How to measure wallpaper

Everything you’ll need to help you hang wallpaper like a professional

Everything you’ll need to help you hang wallpaper like a professional

You don’t want to find out mid-task that you’re short a roll or two or be left with lots of spares at the end, so check out our great guide to measuring your room and calculating how many rolls of wallpaper you’ll need to complete your new look.


Step 1: Measure your room

Step 1: Measure your room

Using a metal measuring tape if you have one, measure the total perimeter of your room (or the area you want to wallpaper) in metres, including any doors and windows. Divide this measurement by the width of the wallpaper you’re buying, e.g. if the area you want to cover is 10m wide and the wallpaper is 0.53m wide, divide 10 by 0.53.


Step 2: Calculate how many rolls you need

Step 2: Calculate how many rolls you need

Take the height measurement of the room/area in metres and multiply it by the number of widths needed. Divide that number by the length of the wallpaper roll – usually 10m – and you’ll have the number of rolls needed.

Here's an example:

2.4m (height of room) x 19.2 (room width ÷ by wallpaper roll width) = 46.08

46.08 ÷ 10m (length of the wallpaper roll) = 4.6

Total Rolls Needed:

We recommend getting a couple of extra rolls especially if your wallpaper has a repeating pattern on it. You can always return unopened rolls later.

If you haven’t got a calculator to hand, apply your measurements to our handy table below and it’ll do the work for you. It could also be a welcome second opinion on your calculations.
