The average penis size, based on multiple scientific studies, is generally around:
- Erect length: approximately 5.1 to 5.5 inches (about 13 to 14 cm)
- Flaccid length: around 3.6 to 3.7 inches (about 9 cm)
- Erect girth (circumference): about 4.5 to 4.7 inches (around 11.7 to 12 cm)
- Flaccid girth: about 3.6 to 3.7 inches (around 9.3 cm)
Specifically, a comprehensive study with over 15,000 men found the average erect length to be about 5.1 inches with an average erect girth of 4.5 inches. Other similar studies confirm these ranges, noting most penises fall within this size spectrum. Differences exist across geographical regions and populations, but these averages are widely accepted in the medical community. It's also noted that the size of a flaccid penis is not a reliable predictor of erect size. The concerns about size often exceed the actual variation found in the populations studied.
