Boys continue growing until age 17 or 18. Boys and girls grow about two inches per year until they reach puberty. Then they each have a growth spurt that lasts a year or two. During the growth spurts, boys grow a little faster than girls. Girls reach puberty (on average) about a year before boys do. Girls also end puberty earlier than boys.
What You Can Expect During The Teen Growth Spurt. The teenage growth spurt varies by gender, with different timing of onset and rates of growth. Girls tend to experience their growth spurt earlier than boys, nearly two years earlier. The sexual maturation aspect is a big piece of the growth spurt. Girls become hippy, leggy and buxom, while boys boast more muscles and hair.
