Wallpaper roll calculator
Estimate rolls from dimensions and pattern repeat assumptions.
كيفية استخدام Wallpaper roll calculator
The Wallpaper roll calculator estimates rolls from total wall width, wall height, roll width and roll length, with a pattern repeat and extra trim per strip. Each strip is the wall height plus trim, rounded up to whole pattern repeats. It works out how many strips the wall needs and how many full strips one roll gives, then rounds rolls up.
- Enter the requested values in the settings panel.
- Adjust the basic settings, then open Advanced mode for export and fine-tuning options. Custom settings stay active when the panel is closed.
- Run wallpaper roll calculator, review the output, then use the available copy or download controls.

Local bounded calculations. Numeric inputs must be finite and within the visible ranges. Lists and tables have operation-specific limits. Models, estimates and supplied rates must be checked against your intended use.
الأسئلة الشائعة
How many rolls of wallpaper do I need?
Enter the total width of the walls, the height and the roll size. With the defaults of 12 m wide, 2.4 m high, 0.53 by 10 m rolls, a 0.32 m repeat and 0.1 m trim, you need 23 strips, 3 per roll, so 8 rolls.
How does pattern repeat affect wallpaper quantity?
Each strip is rounded up to a whole number of repeats so the pattern lines up. A 2.5 m strip with a 0.32 m repeat becomes 2.56 m. Set the repeat to 0 for paper with no pattern to match.
Why does the calculator say one roll cannot supply a full strip?
The roll length is shorter than a single strip, including trim and pattern repeat, so no complete strip fits. Check the roll length and wall height, or choose a longer roll.
