While a girl's biggest growth spurt usually happens just before her period, she can still grow taller after starting her period. However, this growth is typically limited to a few inches, usually between two and three inches.
The exact amount of growth after menarche can vary significantly, with some girls growing more than others. This variation is likely influenced by several factors, including genetics and individual growth patterns.
It's important to note that most girls reach their full adult height by age 14 or 15.
