Height : We need to know the height of your parents. Barring that have your doctor take an xray of your left wrist to see if you have. Any growth left.

Unlikely to happen: By 18 most males are at the end of their linear growth ; their growth centers are closing.An xray of the left wrist and hand can be arranged and will show if your growth centers stil l show more potential.If you entered puberty late and have a bone maturity more like a 15 yo you may get 2 inches.
