ABOUT PAPERROLL
A simple model.
A visible shopping plan.
Paperroll is a free, independent wallpaper roll calculator for measurements in centimetres.
What it does
The planner counts full-width drops for each wall, adds your total trim to one shared height, rounds cuts to an entered repeat, and counts how many full cuts fit each roll. It combines those same-length drops into a whole-roll order, then adds any extra rolls you select.
Optional price and transport inputs produce a quoted order cost. Missing prices are not replaced with retailer estimates. You can print or download the full calculation locally.
Where the model stops
All wall rows use one height and all rolls use one product. The planner does not subtract openings, reuse narrow strips or short tails, plan offset matches, or calculate initial pattern-alignment losses and corner overlaps. The guide explains the assumptions using original arithmetic examples.
Your product decides
Starting dimensions are illustrative. Read your roll’s actual dimensions and hanging instructions before entering values. Paperroll does not recommend a wallpaper or promise an installation quantity.
