How big are 13 year old's boobs?

[Eddie22]

I am 13 and kinda new to the who sex thing. I like this girl in my class (i think she is really sexy), and it looks like she has small to medium sized boobs. She is also 13. I just learned that some girls in middle school wear support bras to make there boobs look bigger. How big are her boobs? Are they larger than adverage, or just normal. How big are the adverage 13 year old girl's boobs?
