At what age range do girls typically enter puberty?

Girls typically enter puberty between the ages of 8 to 13 years. This range is important as it encompasses the onset of physical changes, such as breast development and the beginning of menstrual cycles, which mark significant milestones in female development. Knowing this age range is critical for understanding the diverse timelines for physical and emotional growth.

The start of puberty can vary for each girl, influenced by factors like genetics, nutrition, and overall health. The chosen age range reflects the average age at which many girls show the first signs of puberty, making it a foundational concept in child development studies. Understanding this timing helps caregivers support healthy growth and address any concerns that may arise during this transitional phase.
