Im 18 years old can i be taller or its done?

Growth: Your final height may not be reached until you are in your early 20's. An x-ray could be taken to see if your growth plates in your bones are closed.

Unlikely to happen: Some kids continue to grow taller into their late teens or rarely early twenties but only when their bone maturity lags behind their age. If the growth centers of the long bones have fused, you cannot grow taller. A single x-ray of the wrist ; hand can yield a bone maturity. When you have reached bony maturity, you are done.
