Ring Size Guide
How to Measure the Inside Diameter
If you have a ring that already fits you well:
- Place the ring flat on a ruler.
- Measure the distance straight across the inside of the ring (from one inner edge to the opposite inner edge).
- This measurement (in millimeters) is the inside diameter of your ring.
- Match this number with the chart to find your ring size.
