What is the normal height for a 12-year-old boy?

For 12-year-old boys, the normal height range is generally between 145 cm and 160 cm. The relatively wide range is due to various factors including individual differences, genetic factors, nutritional status, physical activity, and sleep quality. As long as a child's height falls within this normal range, parents need not be overly concerned. However, if a child's height is significantly below or above the normal range, it is recommended that parents promptly take the child to the hospital for evaluation to rule out potential growth issues or medical conditions.
