How to Measure Your Ring Size
Wrap a thin strip of paper or a piece of string snugly around the base of your finger. Mark where the ends meet, then measure the length in millimetres against a ruler. Match this measurement to the circumference column above.
For the most accurate result, measure your finger at the end of the day when it is at its largest, and avoid measuring when your hands are cold. If your knuckle is noticeably larger than the base of your finger, measure both and select a size that sits comfortably between the two.
