When does a 12 year old girl gets a growth spurt?

A 12-year-old girl typically experiences a growth spurt during puberty, which often starts between the ages of 9 and 14. The most significant growth usually occurs around ages 11 to 13, with girls generally reaching their peak height around age 12. Hormonal changes, particularly the increase in estrogen, play a crucial role in this growth phase. However, the timing can vary widely among individuals.
