Growth in the year after 10 years

The median rises 2.5 cm in the next 6 months and 4.9 cm in the next 12, reaching 143.7 cm at 11 years.

This is the slowest stretch of the boys' table between ages 4 and 10: the smallest 12-month gain, 4.9 cm, starts at 9 years 7 months. After that the median speeds up again, to 7.8 cm in the 12 months from 12 years 9 months.

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 4.1 cm over the next 12 months.

Spread at 10 years

The 3rd-to-97th range covers 24.8 cm and the 25th-to-75th range 8.9 cm. Two years earlier the 3rd-to-97th range was 21.8 cm; it keeps widening until 13 years 9 months, where it reaches 30.3 cm.

In height terms, a 10-year-old boy on the 3rd percentile (126.7 cm) stands about level with an average boy of 7 years 9 months (126.6 cm), while one on the 97th (151.5 cm) is about level with the median at 12 years 4 months (151.5 cm).

Boys compared with girls

At 10 years the girls' median is 138.2 cm; the gap to the boys' median is 0.6 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. Puberty that starts before 9 in boys is also on that list.
