Height for boys at 15 years

At 15 years, the median height for boys on the CDC 2000 growth charts is 169.9 cm (66.9 in): half of boys this age measure less and half more. The middle half of boys, from the 25th to the 75th percentile, falls between 164.6 and 175.1 cm, a spread of 10.6 cm. The outer lines of the chart, the 3rd and 97th percentiles, sit at 154.4 and 184.0 cm.

Since 14 years, the median has risen by 6.1 cm over 1 year. By 16 years it reaches 173.5 cm.

For girls at 15 years the median is 161.9 cm, 8.1 cm less than for boys, which is why the charts are drawn separately by sex.

From 2 years CDC recommends its own 2000 growth charts, which draw the 3rd to the 97th percentile; under 2, the WHO charts draw the 2nd to the 98th.

Reading the table: a boy at 15 years who measures 173.0 cm is at about the 65th percentile, meaning that out of 100 boys this age, about 65 measure less. From 2 years this is height measured standing. If a child of 2 or older was measured lying down, CDC subtracts 0.8 cm before comparing.
