Dr. Wang Liyan
A 9-year-old boy’s normal height ranges approximately from 124 cm to 146 cm, and his weight typically falls between 22 kg and 44 kg. However, individual variations exist. A child’s height is partly determined by genetics, while environmental factors (e.g., nutrition, physical activity) contribute about 30%. If a child’s height is below average, increasing calcium intake may help. Appropriate outdoor exercise—such as rope jumping, basketball, and swimming—can also support healthy bone development and promote height growth.
