How to Determine Ring Size

Diameter (mm)

  • Take a ring you or the person you are buying for already owns.
  • Measure the diameter, inside of the ring, from one side to the other. See image.
  • Use the Ring Sizing Chart to find your size.

Circumference (mm)

  • Wrap a strip of paper, or thin string, around your finger just above the knuckle. Mark the point at which the two ends meet.
  • Measure the paper or string from end to end to find the circumference.
  • Use the Ring Sizing Chart to find your size.

Please Note:

Some sizes may not be available in every style. We strive to have a wide variety of sizing for each ring, but it will depend on our wonderful suppliers.
