How many rolls do I need for one room?
Measure the length and width of each room. That provides the scope of one room: 2 x length + 2 x width. If you know the ceiling height, you can calculate the amount needed looking at the table below.
There a wastage of 10% is already taken into account. For larger patterns (wallpaper with offset match), you might expect even more waste.
