Size Guide

Find Your Ring Size

Three methods to find your perfect fit at home. When in doubt, go up half a size — Sara can always resize later.

A ring should slide over the knuckle with a little resistance and sit comfortably at the base of the finger. When in doubt, go up half a size.

Measure in the Evening

Fingers swell throughout the day. Evening measurements are the most accurate.

Between Sizes? Go Up

If you fall between two sizes, choose the larger one. It's easier to size down than up.

Measure 2–3 Times

Take multiple measurements on different days and average the results.
