Our wallpaper calculator makes all the allowances for you, such as pattern repeat & trim. So you know that the number of rolls calculated will be the number you need to order.
Calculation based on:
We have allowed 10cm (4in) per drop for trimming top and bottom
Assuming part widths may be used elsewhere.
We have not allowed extra for uneven or sloping walls
No reductions have been made for doors and windows - for large openings only you may wish to adjust your dimensions.
