My height prediction

[randomperson15]

I am 15.5 years old boy, weighting in at around 62 kg and I have a height of 179.1cm (182 cm with shoes). My mother said I have been in the 90th percentile as a baby and my sister is in the 95th percentile. However, my mom and dad are 163 cm and 175 cm respectively. My mom's father is 181 cm and my dad's grandfather was 193 cm. They didn't reach their potential height, mostly because of a vegetarian diet they used to have.

This is my current growth since 12 years old:

12 years: 163 cm

13.5 years : 170 cm

14.5 years : 174.5 cm

15.5 years: 179.1 cm

I also have some height measurements from when I was small:

1 years: 80 cm

3 years: 100 cm

5 years: 116 cm

What will be my height as an adult if you can give me a range?

The external conditions affect a lot of the growth as well so of course, it is not one hundred percent based on your genetics. Like @auntiejessi said, there is one calculation based on your parent's height but if you do some streching, sleep regularly and have a healthy diet, you have a potential to grow up to 185 cm.

There's no way to determine exactly how tall someone will be. There are some theories, but no exact science.

There's one that takes into account the parents' height, but your parents' heights were affected by diet, so that might not be accurate. We'll skip that one.

Another one is to double a boy's height at age 2. You don't list yours, but if we just go with 90 cm, since it's between your height at 1 and 3, you'd be 180 cm, which is close to what you are now.

However, you are 15 years old. There's no way to know what will happen. You could hit a growth spurt in 6 months or a year and gain another 10 or 15 cm. Or not. Next time you see your doctor, you could ask. They have ways of guessing, too, but it's also a guess.

I see. Using your method, it's 180 cm. I am assuming since I am still in the middle of adolescence, I should have time to surpass that. Do you think I have the potential of being over 6'?

[auntiejessi]

Well, one of your grandfathers is, so sure.

Genetics are mysterious. I have 2 nephews who are 17 and just keep growing and are 6", and will probably be taller than most of us. Meanwhile, their younger sister is just as petite as can be at 15, barely 5"2. Her doctor told her she's stopped growing.

Most boys stop growing by about 17 or 18, but I've seen some "late bloomers" who grow a bit after.

If you don't grow much more, though, that's okay. Is there a particular reason you're so concerned about it?

[randomperson15]

Not really, just for my own curiosity. I am only concerned that my percentile dropped and that I have been the same weight for a year.

My son is your age, and we have a lively curiosity in the family about whether he's coming to his full height or not. One can't tell by formulas using parents' heights (my parents have five daughters, and two of us are taller than the average female and one is much shorter). The doctor had my son's records in front of her once and said he would get to the height he is today, which happens to be about your height, but this summer he seems to be growing. A friend's brother even had a big growth spurt in college! So you really can't tell. Stand straight and stay slender and everyone will think you are taller than you are, no matter how tall that is. :-)
