Most men stop growing taller at about age 16, according to KidsHealth.org. Even if they do not grow taller after that age, their muscles usually continue to develop.

The growth spurt for males starts at about age 11, versus age 9 or 10 for females, according to WebMD. Boys can grow up to 4 inches a year during the growth-spurt period. Males stop growing when puberty ends and their growth plates close, preventing additional growth. Even when a man's arms and legs are at their full length, the chest and shoulders continue to expand until about age 20, notes the BBC.
