Wallpaper, Little Greene Sakura Petal, offcuts

My guess is that the offcuts are about the equivalent of a full roll (but with joins).

The wallpaper calculator on the Little Greene site suggests 1 roll for walls up to 1.4m wide with standard ceilings of 2.6m high. For walls that are 1.5-2.9m wide with standard ceilings, they suggest 2 rolls. So if you bought both the offcuts and the full roll we have, their calculator suggests you would be able to do up to 2.9m width of wall with standard 2.6m ceilings. Because of the offcuts, you might need to have a join mid-wall.

If you're looking to paper above panelling or above tiles, then you would not need as much, because the height would be less. If your ceilings are higher than standard, you would need more.

The wallpaper calculator is here https://www.littlegreene.ie/sakura-petal. Under ?Buy this wallpaper?, it says ?How much wallpaper will I need?? If you click on that, you can put in the measurements of your room.
