Ring Size Guide

We have included a table of international ring sizes to make it easier for you to choose the right ring size. You can use a ribbon of paper to measure the diameter of your finger by wrapping it around your finger and measuring the length where the ribbon meets. The table below shows millimeters (mm) and inches (in) for your ease of reference.
