What is the average breast size for a 14 year old? - Virtual Teen Forums
January 20, Location: What is the average breast size for a 14 year old? There isn't really an average breast size for girls who aren't fully developed, I don't think. You could get one, by asking a bunch of girls and averaging the sizes, but it wouldn't be very accurate because of the large range. Some girls are almost fully developed by 14, while others will barely have anything on their chests at all yet. So you could get an average, mathematically speaking, but it wouldn't tell you anything about how "normal" you are because girls develop at all sorts of different rates. I know that the average for a fully developed American woman is around 34C, but that's just the average.
