Wondering how you measure up? The average penis size has been studied extensively, and the numbers might surprise you. Whether you’re curious about length, girth, or how genetics play a role, this guide breaks down the facts—no myths, just research-backed data.
What Is the Average Penis Size?
Multiple global studies have measured flaccid and erect penises to determine averages. Here’s what the research shows:
Average Erect Penis Size:
📏 Length: 5.1 – 5.5 inches (13 – 14 cm)
📏 Girth: 4.5 – 4.7 inches (11.5 – 12 cm)
Average Flaccid Penis Size:
📏 Length: 3.4 – 3.7 inches (8.5 – 9.5 cm)
📏 Girth: 3.5 – 3.9 inches (9 – 10 cm)
(Sources: British Journal of Urology, World Health Organization)
Does Size Vary by Country?
Studies suggest slight regional differences, but not as extreme as stereotypes imply:
🌍 Largest averages: Congo, Ecuador, France (~6.3 inches)
🌍 Smallest averages: North Korea, Cambodia, Thailand (~4.5 inches)
🌍 U.S. average: ~5.3 inches
Note: Genetics, nutrition, and measurement methods affect results.
Does Penis Size Matter?
-
Most women prefer girth over length (Journal of Sexual Medicine).
-
Only 18% of women say size is very important (YouGov survey).
-
Technique & confidence matter more than sheer size.
Can You Increase Penis Size?
⚠ Most “enlargement” methods are ineffective or risky. Here’s the truth:
❌ Pills & creams – No scientific proof.
❌ Penis pumps – Temporary swelling only.
❌ Jelqing – Can cause injury.
✔ Surgery (phalloplasty) – High risk, minimal gains (~1 inch).
Best advice? Focus on sexual health, stamina, and pleasure techniques instead.
When to See a Doctor
Seek medical advice if:
-
Your erect length is under 2.75 inches (micropenis).
-
You experience sudden shrinkage (could indicate hormonal issues).
-
You have pain or dysfunction during erections.
