How to Measure Your Ring Size with a String

  1. Cut a piece of string or floss and wrap it snugly around the base of your finger, just below the knuckle. Make sure it’s not too tight, as you want the ring to be comfortable.
  2. Mark where the string overlaps with a pen or marker.
  3. Lay the string flat and measure its length in millimeters with a ruler.
  4. Compare the measurement to the ring size chart above to determine your size.

For the most accurate fit, measure your finger at the end of the day when it’s at its largest, and avoid measuring when your hands are cold.
