It is very difficult or impossible to accurately predict someone's final height. This is because of the complex genetic process that is involved. To give your genes their best hope of making you taller, and to get healthier for the sake of getting healthier, do the following:-
[1] Get plenty of sleep.
[2] Get plenty of moderate exercise such as walking, swimming, yoga and tai chi.
[3] Eat only fresh food and a wide variety of it.
[4] Do not smoke, take drugs or drink alcohol.
[5] Do not fret over things that you probably cannot change.
[6] You could also ask your doctor to refer you to an endocrinologist (puberty doctor) but there would be little point in doing this if you are as tall as the rest of your family of the same age.
[7] Remember that the average height of all 25 year old men in the whole wide world, is 5'9".
