Ring Sizing
Wrap a piece of string or paper around the base of your finger. Mark the point where the ends meet with a pen. Measure the string or paper with a ruler (mm) then divide by 3.14 (or Pi) to get the diameter of the ring. Pick the closest measurement on the ring size chart to find your ring size.
Use the chart below to determine your ring size.
