Penile growth typically begins during puberty, around ages 9 to 14, and continues until the late teens or early twenties. The following are approximate average flaccid (non-erect) penis lengths by age:
- Ages 10-11: 1.6 to 3.1 inches (4.1 to 7.9 cm)
- Age 12: 2.0 to 4.0 inches (5.1 to 10.2 cm)
- Age 13: 2.0 to 4.7 inches (5.1 to 11.9 cm)
- Age 14: 2.4 to 5.5 inches (6.1 to 14.0 cm)
- Age 15: 3.1 to 5.9 inches (7.9 to 15.0 cm)
- Age 16: 3.9 to 5.9 inches (9.9 to 15.0 cm)
- Age 17: 3.9 to 6.3 inches (9.9 to 16.0 cm)
- Age 18: 4.3 to 6.7 inches (10.9 to 17.0 cm)
By age 16, many individuals have reached their adult penis size, with an average erect length between 5 and 7 inches (12.7 to 17.8 cm).
Average Penis Size by Country
Global studies indicate that average erect penis lengths vary by country. For instance, men in Ecuador have an average erect length of 17.61 cm (6.93 inches), while those in Cambodia average 10.04 cm (3.95 inches). Overall, the global average erect penis length is approximately 13.58 cm (5.35 inches).
It’s important to note that these figures are averages, and individual sizes can vary widely within any population. Additionally, penis size does not correlate with factors like fertility or sexual satisfaction. Cultural myths linking penis size to attributes such as height, hand size, or shoe size have been debunked.
Understanding these variations can help dispel common misconceptions and promote a healthier body image.
