In terms of height growth and height growth related to bone age, average females stop growing taller two years earlier than average males. Peak height velocity (PHV) occurs at the average age of 11 years for girls and at the average age of 13 years for boys. [29]
[37]: 55–56 Males experience their growth spurt about two years later, on average, than females. During their peak height velocity (the time of most rapid growth), adolescents grow at a growth rate nearly identical to that of a toddler—about 10.3 cm (4 inches) per year for males and 9 cm (3.5 inches) per year for females.

During Tanner V, females stop growing and reach their adult height. Usually, this happens in their mid teens at 14 or 15 years for females. Males also stop growing and reach their adult height during Tanner V; usually this happens in their late teens at 16 to 17 years, [medical citation needed] but can be a lot later, even into the early 20s.
The male "growth spurt" also begins later, accelerates more slowly, and lasts longer before the epiphyses fuse. Although males are on average 2 centimetres (0.8 in) shorter than females before puberty begins, adult men are on average about 13 centimetres (5.1 in) taller than women. Most of this sex difference in adult heights is attributable to ...

The doctor will likely go over your child’s growth curve, which tracks height and weight over time, to confirm that your child is in a stable growing pattern.
Typically grows at a similar rate to the previous month, usually growing between 1 and 1.5 inches (2.5 and 3.8 cm) and gaining about 2 pounds (910 g). [23] Resting heart rate is usually between 80 and 160 beats per minute, and it typically stays within that range until the infant is about one year old. [18] Motor development
The average height of 19-year-old Dutch orphans in 1865 was 160 cm (5 ft 3 in). [77] From 1830 to 1857, the average height of a Dutch person decreased, even while Dutch real GNP per capita was growing at an average rate of more than 0.5% per year. The worst decline was in urban areas that in 1847, the urban height penalty was 2.5 cm (1.0 in).
