Ring size guide
UK ring sizes run from A to Z. The most accurate way to know yours is to try a ring sizer in the shop, which is free and takes a minute. If you can't come in, this guide gets you close.
Find your size
- Wrap a strip of paper or a piece of string round the base of your finger, snug but not tight.
- Mark where it meets, then measure the length in millimetres.
- Enter it below, or find it in the chart.
Measure at the end of the day, when fingers are largest, and make sure the ring will pass over your knuckle. A wide band fits more snugly, so go up half a size for bands of 6mm or more.
