Penis size has always been a topic of curiosity, yet it’s often misunderstood. In this article, you’ll discover average penis lengths by age groups and country data from recent studies. These are statistical averages — personal variation is perfectly normal.
What Is the Average Penis Length?
Global research suggests the average erect penis length is around 13.2 cm (5.2 inches). This number varies based on geography, ethnicity, and age. For example, in Turkey, the estimated average is around 12.8 cm, while the U.S. averages closer to 13.5 cm.
Average Penis Length by Country
- 🇨🇩 Congo: 17.9 cm
- 🇪🇨 Ecuador: 17.7 cm
- 🇺🇸 USA: 13.5 cm
- 🇹🇷 Turkey: 12.8 cm
- 🇰🇷 South Korea: 9.6 cm
Penis Growth by Age
In teenage years (15–20), penis length is still developing. Most men reach full adult size by age 21–22. After age 40, slight reductions in size may occur due to changes in erection quality — not actual shrinkage.
Final Thoughts
Penis size varies widely and doesn’t define sexual performance. Comparing yourself to averages is natural, but confidence, communication, and emotional connection matter more. Size alone does not determine pleasure.
