How can i grow taller? my dad is 5"8 but i am only 5"5

You still have: About another three years to grow. Your stature is written into your genes.

Hard to say: Future growth is dependent on whether the growth centers in your long bones remain open. Most have closed in 18 yo males. If your family has a history of delayed growth, these may be open and growth possible.An x-ray of your wrist and hand can detect your bone maturity.If the index is consistent with 18, you are done, if 14 you can grow more.
