Ring Size Guide

We use standard U.S. ring sizes, from 4 to 12. Use the table to convert from a European size, or measure at home in two minutes.

Measure at home

1. Cut a thin strip of paper, about 5 mm wide.
2. Wrap it snugly around the base of the finger you'll wear the ring on.
3. Mark the spot where the paper overlaps.
4. Lay it flat and measure the length in millimeters — that's your circumference. Find it in the table.

Three quick tips

• Measure at the end of the day, when fingers are slightly larger.
• Between two sizes? Go up half a size for wide bands, down for thin ones.
• Have a ring that already fits? Measure its inside diameter and compare with the table.
