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.
By doing this, doctors can track a child's growth over time and monitor how a child is growing in relation to other children. There are different charts for boys and girls because their growth rates and patterns differ. For both boys and girls there are two sets of charts: one for infants ages 0 to 36 months and another for ages 2 and above.
Growth charts have been constructed by observing the growth of large numbers of healthy children over time. The height , weight , and head circumference of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately.
The following calculations are used for males and females respectively: Male = (father’s height + mother’s height + 13 cm)/2 Female = (father’s height-13 cm + mother’s height)/2. [3] Head circumference and length clinical growth chart for a male child from birth to 36 months.
The median (50th percentile) growth curves for males and females 0−20 years in the United States. The study of height is known as auxology. [11] Growth has long been recognized as a measure of the health of individuals, hence part of the reasoning for the use of growth charts.

The 2000 CDC growth charts - a revised version of the 1977 NCHS growth charts - are the current standard tool for health care providers and offer 16 charts (8 for boys and 8 for girls), of which BMI-for-age is commonly used for aiding in the diagnoses of childhood obesity. [1]
Bone maturation is delayed with the variation of normal development termed constitutional delay of growth and puberty, but delay also accompanies growth failure due to growth hormone deficiency and hypothyroidism. [39] [40] Recent studies show that organs like the liver can also be used to estimate age and sex, because of the unique feature of ...
Maximal adult height is achieved at an average age of 15 years for an average female and 18 years for an average male. Potential fertility (sometimes termed nubility) usually precedes completion of growth by 1–2 years in females and 3–4 years in males. Stage 5 typically represents maximal gonadal growth and adult hormone levels.
