Checklist
To double check your wallpaper quantities which is always best practice. You can also work out how many rolls for your wall manually.
So all you need is; a measuring tape and the details of the wallpaper you have chosen.
Once you have measured the width and height of the wall what you are going to do is work out how many drops of wallpaper you need to cover your wall and how many drops you can get off your chosen roll. See below case study to better explain:
Wall is: 5m wide by 2.4 high
Roll is: 52cm wide by 10m long
52cm goes into 5 = 10 times (10 drops needed across the wall length)
10 divided by 2.4 = 4.1 (rounded to 4 drops in a roll)
10 divided by 4 = 2.5
Rounded up to 3 rolls to order
Doors, windows etc.
If your wallpaper has a pattern, like in the image above, you will need to ignore the door (or window) opening. This is because the pattern will need to seamlessly carry on over the opening. The wallpaper that is cut away for the opening is classed as wastage. If you do not allow for this you may run out of wallpaper.
If your wallpaper doesn’t have a pattern repeat like the example below. You may be able to use offcuts off the roll for a small panel above a door or window. But you will need to check there will be offcuts available. For example if your ceiling height, or drop, is 2.5 metres and the roll size is 10 metres you will not have any offcuts as you will use exactly 4 drops, using all the available wallpaper on the roll.
