Sultan Kosen, Tallest Man In The World, 2 Meters 47 Centimeters, Turkey

Height, like other phenotypic traits, is determined by a combination of genetics and environmental factors. A child's height based on parental heights is subject to regression toward the mean, therefore extremely tall or short parents will likely have correspondingly taller or shorter offspring, but their offspring will also likely be closer to average height than the parents themselves. Genetic potential plus nutrition minus stressors is a basic formula. Humans grow fastest (other than in the womb) as infants and toddlers, rapidly declining from a maximum at birth to roughly age 2, tapering to a slowly declining rate, and then during the pubertal growth spurt, a rapid rise to a second maxima (at around 11-12yrs for female, and 13-14yrs for male), followed by a steady decline to zero. On average, female growth velocity trails off to zero at about 15 years, whereas the male curve continues for approximately 3 more years, going to zero at about 18. These are also critical periods where stressors such as malnutrition (or even severe child neglect) have the greatest effect. Conversely, if conditions are optimal then growth potential is maximized; and also there is catch-up growth – which can be significant – for those experiencing poor conditions when those conditions improve.
Moreover, the health of a mother throughout her life, especially during her critical periods, and of course during pregnancy, has a role. A healthier child and adult develops a body that is better able to provide optimal prenatal conditions. The pregnant mother's health is important as gestation is itself a critical period for an embryo/fetus, though some problems affecting height during this period are resolved by catch-up growth assuming childhood conditions are good. Thus, there is an accumulative generation effect such that nutrition and health over generations influences the height of descendants to varying degrees.
The age of the mother also has some influence on the her child's height. Studies in modern times have observed a gradual increase in height with maternal age.
