How to measure walls for wallpaper and murals

Standard Wall

1, Measure the height and width of your wall/walls in cm or inches. If you are wallpapering more than one wall then add the total width together.
2, If the wall is a straight rectangle we recommend you measure the heights of both the left and right side of the wall as the two sides can often differ. Select the greater of the two heights.
Important: We recommend that you add an extra 5cm/2” to the width (each wall) and height to accommodate any variations i.e., wonky walls or incorrect measuring.
Measuring tips:

Square or Rectangle Walls

Multiple Walls

Measure the width of each wall (plus 5cm/2”) and then add that together. This is your total width. Then measure the height (plus 5cm/2”). You don’t need to order the wallpaper/mural as two separate parts.

Sloped Walls

Multi Sloped Walls

Customisable Wallpapers and Mural Measuring Tips

When ordering customisable wallpapers and murals, always:

  1. Provide exact measurements (width x height) in either cm or inches.
  2. Round any point or half measurements up.
  3. Measure both the left and right side heights of the wall as the two sides can differ then use the greatest measurement.
  4. Double-check you have provided the correct units (e.g., centimetres or inches)
  5. Add at least 5cm/2″ allowance to account for wonky walls!
