At what age range do girls typically enter puberty?

Girls typically enter puberty within the age range of 8 to 13 years. This period marks significant physiological and hormonal changes that signal the development of secondary sexual characteristics and the onset of menstruation. The onset of puberty can vary significantly among individuals; however, most girls will begin to show signs of puberty—such as breast development and the growth of pubic hair—during this timeframe.

The variation among individuals can be influenced by several factors, including genetics, nutrition, and environmental factors. This age range is crucial as it reflects the average timeline for physical and hormonal development in females, making it the most accurate choice regarding when girls generally begin puberty. Understanding this age range is important for recognizing normal growth patterns and addressing any potential concerns related to early or delayed puberty.
