On average, girls experience significant growth during puberty, but the exact amount varies greatly. While there's no single definitive answer, several sources provide insights into the typical height increase.
Growth Before and After Menarche
The most significant growth spurt happens before the onset of menstruation (menarche). One source states that girls grow about 8 centimeters (approximately 3.1 inches) per year once puberty begins. [Source 1] Another source indicates that the largest growth, almost 3 inches, typically occurs around age 11 or 12. [Source 6]
Following menarche, growth continues, but at a considerably slower rate. Multiple sources suggest girls typically grow an additional 2 to 3 inches after their first period. [Source 1, Source 2, Source 6, Source 9, Source 10] Some studies show a range of 1 to 4 inches depending on the age of menarche. [Source 3, Source 4]
Total Growth During Puberty
While the exact figures vary, combining the pre- and post-menarche growth, a reasonable estimate for the total height increase during puberty is somewhere between 5 and 7 inches (or 13-18 centimeters). This is an average, and individual growth varies based on genetics and other factors.
Factors Affecting Growth
Several factors influence the total height gained during puberty, including:
- Genetics: Family history plays a significant role in determining final height.
- Nutrition: Adequate nutrition is crucial for optimal growth during puberty.
- Health: Underlying health conditions can affect growth.
Conclusion
Girls generally grow considerably during puberty, with a substantial increase before menarche and a smaller increase afterward. A reasonable estimate of total growth during puberty would be in the range of 5 to 7 inches.
