you could be 6,2 both my parents are 5.10 and im 6.6. i think the most you can grow past your mother is 10 inches. i have a cousin who has parents that are 5.5 and hes 6 foot.
i guess it depends on what matters to you in your life. you can make it your mission to be as tall as you can. its possible . my cus was obsessed he wanted to be as tall as me. so he did stretching and took a ship load of vitamins. he was real little at 12 years old tho. he was like 4,10 .
but i knew this guy from school that grew like 5 inches after high school. its really a mystery to me.
