What’s typical at 14 for boys
Between 14 and 15, the median boy grows about 2½ in (6.1 cm) — from 5'4½" to 5'7".
A median 14-year-old boy has reached about 93% of the CDC's median adult height for men (5'9½"), so roughly 5 in (13.0 cm) of growth is still typical from here.
This is the age with the widest spread: some boys are mid-spurt, growing 3–4 inches (8–10 cm) in a year, while others haven't started. The fastest growth comes around 13 to 14 on average. A boy who hasn't started yet isn't behind — he has more growth ahead of him than the ones who have.
How to read a percentile
A percentile compares a child with others of the same age and sex on the CDC 2000 growth charts — the same L, M and S values a pediatrician’s chart is drawn from, and where every number on this page comes from. The 50th percentile is the median: half of boys that age are shorter and half are taller. The 5th and 95th bracket the middle 90%.
Pediatricians care less about the number than the line. A child who stays near the same percentile year after year is growing normally, whatever that percentile is — a steady 15th is healthier than a 60th that has just dropped from the 90th. Crossing two of the major lines, or sitting below the 3rd, is the usual cue to have a pediatrician take a look. None of this is medical advice.
