Rings Chart

To measure your finger circumference:

  • Wrap a thin strip of paper around your finger where you’d like your ring to be.
  • To find your best fit, make sure that the paper is pulled snugly around your finger.
  • Mark the spot where the two ends of the paper meet and measure the distance with a ruler in millimeters.
  • Use the chart below to determine your ring size.

To measure the diameter of a ring:

  • Using a ring you already own that fits well, measure the inside diameter of the ring with a ruler in millimeters
  • Note down the measurement and match it to the chart below.
  • If your size falls in-between two sizes we suggest buying the larger size.
  • If you are still unsure about your ring size and you would like further assistance, please contact us.
