Wall Mural Calculator

Enter your wall to get the mural size to order with room to trim, the number of strips it's printed in, or whether a ready-made picture is big enough.

The repeat and the match are on the roll label and the product page. Trim is the paper cut off at the ceiling and the skirting: Morris & Co allow 10 cm a drop, Brewster 4 in.

Photowall recommends 6–10 cm (2.5–4 in) extra on the width and the height for walls that aren't straight. Graham & Brown print made-to-measure murals in 50 cm (19.6 in) strips; check your maker's strip width.

Batch numbers. Rolls printed together share a batch number on the label; rolls from different batches can differ slightly in colour. Buy every roll at once, check the numbers match before you cut, and keep the label.

An estimate for planning. Sloping ceilings, stairwells and walls out of square take more paper: ask your decorator to check before you order.

Murals are ordered by the wall, not by the roll

A mural is one picture. Made-to-measure ones are printed at the size you ask for and cut into strips that go up side by side; off-the-shelf ones come at a set size on one or several panels. Either way there are no rolls to count: you order the wall plus a margin, then check both directions are covered.

In Mural mode the wallpaper calculator starts from a 4 × 2.5 m wall printed to measure. Adding Photowall’s 10 cm gives 4.1 × 2.6 m to order, which in Graham & Brown’s 50 cm widths means 9 strips. Switch Sold to Fixed size and enter a ready-made design’s dimensions and panel count: you’ll see whether it reaches with the margin, how much comes off each edge, and how wide each panel is.

Doors, windows and sloping ceilings

Take the full wall, openings and all. The picture is a rectangle that gets cut around the frames, so the scene continues above a door and below a sill. Under a slope, go by the highest point. Decide before you start which edge of the image you can spare, since that is where the trimming happens, and begin hanging from the side you want intact.
