How to Measure
You need a string or a strip of paper and a ruler with millimeters.

Wrap a string or strip of paper around the base of your finger.
- 2
Mark the point where the string overlaps itself.
- 3
Measure the length in millimeters — that’s your circumference. Match it below.

Between sizes? Size up for a comfortable fit. Still unsure — measure again at the end of the day and go with the larger size.
Have a ring that fits? Measure its inside diameter, edge to edge, in millimeters, and match it to the Diameter column.
Each ring’s page lists the sizes it comes in.
