What is Wallpaper Calculator?

▾

A wallpaper calculator determines how many rolls of wallpaper are required to cover a room's walls, accounting for door and window spaces and the pattern repeat that requires extra paper for alignment.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

How to Wallpaper Calculator

▾

1Calculate total wall area: perimeter × wall height
2Subtract door and window areas (approximately 2m² per door, 1.5m² per average window)
3Add pattern repeat waste: if repeat is 64cm and roll is 10m, you lose ~6% per drop
4Divide adjusted area by usable area per roll (roll width × usable length)

Worked Examples

▾

Example 1

Given:Room 4m×4m · height 2.5m · 2 doors · 1 window

ಫಲಿತಾಂಶ:7–8 rolls (standard 10m×530mm rolls)

Wall area ≈ 32m² net

💡

Pro Tip

Always buy one roll more than calculated — pattern-matching means you often cannot return to buy the same dye lot months later.
