Ring Size Guide

How to work out your ring size

We recommend you get your measurments at your local jewellers. However you could estimate your ring size at home by following these instructions. Measure your finger at normal temperature, do not measure when your hands are very hot or very cold.

1. Wrap a piece of string or strip of paper around your finger. Cut where the two ends meet.

2. Measure the length of string or strip of paper to the nearest mm. This gives you the circumference of the ring.

3. Use the table below to convert the length in mm into a UK ring size.
