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.
