I am almost 17 but i have basically stayed the same height since i was 14 and i am only 5'9". my dad is 5'11". can i still grow to that?

Growth: it all depends on if your growth plates are closed or not. If they are not closed you can still grow. Go see your doctor and have him take X-rays to see. I must say I am jealous as I am only 5' 6". However, great things come in small packages. Good luck.

Unlikely: Both parents contribute equally to expected final height.In males that is equal to the average of both parents plus 2-3 inches. If you have not grown any in 3 years it is unlikely you will grow taller. An x-ray of your wrist/hand can detect open/closed growth centers. If open=more growth, if closed, you are done.
