How to Calculate Wide Width Wallpaper

Many wide-width wallpapers are sold by the metre. Below we have detailed the best way to calculate the amount needed for your space.

1. Calculate the number of drops you will need to cover the wall

We have shown as example below with Elysium Wallpaper – Storm.
You will need to measure the width of the wall and divide it by the width of the wallpaper.

550cm ÷ 140cm = 3.92

Round this figure up to the nearest whole number.

In this case, you will need 4 drops of paper to cover the wall.

2. Calculate the number of repeats per drop of wallpaper

Measure the height of the wall and divide it by the vertical pattern repeat of the wallpaper.

245cm ÷ 73cm = 3.35

Round this figure up to the nearest whole number, in this case 4.

3. Calculate your final drop length

You will need to multiply the number of vertical repeats from Step 2 by the vertical pattern
repeat.

4 x 73cm = 292cm

The drop length you will need will be 292cm

4. Calculate your meterage

To calculate the final meterage multiple the number of drops from Step 1 by the final drop length from Step 3.

4 drops x 292cm = 11.7 metres

We recommend adding 10% to your total meterage to allow for any mistakes plus one extra repeat to allow for positioning of the pattern on the wall.

5. Calculate a whole room

Imagine the room laid flat, ignoring doors and windows as per the diagram to the left.
In the diagram there are 4 walls which total 18.4m

(550 + 370 + 550 + 370cm)

Therefore divide 18.4m by 140cm (wallpaper width) = 13.14 rounded up to 14 drops required to paper this room.
So in this example the final meterage to cover all 4 walls will be:

14 drops x 292cm (drop length) = 40.8m

This would round up the next whole number, 41 metres.
