small openings may not reduce roll demand because strips and matching still consume material. Batch, wall defects and special features are excluded.
