Measure an existing ring

  1. Select a ring that fits the finger comfortably.
  2. Measure the inside diameter of the ring in millimeters (mm).
  3. Compare your measurement to the chart above to find the corresponding size.

Measure your finger

1. Use a flexible measuring tape or a piece of string and wrap it around the finger where you plan to wear the ring. If it’s part of a stack, consider the exact position on your finger. If using string, mark the point where the ends meet.

2. Lay the string flat on a surface and measure the length up to the mark using a ruler.

3. Compare your measurement with the size chart to find your size. If your measurement falls between two sizes, choose the larger one for a more comfortable fit.
