Find Your Ring Size
A perfect fit matters. Here are three reliable ways to find yours.
Measure an Existing Ring
Place a ring that fits your intended finger on a ruler. Measure the inside diameter in millimeters, then match it to the size chart below.
Use a Strip of Paper
Wrap a thin strip of paper snugly around the base of your finger. Mark where the paper overlaps, then measure the length in millimeters. This is your inner circumference — find it in the chart below.
Visit a Local Jeweler
For the most accurate measurement, visit any jeweler and ask to be sized with a ring mandrel. This is quick, free, and eliminates guesswork.
