5"1 - same height as my mum, dad's 5"5 and my brother is 4"8. I have a very small family! I was average until I was about 11 or 12 and then my growing slowed down/stopped!
You'll change your mind at some point for whatever crazy reason, women always do. My sister was the same way. Im just glad there is zero chance for me to go through that! Lol
