Ring Size Chart

Follow these directions to measure your finger. They will give an approximate guide to establish your ring size. 

  • Find a piece of string or strip of paper no wider than 1.4 cm (1/2 inch).
  • Wrap it around the base of the appropriate finger.
  • Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.
  • With a ruler, measure the length from the starting end of the string/paper to the pen mark.
  • Use the chart below to determine your ring size.

Here are some tips to make your ring size measurement more accurate:

  • After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.
  • Don't measure cold fingers. This is when fingers are their smallest
  • For the most accurate reading, measure the finger at the end of the day when the finger is the largest
