Helpful Tips

To measure your ring size, do the following:

  • Use a piece of string or dental floss and wrap it around the base of your finger. Do not make it too tight, just comfortable.

  • Use a pen to mark the point on the string where the end meets.

  • Use a millimeter ruler to measure the string.

  • Choose the closest measurement to the chart above to find your ring size.


Tips for best results:

  • Allow enough room to accommodate your knuckle.

  • Bear in mind, different fingers on the same and the opposite hand may have different sizes so measure the specific finger on which you are planning to wear the ring.

  • Measure your finger at the end of the day when your finger is likely to be largest.
