What is a repeat pattern?
Most of the fabrics and wallpapers you see with a pattern on them will have been designed as a repeat pattern.
Repeat patterns enable the manufacturer of the fabric or the wallpaper to print an even, duplicate design across the whole surface without showing any gaps or joins. Usually you won’t know the pattern comes from one tile or image that is then run again and again across the paper or fabric, it’s quite fun to try to find the repeat in design, it’s sometimes very hard.
How to measure a repeat pattern..
Often if you’re working with an interior designer, having curtains made up or a sofa re-upholstered, the curtain maker or upholsterer will ask you the measurements of the repeat pattern, so they can work out how much fabric to buy.
This is because they will want to match the pattern across the seams and need to know how much fabric or wallpaper they will have to sacrifice to match this pattern. If the pattern is a small repeating dot, then the fabric or paper will only need to be lined up by a few cm, but if the pattern is a large floral or botanical design, then they may have to sacrifice 50cm of the wallpaper or fabric to line the images up across the join until they matches. This will mean having to buy more fabric to accommodate the bits you cut off to line up the print.
Below are two different scales of the same Nettle design. The one with the stripe is a smaller repeat, so will need a bit less fabric when making up. Can you see the difference in the scale of the print?
Measuring a repeat
Most fabric or wallpaper suppliers will be able to tell you what the repeat pattern measurements are if you ask. However, if this is not the case, or if you’ve inherited a piece of fabric and you’d like to work it out yourself, it’s very easy if you follow these steps:
Lay the fabric or wallpaper out on flat surface like a table.
Look carefully at the design and try to find an image or detail that is easy to spot, like a bird or a flower.
When you’ve found an image that you can find again, look for the next exact duplicate of that detail above the one you’ve chosen. Not one that looks similar but exactly that detail, this bit is important.
When you’ve found exactly that detail again above or below, measure the distance between those two points vertically. That is your vertical repeat.
Then find a detail in the design that you can find again, and measure the distance horizontally between those two points or images. That is your horizontal repeat measurement.
Now write down the vertical and horizontal measurements, this is the size of your repeat pattern.
In the images below of my Wren design I’ve added a green square around the repeat pattern tile. Can you see the white and orange flower that’s turned away from us at the top and the bottom of the square? That’s what I’ve used as my guide for the vertical repeat. Then there’s a white flower with blue stamens, next to the bird, that’s what I’ve used to measure my horizontal repeat. Those two measurements, the vertical and the horizontal, give you the size and dimensions of your pattern repeat.
Here are some repeat patterns by the masters of fabric design, from the Arts and Crafts Movement at the turn of the last century, William Morris and Charles F A Voysey. Can you spot the repeat pattern in their designs?
