 How Much Wallpaper Do I Need?

Step 1: Calculate the number of rolls needed
- Measure the width of each of the walls you want to cover in your room and divide by 53cm (the standard width of wallpaper, check wallpaper width first!).  This will give you the number of rolls.  
 
Step 2: Calculate the length of wallpaper needed
- Measure the height of your room and multiply the height by the number of drops to get the meter age needed.  
 
Step 3: Calculate the number of rolls needed
- Divide by the length of the roll less the stated pattern repeat.  Wallpaper is normally 10m long but checks your wallpaper length first!  Round up to the nearest whole number.  This will give you the number of rolls needed. 
 
Step 4: Allow extra for any wastage.
- Personal choice.  I always purchase at least 1 additional whole roll but sometimes more if it is a big or challenging room.  Consider how difficult the walls are, how skilled you are at wallpapering / DIY, how much or little you rounded up in Step 3.
  
Example
So, for a wall that is 5m wide by 2.5m high, using wallpaper which has a 64cm pattern repeat the calculation would be:
 
Step 1: Calculate the number of rolls needed
- 5m (wall width) divided by 0.53m (wallpaper width) = 9.4 drops
 
Step 2: Calculate the length of wallpaper needed
- 9.4 drops x 2.5m (room height) = 23.6m
 
Step 3: Calculate the number of rolls needed
- 23.6m divided by 9.36* (*10m (wallpaper length) - 0.64m (pattern repeat)) =  2.5 rolls.  Rolls are sold in whole lengths so this rounds up to 3 complete rolls.
 
Step 4: Allow extra for any wastage.
- Personal choice
