Most girls stop growing and reach their adult height by 14 or 15 years old, or a couple of years after menstruation begins. However, there's no exact timing, and it can vary depending on the individual. The timing of puberty plays a crucial role in determining when a girl reaches her full adult height.
Factors that influence a girl's growth:
- Genetics: A girl's height is significantly influenced by the heights of her parents.
- Puberty: During puberty, a growth spurt occurs, and girls typically stop growing shortly after their first menstrual cycle.
- Nutrition: A balanced diet with sufficient nutrients is vital for proper growth and development.
- Health conditions: Certain health conditions can affect a girl's growth.
Important Note: While most girls stop growing by 14 or 15, some may continue to grow until they are 16 or even 18 years old.
