Ring Size Guide
Do you have an existing ring to measure?
Follow these steps to measure the inside diameter of a ring you already own:
1. Pick a ring that fits the desired finger well, preferably a signet ring.
2. Measure the inner diameter of the ring in mm/inches.
3. Use the chart below to find your ring size. If the ring falls between two sizes, order the larger size.
