I want to increase my height is it possible? i am 16

Maybe: Eventual height is largely based on genetic & health factors.If you are healthy,get proper rest & exercise you should reach your destined height.Females finish growing taller ~16 & males 17-18. An x-ray of your wrist/hand could show if your growth centers are open to more growth & for how long, if they have closed you are done.You cannot add inches through special diet/stretches/exercise/supplems

It depends...: This depends on many things, your sex and stage of puberty completion are the important factors. If you are a girl who started her period at say 14, two years ago, then you have completed your adult height. If you are a boy who is just starting puberty, you may well have more growing to do. Your final adult height is largely related to your genetics! Hope this helps!
