Calculator

Wallpaper calculator

Choose the roll, then enter the wall's width and height. The calculator cuts every drop from the rolls as we would on site, and gives you the order with a spare, the cutting plan, and the primer, lining and paste to go with it. It gives a quantity to order, not a set-out, and never a price.

1 The wallpaper

Not sure? Leave the standard roll and free match: the result says what it assumed.

Type the width and length as they are printed, in centimetres or inches, metres, feet or yards.

There is no pattern to line up across the joins. Each length can start independently.

2 The wall or the room
What you are measuring
Measured in

Height to paper: from the top of the skirting to where the paper stops, at the ceiling, the cornice or the picture rail. A room is counted as one run round its walls.

A stairwell, a sloping or curved wall, or a ceiling? We measure those for you: send us your measurements.

3Doors, windows, chimney breasts and the walls' condition (optional)Takes out drops over doors and windows; sets the primer and lining.

Doors, windows and niches

Chimney breast and alcove returns

Each side of a chimney breast or an alcove is a return. Its depth is added to the width of the wall.

Anything else about the space?

How it counts

The method, with worked examples.

Why width decides the number of drops, how the pattern repeat changes the cut, why we count drops rather than add a percentage, and when doors and windows save a drop: our guide to how much wallpaper to order works through it by hand. The materials follow our preparation tables and the lining papers, pastes and primers we use.
