Ring Size Chart

To measure your ring size, use a piece of string or dental floss and wrap it around the base of the finger you intend to wear the ring on. Then take a pen to mark where the pieces of string meet. Next, use a ruler to measure the length of the string and choose the closest measurement to find your ring size.
