How to measure:

  • Cut a string that is about 6 inches long.
  • Fold the string around the base of the finger, just below the knuckle.
  • Mark where the string ends with the pen.
  • Place the measured string on the ruler with the area marked on your right.
  • The number closest to the pen mark is the circumference of the ring in millimeters.
  • Use the ring size chart above to translate the measurements into a ring size.
