Growth in the year after 7 years

The median rises 3.1 cm in the next 6 months and 6.0 cm in the next 12, reaching 127.8 cm at 8 years.

This is the slowest stretch of the girls' table between ages 4 and 10: the smallest 12-month gain, 5.0 cm, starts at 8 years 6 months. After that the median speeds up again, to 7.3 cm in the 12 months from 11 years 1 month.

The site's guides use growth under about 4 cm a year, between age 4 and puberty, as a reason to ask a pediatrician. In this table even the lowest line, the 3rd percentile, goes up 5.4 cm over the next 12 months.

Spread at 7 years

The 3rd-to-97th range covers 20.8 cm and the 25th-to-75th range 7.5 cm. Two years earlier the 3rd-to-97th range was 18.0 cm; it keeps widening until 11 years 6 months, where it reaches 28.0 cm.

In height terms, a 7-year-old girl on the 3rd percentile (111.9 cm) stands about level with an average girl of 5 years 7 months (112.1 cm), while one on the 97th (132.7 cm) is about level with the median at 8 years 11 months (132.7 cm).

Girls compared with boys

At 7 years the boys' median is 122.0 cm; the gap to the girls' median is 0.2 cm, with boys taller. The girls' median is higher than the boys' from 10 years 9 months to 13 years 2 months, and lower at every other row of the table.

When to ask a pediatrician

Between age 4 and puberty, the site's guides suggest asking a pediatrician about growth under about 4 cm a year, a child who crosses downward through percentile lines, or a height far below what the parents' heights suggest.
