How to measure

The Hands-on Method

1. Grab a tape measure, length of string or strip of paper.
2. Wrap it around the finger you’ll wear your ring on—if you’re creating a ring stack, consider where on your finger the ring will sit—and mark the place where it joins.
3. Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark.
4. Match the length above using our size chart to find your correct ring size.

Measure an Existing Ring

1. Choose a ring that already fits your finger well.
2. Measure the interior diameter of the ring in millimeters (mm)
3. Use our measurement chart to match the size of your ring to the closest size in mm.
