Generally upto which age can a man grow taller?

Usually 16-18: Linear growth can continue until the growth centers close, which corresponds to a bone maturity of 18 in males.In some, their growth centers close later, at a given age in the early 20's. An x-ray of the wrist and hand can be assessed for bone maturity and yield potential for growth.Once the centers close, no hormones, supplements or other tricks can add more height.
