How to get your Wallpaper measurement? ( Width x Height )

1. Types of Korean Wallpaper

Our Korean wallpapers measure either
– 1.06m x 15.5m or
– 0.93m x 17.75m

1 Roll of wallpaper can covers up to 12.5 square meters of space.


2. Formula ( Measurement in meters )
Measure the width & height of your wall first, then multiple them together to determine the total square meter needed for your wall. You will need just 1 roll of wallpaper if the calculation is not more than 12.5 m². If it is more than 12.5 m², you will need 2 rolls or more.

Example 1 –
Wall is 6m (W) x 3m (H) = 18 m²
18  /  12.5 = 1.44   ( You will need 2 rolls )

Example 2 –
Wall is 9.5m (W) x 2.7m (H) = 25.65 m²
25.65  /  12.5 = 2.052   ( You will need 3 rolls )


You can add up the measurement for 2 or more walls Only if they are all using the same wallpaper design.

Example 3 –
Wall 1 is 5.5m (W) x 3m (H) = 16.5 m²
Wall 2 is 3.5m (W) x 2.8m (H) = 9.8 m²
Wall 3 is 3m (W) x 3m (H) = 9 m²
Total – 16.5 + 9.8 + 9  =  35.3 m²
35.3  /  12.5 = 2.824   ( You will need 3 rolls )

You will have to take each individual measurement, if you are using different wallpaper design for each wall.


3. Take Measurement ( width & height including all windows & doors )
Please measure your doors & windows as well so that you will not get caught running out of wallpaper during installation.
