Wallpaper Roll Calculator with Pattern Repeat

Enter wall width, wall height, roll size, and pattern-match details to estimate wallpaper rolls for free match, straight match, or drop match installations.

Job Reference

Optional job details for saved calculations, CSV, and print. These fields do not change the roll calculation.

Wallpaper Roll & Pattern Match

Enter the dimensions and pattern information from the roll label. No standard roll size or pattern repeat is preset.

Optional whole extra rolls. No reserve amount is added automatically.

How it calculates: For straight or drop match, each strip length is rounded up to the next full pattern repeat. For drop match, the entered offset alternates on every other strip.

Wallpaper Areas

Enter the total wall width and wall height for each area. Add separate areas when wall heights differ.

Doors and windows: This calculator works by wallpaper strips, not net square footage. Openings are not automatically deducted. Enter the wall width you want to cover with full strips.
