Wallpaper Roll Calculator

So you’ve picked your perfect wallpaper from our range of top-branded value and designer wallpapers and now you’re ready to buy. But how many rolls of wallpaper do you need? Use Home Flair’s Wallpaper Roll Calculator to find out the quantity you should add to your basket.

Grab a tape measure and make a note of the height and width of each wall you need to cover in feet or metres, as well as the dimensions of any windows, doors or other areas that don’t need covering. Calculate the square area of the non-covered spaces by multiplying the height by the width.

Disclaimer: Please note that this tool should only be used as an estimate on the amount of rolls you may require, it provides your estimate based on a standard rolls coverage, excluding matching. For any advice feel free to contact us, or call 0161 729 1686.

NB. A standard door measures approximately 0.8 m x 2.0m or 1.6 sq m (2 ft 7" x 6 ft 6" or 20 sq ft). A standard window is about 0.9 m x 1.2 m or 1.1 sq m(3 ft x 4 ft or 12 sq ft).

Our standard wallpapers come in rolls of approximately 10.05 m or 33 ft (11 yd) long and 0.53 m or 1 ft 10" (21 inches) wide.

It’s always best to be on the safe side as repeat purchases cannot be guaranteed, so if you order too much and end up with some rolls leftover, we’d be happy to refund* you. A restocking fee may apply, see our FAQ Returns page for more information.
