Height for girls at 13 years

At 13 years, the median height for girls on the CDC 2000 growth charts is 157.2 cm (61.9 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 152.5 and 161.8 cm, a spread of 9.3 cm. The outer lines of the chart, the 3rd and 97th percentiles, sit at 144.0 and 170.0 cm.

Since 12 years, the median has risen by 6.0 cm over 1 year. By 14 years it reaches 160.4 cm.

For boys at 13 years the median is 156.1 cm, 1.1 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 13 years who measures 160.0 cm is at about the 66th percentile, meaning that out of 100 girls this age, about 66 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.
