Measuring for your ring:

Option A: Circumference

  1. Wrap a piece of string or floss around your finger where you’d like your ring to be.
  2. Make sure that the string is pulled snug to your finger, to find your best fit.
  3. Mark the spot where the paper meets and measure the distance with a ruler in either inches or millimetres.
  4. Use the chart above to determine your ring size.
  5. If you are sitting in half size but looking at a ring with no half sizes, we recommend sizing up.

Option B: Diameter

  1. Select an existing ring that fits the desired finger.
  2. Measure as best as you can, the internal diameter of the ring in inches or mm.
  3. Use the chart above to determine your ring size.
  4. If you are sitting in half size but looking at a ring with no half sizes, we recommend sizing up.
