How much wallpaper do I need?

 

Our wallpaper calculator requires you to input some data first. It includes the following values:

  • Room dimensions: you need to type in the length, width, and height of the room. If your room has a different shape that a rectangular cuboid, you can also input the surface area directly. We recommend that you measure the height of your room anyhow if you want to include pattern repeat into the calculations.​​​​​​​

  • Doors: you can leave the default dimensions of doors or customize them. Once you will type the number of doors in, the wallpaper calculator will find their area automatically.

  • Windows: again, you can choose the default dimensions or type in custom ones. If you have windows of different sizes in your room, you can also calculate the total area manually and input this value into the appropriate box.

  • Adjusted height: this is the actual length of wallpaper you will need to use per stripe to account for the pattern repeat.
  • Adjusted room area: takes into consideration both the pattern repeat and openings.
  • Number of rolls: the total number of wallpaper rolls you need to buy. This number is always rounded up.
  • Total cost: the total amount of money you need to pay for your wallpaper.

  • How accurate is the result?

    ​​​​​​​

    Even though the result is most accurate when it comes to the pattern repeat, you should add 10% of additional wallpaper to account for complicated fittings or for trimming. If the shape of your room is very complex, you should consult your decorator prior to the wallpaper purchase.
