Ring Size Guide

Measuring your ring size 

  1. Wrap string or paper around the base of your finger.
  2. Mark the point where the ends meet with a pen.
  3. Measure the string or paper with a ruler (mm).
  4. Pick the closest measurement on the ring size chart below to find your ring size.

Consider your knuckle. With a little hand cream applied to the finger, choose a ring size that feels slightly tight over the knuckle.
