Where growth stands at 13
These are the peak growth years for many boys, often 7 to 10 cm (3 to 4 in) in the fastest year. Early and late developers can look very different.
The average boy at 13 has reached 88% of the average adult man's height in the same charts (5′9½″). A boy who starts puberty late will be below average now and often catches up later; an early developer may be tall now and finish close to average.
Is my child's height normal?
Doctors look less at one measurement than at the pattern: a child who stays near the same percentile year after year is growing normally, whatever that percentile is. Talk to your doctor if your child drops across percentile lines, grows much slower than classmates, or is far below what both parents' heights predict.
