Question

hi im a girl but i wanted to know if a 15 year old male is 5'5 feet tall and i know guys stop growing when they r like 21, how tall do u think he will be by the age of 17 ,thank u bye

Answer 1

It's mostly genetics!  Take a look at his parents and grandparents.  If they're all tall, chances are he will be as well.  My son was 5'4 in grade 8 and by the time he got to grade 11 he was 6'2!  I'm 5'8 and his father was 6'2".  His sister is 5'11.  Everyone on both sides of the family is between 5'10 and 6'5"

Answer 2

It really all depends.  There are many factors that come into play like how much he eats, how tall his parents are, his other dna genes etc.
