Pattern

Starting pattern: Morris & Co Strawberry Thief, 61 cm repeat, straight match

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.

Morris & Co’s rolls and rules

From this page the wallpaper calculator starts on the standard Morris roll with Strawberry Thief, which the firm lists at 61 cm vertical repeat and straight match, plus the 10 cm allowance its own tool adds per length. Change it to your design; each one’s details give width, repeat and match.

Morris & Co’s calculator asks for the widths of all walls added together and assumes leftover part-widths find a use. Here the strips are counted round the room the same way, and the short bits over doors and windows are then fitted into the ends of rolls, rather than nothing being taken off at all.

Big repeats and wide widths

Plenty of Morris designs have long repeats. On a 2.4 m wall Strawberry Thief’s 61 cm makes every length 3.05 m, still three per roll, with little to spare. Enter 2.7 m and the length stays 3.05 m; from 2.96 m upwards it becomes 3.66 m and a roll holds two. The wide Strawberry Thief, 68.6 cm across with a 42 cm repeat, covers the same room in fewer widths: the table sets both side by side. Pick the wide-width size in the roll menu to try any of the broader Morris designs in your own room.
