international ring size guide

1. Wrap a strip of paper, string, or ribbon around the base of your finger, ensuring a snug fit.

2. Use a pen to mark the point where the ends overlap.

3. Measure the marked length (in millimeters) to find the circumference of your finger. 

4. Refer to the size guide below to find the corresponding ring size.

Measure your finger 3–5 times throughout the day at different times to get an average size. If you’re between two sizes, choose the larger one.

 You can also measure an existing ring from your collection. 

Use a ruler or caliper to determine the inner diameter.
