Penis Size Statistics (2026): The Complete Data
Last updated 2026 · Veale et al. 2015 (BJU International)
Every key penis-size statistic in one place, from the largest clinician-measured datasets — averages, percentiles, girth, volume, by country, and what partners prefer. Figures are cited and updated for 2026.
Key statistics at a glance
- The average erect penis is 13.1 cm (5.2 in) long and 11.7 cm (4.6 in) in circumference (Veale 2015, n=15,521).
- About 90% of men have an erect length between 10.4 cm (4.1 in) and 15.9 cm (6.2 in).
- The median erect length is 13.1 cm (5.2 in) — half of men are above it, half below.
- Only about 10% of men exceed 6 inches (15.2 cm) erect; roughly 1 in 400 exceeds 7 inches (17.8 cm).
- Average erect volume is about 142 ml.
- Micropenis (under ~9.3 cm / 3.7 in) affects roughly 0.6% of men.
- Average flaccid length is 9.2 cm (3.6 in) — and flaccid size barely predicts erect size.
- Reported national averages range from about 10 cm to 17.6 cm, but are self-reported and unreliable.
Where every man falls
Erect length follows a bell curve. Most men cluster near the average — the extremes are rare. Each bar is a slice of the population.
Population share by erect length (Veale 2015, n=15,521).

What counts as big?
A man at 6 inches (15.2 cm) erect sits around the 90th percentile — only about 10 in 100 are longer.
Penis size percentiles (erect length)
Modelled as a normal distribution from Veale 2015 (mean 13.12 cm, SD 1.66 cm for length). Read any row as: this percentile of men measure at or below this size.
| Percentile | Meaning | Erect length | Erect girth |
|---|---|---|---|
| 5th | Only 5% are smaller | 10.4 cm / 4.1 in | 9.9 cm / 3.9 in |
| 10th | Bottom 10% | 11.0 cm / 4.3 in | 10.3 cm / 4.0 in |
| 25th | Lower quarter | 12.0 cm / 4.7 in | 10.9 cm / 4.3 in |
| 50th | Median — dead average | 13.1 cm / 5.2 in | 11.7 cm / 4.6 in |
| 75th | Upper quarter | 14.2 cm / 5.6 in | 12.4 cm / 4.9 in |
| 90th | Bigger than 9 in 10 men | 15.2 cm / 6.0 in | 13.1 cm / 5.1 in |
| 95th | Top 5% | 15.9 cm / 6.2 in | 13.5 cm / 5.3 in |
| 99th | Top 1% | 17.0 cm / 6.7 in | 14.2 cm / 5.6 in |
Penis size by country
Reported national averages for erect length (entertainment-grade — see the disclaimer). All countries ranked.
Unweighted global average of national figures: 14.1 cm. Country averages are pooled from heterogeneous studies — many self-reported — and are not nationally representative. Treat them as rough, entertainment-grade estimates, not clinical fact.
What size do women prefer?
From Prause et al. 2015, which had women choose among 3D-printed models rather than recall numbers — a far more reliable method than surveys.
| Erect length | Erect girth | |
|---|---|---|
| One-time partner | 16.3 cm (6.4 in) | 12.7 cm (5.0 in) |
| Long-term partner | 16.0 cm (6.3 in) | 12.2 cm (4.8 in) |

Frequently asked questions
What is the average penis size?
The average erect penis is 13.1 cm (5.2 in) in length and 11.7 cm (4.6 in) in circumference, based on clinician-measured data from up to 15,521 men (Veale et al. 2015).
What is a normal penis size?
Normal is a wide range: about 90% of men measure between 10.4 cm (4.1 in) and 15.9 cm (6.2 in) erect. Anything in that band is statistically normal.
Is 6 inches big?
Six inches (15.2 cm) is above average. Only about 10% of men exceed it, so it sits around the 90th percentile.
What percentage of men are over 7 inches?
Roughly 1 in 400 men — under half a percent — exceeds 7 inches (17.8 cm) erect.
