Calculate Number of Wallpaper Rolls Required
If you would like advice on working out the number of wallpaper rolls needed for your space, we are here to help. Please ensure that you have all of the measurements noted down for each wall and that they are correct.
Instructions on How To Calculate Number of Wallpaper Rolls Required:
Wallpaper rolls are 10 Metres long, with a width of 61.5cm
Pattern repeat is the vertical distance between 2 matching design elements on a roll of wallpaper. You will find the pattern repeat of your chosen design detailed on the product page.
1. Measure the Wall
Measure the width and the height of each wall.
Example: Feature Wall 350cm width x 240cm high
2. Divide to Calculate Number of Drops
Divide your wall width by your wallpaper width (61.5cm) to work out how many drops you need.
Example:
Feature Wall 350cm / 61.5cm = 5.69 drops. Always round up to a whole number = 6 drops. Do this for each wall.
3. Pattern Repeat
To work out the pattern repeat allowance for each drop, divide the wall height by the vertical pattern repeat (on product design page)
Example:
Feature wall height 240cm divided by pattern repeat 30.75cm = 7.8 pattern repeats, round up to 8 pattern repeats @ 30.75cm = 246cm drop length required to match patterns
4. Multiply
Next you will need to multiply the number of drops needed (step 2) by the pattern repeat drop length (step 3).
Example:
Feature Wall 6 drops x 246cm pattern repeat drop length = 1476cm or 14.76metres
5. Calculate Number of Rolls Needed
Do this for all your walls and add together to get a total number of metres needed (step 4)
Divide this number by the roll length of 1000 cm (10 Metres) to work out how many rolls you need. Round up to the next whole number for the number of required rolls.
Example:
1476 / 1000cm (10 metres) = 1.48 rolls
Part rolls are not available, so round this up to 2 rolls required. It's always better to have more wallpaper than you need as if you are short and have to order another roll the colours might be slightly different.
