Ring Size Guide

A perfectly fitting ring should be comfortable and secure, never at risk of slipping off. While the most accurate ring sizing is done in-store by professionals, you can also measure at home.

  1. Cut strip of paper or string.
  2. Wrap the paper or string around your finger and mark the point where they overlap.
  3. Measure the length of the string or paper with a ruler.
  4. Based on your results, select your size from the table below.
