How to use this guide

Place one of your rings, that can be worn comfortably (but still has slight resistance), on the circles shown in your Ring Size Guide document.

Find the circle that matches closest to the inside edge of your ring. If your size falls between two circles, choose the larger size. The measurement shown below each circle is the inside diameter of your ring.
