Height for boys at 2 years
At 2 years, the median height for boys on the CDC 2000 growth charts is 86.5 cm (34.0 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 84.1 and 88.8 cm, a spread of 4.7 cm. The outer lines of the chart, the 3rd and 97th percentiles, sit at 79.9 and 93.0 cm.
Since 23 months, the median has fallen by 0.5 cm in one month. By 3 years it reaches 95.0 cm.
For girls at 2 years the median is 85.0 cm, 1.5 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 2 years who measures 88.0 cm is at about the 67th percentile, meaning that out of 100 boys this age, about 67 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.
