Question: what is the average ring size for a woman's ring finger?
Answer: The average woman's ring finger is a size 6, for a ring that is about 2-3mm wide. When you go to a jewelry store, most women's rings in the case are either 6 or 6.5, and the bands are all about 2-3mm wide with a few exceptions. The vast majority of engagement rings will be in the range of 5.5 - 6.5.
