Many online wallpaper calculators do not factor in repeat patterns and half drops. We highly recommend you follow the following calculation to work out how much wallpaper you require:

 

 

First things first

Eyvi wallpapers are 52cm wide and 1005cm (10.05m) long. You will also need to know the following for your chosen design:

  • The vertical pattern repeat in cm
  • Whether the design repeat is straight or a half drop

This information is available on each product page.

 

Step 1. Measure the Wall

Measure the width and the height in cm. If the walls have the same heights you can add the widths together. If not, work out one wall at a time.

Example wall: 400cm wide x 240cm high

 

Step 2. Work out the drops

Divide your wall width in cm by 52cm. Then round up to the nearest whole number.

Example: wall width 400cm divided by 52cm = 7.69

Rounded up = 8 drops

 

 

Step 3. Multiply drops x wall height

Example: 8 drops x 240cm = 1920cm

 

Step 4. Add the pattern repeat

Add a pattern repeat length for each drop, apart from the first one.

Example (imagining the pattern repeat is 70cm):

7 drops x 70cm = 490cm

 

 

Step 5. Factor in for a half drop

If the wallpaper is a half drop design, then you need to add half of your total pattern repeat again (if it is straight drop you do not need to add anything else).

For example: 490cm divided by 2 = 245cm

 

Step 6. Add up and round up 

Example:

Drops x wall height: 1920cm

70cm repeat: 490cm

Half drop: 245cm

TOTAL: 2655cm

Round up to the nearest 1000CM = 3000cm

= 3 x 1005cm/10.05m rolls required

 

Step 7. Measure twice – order once!

Yes! Repeat the above measuring and calculating to be absolutely sure of your calculations. 

Each batch of wallpaper ordered may differ ever so slightly, so it is important to order the correct amount up front.
