Where growth stands at 12
Many girls are at or just past their fastest growth, and first periods often start around now.
The average girl at 12 has reached 93% of the average adult woman's height in the same charts (5′4½″). A girl 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.
