Ring sizes - CHART

How to define a ring size?

1. Measure the diameter of any other ring that fits a given finger. Read out the ring size that matches the diameter.

2.Measure a finger’s circumference. Read out the size matching the circumference.

Please remember that ring sizes are measured up to 1/10 of millimeter. So the difference between two adjacent sizes might be so small that insignificant and be in the measurement – ballpark.
