Erect length chart (inches)
How rare is 6 inches? What share of men are under 5? This chart answers it for every common size, based on the largest systematic review of measured men (Veale et al. 2015, BJU International, n = 15,521). All values are erect and measured by researchers, not self-reported.

|---|---|---|
| 4.0 in (10.2 cm) | 4% of men | 96% (963 in 1,000) |
| 4.5 in (11.4 cm) | 15% of men | 85% (846 in 1,000) |
| 5.0 in (12.7 cm) | 40% of men | 60% (600 in 1,000) |
| 5.5 in (14.0 cm) | 70% of men | 30% (304 in 1,000) |
| 6.0 in (15.2 cm) | 90% of men | 10% (101 in 1,000) |
| 6.5 in (16.5 cm) | 98% of men | 2% (21 in 1,000) |
| 7.0 in (17.8 cm) | 99.8% of men | about 2 in 1,000 |
| 7.5 in and above (19.1 cm+) | more than 99.9% | fewer than 1 in 1,000 |

Erect girth chart
Girth is the circumference around the shaft. The average is 11.7 cm (4.6 in) — more in our average girth explainer.
How to read this chart
"Longer than 90% of men" means that if you lined up 100 men, 90 would be shorter. It's a position in a queue, not a grade. The middle of the curve is wide: everything between roughly 11.5 and 14.8 cm is statistically ordinary.
The percentages come from a normal distribution fitted to the measured data. That works well in the middle, but at the extremes (below 10 cm or above 17 cm) real-world data is thinner and the numbers are less precise. More on that in understanding percentiles.
Why most men misjudge where they stand
- Looking down at yourself foreshortens length. A side view or a ruler is far more accurate.
- A pubic fat pad can hide part of the shaft. Measure from the pubic bone, pressing gently into the fat.
- Porn and social media show the far right tail of the curve as if it were normal.
The exact protocol: how to measure accurately.
