How tall may I be and what can I do to help height growth?

Im 16 and 5"8 1/2 which I know is bang smack average for a teenage boy in the UK, yet I still feel short as my dad is 6"0 and was a fast grower in his teenage years, aswell as my mum who is 5"10 which is tall for a woman. The women In my family range from 5"7 to 5"11, my sister being one of the tallest at 5"11 (she is 20) and the men range 5"11 to 6"4 the average being 6"1 1/2 for the men. They all say how they were fast growers though, I have inherited the stocky strong build of my family yet Im feel short in my family being only 5"8 1/2 at 16, what can I do or how much taller will i get?
