Men Ring Size Chart
How to measure
Wrap string around the base of your partner's finger (where a ring would typically sit) and use the marker to note on the string where the two ends meet. Unwrap the string, and use a ruler to measure the distance between the two marks. You can then use this measurement to find the ring size on a chart.
