Before buying your wallpaper, you need to work out the number of rolls necessary for your room without any waste. The calculation depends on the wallpaper you choose. You do have to take into account a possible repeat which will have to be added to the height of the strips.
If the wallpaper is plain or if the patterns do not have to match from one strip to another, you do not need to take the repeat into account.
If the wallpaper has a straight match (the patterns repeat themselves on a horizontal line) or a half drop (the patterns repeat one lay out of two), you need to add the length indicated on the roll label to the height which you have measured when calculating the strips (from the skirting board to the ceiling).
We suggest a simple calculation to work out the number of wallpaper rolls you need for yours walls:
When you buy your wallpaper, please check carefully the batch number of each roll to avoid having tone differences in the same colour. In the case of plain wallcoverings, please check on the label if you have the symbol ↑↓ in order to follow this particular hanging instruction. Please think also of keeping the remains of rolls already opened…just in case you have an accident whilst hanging as you might not necessarily find the same pattern for small repairs.
