How do I calculate how much wallpaper I need? All you need for your wallpaper calculator are basic data including: Room Dimensions You need the usual width, length, and height of the room. If you have a room with a different shape other than the rectangular cuboid, you can solve the area of the shape and input this directly into the calculator. Doors and windows You can either leave the default dimensions of doors and windows or customize them. Once you enter the dimensions into the wallpaper estimator, their areas are automatically calculated. Once you have gathered and typed in all these values, the wallpaper calculator with repeat solves the following for you: Adjusted Height Adjusted Room Area Number of Rolls Total Cost

How do you calculate wallpaper needed for a pattern repeat? Wallpapers without patterns are easy to install and calculate. Most wallpapers have a pattern or design and they require more materials than their solid counterpart. It’s also a good practice to retain some wallpaper in case some pieces get marked or damaged.
