A meta-analysis of 20 studies covering 15,521 men reported a mean erect length of 13.12 cm. Separate reviews of more than 9,000 participants placed average erect girth at 11.66 cm. Individual country studies range several centimeters above or below these global figures.
Key Takeaways
- Meta-analysis showed mean erect penile circumference of 11.66 cm (SD 1.10 cm, 95% CI 11.41-11.91) from 10 studies n=9,706
- Meta-analysis of 20 studies with 15,521 men found mean erect penile length of 13.12 cm (SD 1.66 cm, range 9.16-17.39 cm)
- Mean flaccid girth 9.31 cm (SD 2.91 cm, 95% CI 9.01-9.62) from 14 studies n=10,407 per Veale
- Veale meta-analysis reported mean flaccid length 9.16 cm (SD 2.49 cm, 95% CI 8.95-9.37) from 17 studies n=13,719 men
- Stretched flaccid length mean 13.24 cm (SD 1.89 cm) as proxy for erect from 9 studies n=6,768
Most people fall within average dick size, with extreme sizes being much rarer.

Interpretation
Size Variations Interpretation
The data suggests that, despite its cultural obsession, the average penis is remarkably average, with a predictable 13-14 cm range, but this modest ruler is subject to a surprising number of influences—from BMI and smoking to altitude and diet—proving that while size varies, the capacity for male anxiety about it appears universal.
