Growth and Your 13- to 18-Year-Old

eens undergoing puberty will have many changes in their developing bodies as growth surges and muscles change shape. Often these changes are quite dramatic.
There's a very broad range of time in which kids hit puberty-related growth spurts:
  • Most girls start their sexual development between the ages of 8 and 13, and have a growth spurt between the ages of 10 and 14.
  • Most boys start developing sexually between the ages of 10 and 13, and continue to grow until they're around 16.

Growth and Changes During Puberty

Puberty — or sexual maturation — is a time of dramatic change for both boys and girls. Hormone-driven changes are accompanied by growth spurts that transform kids into physically mature teens as their bodies develop.
It's important for them to have healthy eating habits, a well-balanced diet, and some physical activity each day to ensure continued growth and proper development during these years.

Changes in Girls

These characteristics describe the sequence of events in girls as they go through puberty:
  • Breasts begin to develop and hips become rounded.
  • The increase in the rate of growth in height begins.
  • Pubic hair begins to appear, usually within 6 to 12 months after the start of breast development.
  • The uterus and vagina, as well as labia and clitoris, increase in size.
  • Pubic hair is well established and breasts grow further.
  • The rate of growth in height reaches its peak by about 2 years after puberty began (average age is 12 years).
  • Menstruation begins, almost always after the peak growth rate in height has been reached (average age is 12.5 years).
Once girls start to menstruate, they usually grow about 1 or 2 more inches, reaching their final adult height by about age 14 or 15 years (younger or older depending on when puberty began).
