I 12 and I 5'2, my ma is 5'6 and my dad was 5'8, my sister is 5'2, bro is 6', will I get any taller?

There really isnt an exact way to know, but conisdering how tall your family is, and the fact that your only 12... i would say YES, you will get taller. Females grow till theyre about 20 or so anyway. Im 18 and im only 5'2.. so your 6 years younger than me, just now going through body changes ect. im sure you will grow! My guess is between 5'4-5'6 becasue thats average height for women. Dont stress about it though, just be happy being who already are! :) That is truly the best advice i can give you.
