Simple Calculation Guide for Number of Rolls Required

 

Find The Surface Area Of A Wall

 

1. Measure the width and height of the wall in your chosen unit of measurement. (We use metres in this tutorial.)

2. Multiply wall width and height together =  _ m²  (Surface area of the wall.)

3. Repeat the steps for each consecutive wall that you wish to apply wallpaper to.

4. Add each figure together to get: ‘Total Wall Surface Area m²’

 How Many Rolls?

1. Divide the ‘Total Wall Surface Area’ by 5.2 (5.2 = m² coverage of one roll)

2. Round this number up the nearest whole number  i.e:  3.6 gets rounded to 4 rolls of wallpaper.

This is the minimum number of rolls you will need.

We always recommended that you order an extra roll of wallpaper than you need. This is to be certain you have enough wallpaper for trimming allowance and to account for any unexpected difficulties when hanging.

Many people store a roll of the wallpaper for potential future touch ups. Alternatively, any unused, unopened rolls of wallpaper may be returned.

 

 


Pattern Repeat

All of the wallpaper designs in the Surface House collection are a ‘straight match’. (See image below). Meaning the pattern matches at the same horizontal point on each strip of wallpaper; there is no ‘drop’ in the pattern.

This makes planning and applying the wallpaper easier for you and means that there is less wallpaper wastage overall.

      Wonderful! Thank you for reading and commenting. We really wanted to share the formula in the most simple and useful way for how to work out how many rolls of wallpaper are needed.
      The wallpaper calculators available online are great too, but they don’t always allow for custom areas such as doors and windows. We wanted to help people understand the method for working it out with easy to scroll through pictures.
      Thanks for reading!
