Generally, in order to calculate how much wallpaper you need, use the following steps:

- First, calculate the wall area by multiplying the height of the wall by the width. View our “How to measure my walls? if you are unsure.
- Second, calculate the area of the wall you will not be papering (i.e. windows and doors) by multiplying the height by the width of each area you will not paper.
- Third, minus the unpapered area from the area of the wall. This will give you the wallpapering area.
- Fourth, divide the wallpapering area by the square footage of the wallpaper you would like to purchase. This will give you the total number of rolls needed to complete your project. However, you will need to consider extra paper for the pattern repeat and extra trimmings.

To make this process easier for you, send us your dimensions (height & width) and we can work out the number of rolls you will need to order for your project. We’ve taken the design repeat into consideration when calculating how many rolls you will need.

Alternatively, use the online roll calculator from one of our suppliers to determine the number of rolls required:
