Wallpaper calculator

Use this handy calculator to estimate how much wallpaper you'll need, in three easy steps!

Enter the dimensions of the area you want to wallpaper, then define the sizes of the windows and any areas you do not wish to cover. Select the number of doors the room has, then click the calculate button to receive the result. Please note, if your chosen style of wallpaper has a longer pattern repeat, you should consider buying extra to ensure you don't run out. In addition, when buying your wallpaper be sure that each roll has the same batch number, however if ordering your wallpaper from diy.com we will do this for you.
