The Hands-On Method

  1. Take a strip of paper, string, or flexible measuring tape.
  2. Wrap it around the finger you wish to wear your ring on.
  3. Mark the point where the ends overlap.
  4. Lay it flat and measure the length in millimetres (mm).
  5. Match your measurement with the ring size chart above.

Measure an Existing Ring

  • Choose a ring that fits comfortably on the desired finger.
  • Measure the inside diameter of the ring in millimetres (mm).
  • Compare the measurement to the size chart above to determine your correct size.

Helpful Tips

  • Measure your finger at the end of the day when it is at its natural size.
  • Avoid measuring cold fingers, as they can be smaller than usual.
  • If you are between sizes, we recommend choosing the larger size for a more comfortable fit.
  • Wider bands generally fit more snugly than slimmer styles.
