I am 5ft8 and a male and I turned 16 in September.What will most likely be my final height?

If any of your family member related to your parents, let's say your grandparents, are pretty tall as well, you could say you can still grow taller until you're 21 years old. Height is also related to genes and pretty much what your lifestyle is, if you plan to grow taller, it's best you take more calcium and exercise more, sports such as basketball, rope jumping and etc will increase your height scientifically. You can't really tell how much you will grow cause genes are one of the factors too. So stay tune and see what might happen xD

Your height is determined by your genes that you get from your parents. For most boys, growth hormones are still very active during puberty and slows down at 20-22 years old. So, you will still be growing.

However can exercise promote height growth beyond genetic limits?

In brief: No. But living a healthy life in general helps you reach your maximal height (which is already predetermined by your genetics). Although, adequate sleep, good nutrition, exercise, stress reduction helps you achieve that faster.

Impossible to say, I've know kids that at 16 were 5 foot 4 and ended up 6ft plus by the time they hit 19.

Dang chill son. I'm 5'8 and I turned 17 in September. Let me break it down for you chill out and enjoy. Stop worrying I'm 17 and i hardly have any facial hair and as I do have chest hair and got it when I was 15 don't expect this stuff until your 18

I'm also 16, and am 5.9 and 1/2. My doctor said that I will have another growth spurt or two. I'll be done growing by about 20-21. Your not done yet! I have had pubic hair since about 5-6th grade. I've got armpit hair and aa little mustache. Hair, takes a little longer.

Most chest hair will come in in the late teens and early 20s. Height wise most guys are within about 2 inches of their dad- plus or minus 2 inches compared to his height.

6 foot between the ages of 17-21

Most likely. It's not a bad compromise, though.

when your done growing at the age of 21 you'll be taller than all of them

You're probably done. I was at your age.
