Overview
Size Guide
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.
