When do people get their final growth spurt?

Most people experience their final growth spurt during puberty, which typically occurs between ages 10 and 14 for girls and 12 and 16 for boys. This growth spurt is often marked by a rapid increase in height and is influenced by hormonal changes, particularly the increase in sex hormones. After this period, growth plates in the bones close, signaling the end of height increase, usually by the late teens to early twenties.
