At 15 years old and 1.6 meters tall, how much more can one grow?

Generally, a 15-year-old who is 1.6 meters tall may still grow another 3–5 cm, but the exact amount varies depending on individual circumstances and cannot be generalized.

At age 15, individuals are typically in puberty, which is the optimal stage for physical growth and development. If one maintains a balanced diet, engages in regular physical activity, and still has open growth plates (as is common among most adolescents), growth has likely not yet ceased, and height may increase by approximately 3–5 cm—or even 8–10 cm. However, the actual amount of growth depends on individual physiological factors and cannot be universally determined. On the other hand, if precocious puberty occurs—such as boys developing before age 9 or girls before age 8—the increased secretion of sex hormones and steroids may cause the growth plates to close by age 15, potentially halting further growth and limiting final height.

It is recommended to engage in regular physical activities such as volleyball, gymnastics, and jump rope, which can promote the development of bones, muscles, and ligaments in the body, thereby supporting increased height to some extent.
