# How much wallpaper do I need?

• Measure the width and height of one wall in metres.
• Multiply the height and width together to get the total in metres squared (m sq)
• Repeat the above steps for each wall you wish to wallpaper.
• Add together the m sq of each wall to get your room total area.
• Use the same process to calculate the total area of doors and windows.
• Subtract the total area of windows and doors from the the room total.

Account for Pattern Repeats
• Wallpaper with a pattern requires an extra step to estimate the number of pattern repeats for the wall height of your room. The higher the number, the more wallpaper you will need, while the smaller the number, the less wallpaper you will need.
• 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 2.8m high wall, and a wallpaper with a pattern repeat of 60.84cm (0.6084 m), then you will divide 2.8 by 0.6084. That will yield 4.60 repeats, which you will then round up to 5 repeats.
• Therefore, should you then buy a 10m roll of wallpaper of this wallpaper, there would be 16.44 repeats in the roll (10m divided by 0.6084). On this basis, you would be able to get 3 drops out of this wallpaper for this ceiling height.

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