Girls typically stop growing by the age of 14 or 15. Girls may reach their adult height earlier or later depending on the time puberty begins. Puberty includes the development of sexual attributes and other physical changes children go through, which includes an increase in both height and weight.
The first characteristic of puberty in girls is the development of breasts and visibly rounded hips. Pubic hair grows at least six to 12 months following breast development. An increase in growth typically begins at this point, with height reaching its peak approximately two years after puberty begins. On average, a girl's growth reaches its peak at the age of 12. Menstruation typically begins after the peak in growth at 12 ½ years of age.
True puberty typically begins between the ages of nine and 14. Studies show that the start of puberty corresponds with improved nutrition and the amount of body fat a child has. Girls that live in societies with better nutrition begin puberty earlier, while girls that are lean and muscular typically begin puberty later. One consequence of early puberty is a decrease in height as an adult. Puberty that begins earlier also ends earlier, which provides fewer years for girls to grow.
