Ring Sizes

 

Tips for finding your ring size:
  1. Measure your finger in warm temperatures at the end of the day.
  2. If your knuckle is a lot larger than the base of your finger, use Method B below, except measure both the base of your finger and your knuckle and select a size in between the two.

Tips if you’re buying the ring as a surprise:
  1. Ask your intended recipient’s mother or friend if they know his/her finger size.
  2. Borrow one of your intended recipient’s rings and use Method A below. (Make sure to borrow a ring that fits the finger you intend your gift ring to fit.)

Other tips and information:
  1. When considering a wide band, move up a size from your measurement, for comfort’s sake.
  2. Different countries have different ring-size systems. All sizes listed here are standard American sizes.
  3. The average woman’s ring size is about 6. The average man’s ring size is about 10.
  4. Your ring size will be about half a size larger on your primary hand (i.e., the hand you write with)
