Using string, ribbon or thread, cut a length long enough to wrap all the way around the finger you want to measure.
Wrap the string, ribbon or thread around your finger in a circle. Secure with tape or by tying. Make sure the secured string ring can slip over your knuckle without simply falling off.
Using a chart from a company, such as Jared or Zales, compare the ring you created out of string to the circles on the chart to determine ring size. The string ring should perfectly match the circle on the size chart for the best fit.
