Ring Size Guide

If you don't know what ring size you are it is very easy to find out. Follow these steps:
  1. Wrap a piece of string around your finger.
  2. Mark the point where the two ends meet.
  3. Repeat a few times for accuracy.
  4. Measure the string against a ruler to get the circumference of your finger in millimetres.
  5. Use the chart below to convert the millimetre dimension.

Note: Always take into account your knuckle size.
