Finding your ring size

To determine your ring size, do the following:

  • Use a piece of string or dental floss and wrap it around the base of your finger.
  • Use a pen to mark the point on the string where the end meets.
  • Use a millimetre ruler to measure the string.
  • Choose the closest measurement to the chart below to find your ring size. If you fall between two sizes choose the larger one. 

Tips for best results:

  • Allow enough room to accommodate your knuckle.
  • Keep in mind, different fingers on the same and the opposite hand may have different sizes. Therefore, 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.
