Answer

To estimate full adult height when you know a child's current height and what percentage of their final height it represents, use this formula: Full Height = (Current Height ÷ Percentage) × 100. For example, if a 9-year-old boy is 120 cm tall and this represents 75% of his full height, the calculation would be: (120 ÷ 75) × 100 = 160 cm. This means the boy will likely reach approximately 160 cm at the end of his growth period. However, this is an estimate, as actual growth depends on multiple factors including genetics, nutrition, overall health, and hormonal balance. Growth typically continues until the late teens or early twenties when growth plates in bones close.
