Girls generally do not stop growing immediately when they get their first period. Instead, most girls continue to grow for about 2 to 2.5 years after their first menstrual period. During this time, they typically grow an additional 1 to 2 inches (around 6 to 8 centimeters) before reaching their adult height. Most girls reach their final adult height around the age of 14 or 15, although the exact timing can vary depending on individual factors like when they started menstruating and their overall physical development. Early menstruation is usually followed by a larger growth spurt afterward compared to later menstruation. Therefore, getting their period signals that girls are nearing their adult height but have not yet completely stopped growing.
