Height for girls at 12 years

At 12 years, the median height for girls on the CDC 2000 growth charts is 151.2 cm (59.5 in): half of girls this age measure less and half more. The middle half of girls, from the 25th to the 75th percentile, falls between 146.2 and 156.1 cm, a spread of 9.9 cm. The outer lines of the chart, the 3rd and 97th percentiles, sit at 137.1 and 164.9 cm.

Since 11 years, the median has risen by 7.2 cm over 1 year. By 13 years it reaches 157.2 cm.

For boys at 12 years the median is 149.1 cm, 2.1 cm less than for girls, 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 girl at 12 years who measures 154.0 cm is at about the 65th percentile, meaning that out of 100 girls 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.
