Height percentiles for 10-year-old boys
A percentile tells you how many boys of the same age are shorter: at the 75th percentile, a boy is taller than 75 out of 100 boys 10 years old.
| Percentile | At 10 | At 10½ |
|---|---|---|
| 5th | 4'2.5" (128 cm) | 4'3" (130 cm) |
| 10th | 4'3.5" (130 cm) | 4'4" (132 cm) |
| 25th | 4'5" (134 cm) | 4'5.5" (137 cm) |
| 50th (median) | 4'6.5" (139 cm) | 4'7.5" (141 cm) |
| 75th | 4'8.5" (143 cm) | 4'9.5" (146 cm) |

How much will a 10-year-old boy grow?
At the median, boys grow about 1.9 in (4.9 cm) between 10 and 11. A boy of average height at 10 has reached about 78% of adult height and still has around 15.1 in (38 cm) to go.
Most 10-year-old boys have not started their growth spurt. Growth is steady, a little under 2 inches (5 cm) a year, and some boys show the first signs of puberty.

Is my son’s height normal?
Any height between roughly the 3rd and 97th percentile is common. What matters more is the trend: a child who stays on the same percentile line over the years is usually growing normally. Talk to a doctor if your child is below the 3rd percentile, much shorter than the parents’ heights suggest, has stopped growing, or has crossed two major percentile lines downward.

Frequently asked questions
Is 4'10" tall for a 10-year-old boy?
Yes. 4'10" is about the 82nd percentile for boys aged 10, so taller than roughly 82 out of 100. Being tall at 10 can also mean an early growth spurt, so it doesn’t guarantee being tall as an adult.
Is 4'5" short for a 10-year-old boy?
4'5" is about the 17th percentile for boys aged 10: below average but well within the normal range. Many boys who are shorter at 10 simply start puberty later and catch up.
How much will a 10-year-old boy grow?
At the median, boys grow about 1.9 in (4.9 cm) between 10 and 11, and about 15.1 in (38 cm) in total before adulthood. The real number depends on genetics and puberty timing.
