Erect girth averages around 11.66 cm in a meta-analysis of 10 studies covering 10,141 men. Regional studies report higher mean circumference, including 12.53 cm measured bone-pressed in a Brazilian sample of 627. Across methods and samples, the takeaway is that normal variation is the main story, not a single fixed number.
Key Takeaways
- Meta-analysis showed average erect circumference of 11.66 cm (SD 1.10 cm) across 10 studies with 10,141 men
- Meta-analysis of 15 studies involving 15,521 men found average erect penile length of 13.12 cm (SD 1.66 cm, range 9.16-17.20 cm)
- Meta-analysis flaccid girth 9.31 cm (SD 0.90 cm) from 17 studies, n=13,719 men
- Global meta-analysis average flaccid length 9.16 cm (SD 2.49 cm) from 20 studies, n=15,521
- Ecuador average erect length 17.61 cm from national survey (n=unknown, self-reported adjusted)
Most men report average penis size, with significant natural variation across all age groups.

Interpretation
Erect Girth Interpretation
While these statistics might fuel locker room legends, the consistent global average of approximately 11.7 cm in circumference suggests that, despite regional variations, Mother Nature runs a remarkably standardized—and frankly, unimpressed—factory line.

Interpretation
Flaccid Girth Interpretation
While the global flaccid girth hovers remarkably close to 9.3 cm, proving the 'shower' and 'grower' debate a universal equalizer, it appears the world's locker rooms hold less dramatic geographical variation than one might nervously suspect.
