Average height for a 16-year-old boy
At exactly 16 years old, the median boy in the US is 5'8½" (173.5 cm) tall, according to the CDC growth charts. Half of 16-year-old boys are between 5'6½" and 5'10½", and about 9 in 10 fall between 5'3" and 6'1".

| 90th | 6'0" | 182.8 | 72.0 |

What’s typical at 16 for boys
Between 16 and 17, the median boy grows about ½ in (1.8 cm) — from 5'8½" to 5'9".
A median 16-year-old boy has reached about 98% of the CDC's median adult height for men (5'9½"), so roughly 1½ in (3.3 cm) of growth is still typical from here.
Most boys are past the fastest part of the growth spurt and growth is slowing, though late bloomers can still add several inches. Growth in height typically finishes between 16 and 18.
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.
How tall will a 16-year-old boy be as an adult?
Height at 16 is one input. The calculator combines it with both parents’ heights and puberty timing to give the range adult height will most likely land in — free, no account.
