Height for girls at 8 years
At 8 years, the median height for girls on the CDC 2000 growth charts is 127.6 cm (50.2 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 123.7 and 131.6 cm, a spread of 7.9 cm. The outer lines of the chart, the 3rd and 97th percentiles, sit at 117.1 and 139.1 cm.
Since 7 years, the median has risen by 6.1 cm over 1 year. By 9 years it reaches 132.9 cm.
For boys at 8 years the median is 127.9 cm, 0.3 cm more 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 8 years who measures 130.0 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.
