If i am a boy , i can grow height until when years?

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.
