Ring Size Chart

Not sure about ring sizes? Try this simple method to determine an accurate size:

  1. Cut a piece of string or a strip of paper (if you are using paper, it should be no wider than .25 inches). Wrap the string or paper strip around the base of your ring finger.
  2. Mark the string or paper where it overlaps to form a complete circle.
  3. Use a ruler to measure the length of the section of string or paper where it overlaps around the finger.
  4. Compare your measurement with the chart below to determine your ring size.

Note:

  • If your knuckle is significantly larger than the base of your finger, you should measure the knuckle as described above as well as the base of the finger and pick a size somewhere in between. This should give you a good idea of your ring size.
  • If your measurement is somewhere in between sizes, it’s generally better to round up to the larger size.
