Ring Sizing Guide
Find your size by measuring either a string you've wrapped around your finger or by using a ring that fits. Then, use the ring size charts below to find your size.
Measure Your Finger
Take a piece of non-stretchable string, ribbon, thread, or a thin strip of paper. Wrap it comfortably around your ring finger, close to the knuckle. With a pen, carefully mark the spot where the string overlaps. For accuracy, make the marks small. Unwrap your marked length. With a ruler, measure it in millimeters. Find your measurement below.
