Ring Size Guide
How Do I Measure My Finger for a Ring?
Take a piece of string, ribbon, thread, or a thin strip of paper and wrap it around your finger, close to the knuckle.
With a pen, carefully mark the spot where the string overlaps with its end and either hold it up to a ruler that has millimeter measurements, or to the graphic below.
Use the chart to determine your ring size.
