How much taller can a girl grow after her first menstrual period?

Menstruation is an important indicator of the maturation of a female’s reproductive function. Girls typically experience menarche (their first menstrual period) around age 13, although some girls begin menstruating earlier—sometimes as young as age 10. Upon noticing their daughter’s first period, many parents naturally wonder whether she will continue to grow taller afterward. So, how much taller can a girl grow after her first period? Below, we address this question.

How Much Taller Can a Girl Grow After Menarche?

After menarche, girls generally grow approximately 4–5 cm per year until their epiphyseal growth plates (also called “growth plates” or “epiphyseal lines”) fully close, at which point linear growth ceases. Although menarche often occurs around age 10–13, growth continues afterward—albeit at a slower pace—until epiphyseal closure is complete. During puberty, girls should maintain a varied and balanced diet, avoiding picky or selective eating habits. They should consume ample high-protein foods—such as eggs, large shrimp, pork ribs, and fish—and ensure adequate calcium intake. Rapid physical development during puberty, coupled with incomplete establishment of endocrine regulation following menarche, may predispose adolescent girls to menstrual irregularities.

Knowledge Extension: Important Considerations During Menstruation

1. Maintain Warmth

Regardless of season, girls should take care to keep their bodies warm during menstruation—especially the abdominal area—to prevent menstrual cramps or blood clot formation caused by cold exposure. Avoid bathing with cold water, walking barefoot on cold floors, or sleeping directly on the floor. Hair should be thoroughly dried after washing to reduce the risk of catching a cold.

2. Maintain Hygiene

During the first menstrual period, special attention must be paid to personal hygiene. Showers—not tub baths or sitz baths—are recommended to minimize the risk of vaginal infection. Additionally, girls should keep the external genital area clean by frequently changing sanitary pads and undergarments, thereby preventing bacterial overgrowth and associated gynecological issues.
