Finding your Ring Size:

  1. Find a piece of string or strip of paper no wider than 3/4".
  2. Wrap it around the base of the appropriate finger.
  3. Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.
  4. With a ruler, measure the length from the starting end of the string/paper to the pen mark.
  5. Use this measurement and the chart to the right to determine your ring size.
  6. Don't measure cold fingers, as this is when fingers are their smallest.
  7. For the most accurate reading, measure the finger at the end of the day when the finger is the largest.

If you're buying the ring as a surprise

  • Ask your partner's mother or a friend if they know the size.
  • Borrow one of your partner's rings and slide it down a tapered candle. Then measure it using the chart below
