I don't know if there is really a way to know just how tall you might be. I am 5'6 and have a cousin who is 6'11 (and that's not a typo,he really is almost 7 feet tall). Height runs in my family on both sides and some of us are way short, while some are very tall. My little brother didn't hit a growth spurt until he was 16 and he grew over a foot and a half, so ya never know. Think positively lol. Hope this helps.
