LoL, you're so silly Ithoray.. If you haven't really hit puberty super hard yet, then, you're going to eat your words pretty soon
Anyway, I was just a tiny bit over 5" when I was 13.. Now I'm a bit over 6"(maybe 6.3 or so) and I'm going to be 15 pretty soon.
So I'd say you're about normal. Your one-eyed champ probably isn't completely done growing yet anyway.. Most 13 year old's aren't.
Hope I helped..
You'll probably be in the range of 5.5-7" as an adult~
