How much wallpaper will your room need?

Each wall’s width is rounded up to whole vertical strips. A cutting allowance is added to each wall’s height, followed by one full pattern repeat for straight match, or one repeat plus half a repeat for half drop. This follows our conservative planning method; your installer may plan the cuts differently.

For rolls, the estimate uses the tallest adjusted strip across all walls and counts only whole strips per roll—no horizontal joins. For material supplied by length, the adjusted strip lengths are added together and rounded up to a full yard or meter. Supplier minimums and increments are not included.

Before committing to material: ask our team to verify the specification, batch, match and layout. This tool is not suitable for custom murals, pre-cut panels, unusually shaped walls, or products with special cutting instructions. It does not deduct doors or windows, promise a final order quantity, or price installation.
