How much wallpaper do I need?

Here are some steps to follow to help you calculate how much wallpaper you may need.

Account for Pattern Repeats
  • Wallpaper with a pattern requires you to estimate the number of pattern repeats for the wall height of your room. 
  • Find out how often the pattern repeats and then divide the height of the wall by the cms between the patterns. If you don't end up with a whole number, then round up.
  • For example, if you have a 2.24m high wall, and a wallpaper with a pattern repeat of 40.61cm (0.4061 m), then you will divide 2.24 by 0.4061. That will yield 5,52 repeats, which you will then round up to 6 repeats.
  • Should you then buy a 10m roll of wallpaper of this wallpaper, there would be 24.62 repeats in the roll (10m divided by 0.4061). On this basis, you would be able to get 6 drops out of this wallpaper for this ceiling height. 

Using the same information as above, the example below shows how you can visually calculate how much wallpaper you need. I always find it easier to actually draw it out on a piece of paper, and then I can see how much i need.

The below example is for a small toilet/powder room. I have not marked on doors or windows, so any calculation will be the maximum amount you will need.

The room measures 152cm across by 124cm wide, and the floor to ceiling height is 224cm.

You will need = 3 rolls of wallpaper.

I hope this helps and if you need any assistance, please do not hesitate to get in touch.
