What is the average penis size in inches?

The average erect penis is 5.16 inches (13.12 cm) long and 4.59 inches (11.66 cm) around. That’s not a guess. It comes from Veale et al. 2015 in BJU International, which pooled clinician measurements of 15,521 men — the biggest dataset on the planet. Median length is 5.2 inches (13.1 cm), and about 90% of men land between 4.1 and 6.2 inches (10.4–15.9 cm) erect. If you’re in that band, you’re normal. Full stop.

Length is only half the story. Flaccid averages 3.6 inches (9.16 cm), stretched runs 5.21 inches (13.24 cm), and a 5-inch girth already parks you near the 83rd percentile. Thickness climbs the scale faster than anyone expects, so don’t sleep on it.

Want to see where every inch lands? Here’s the map:

• 5 in → ~40th percentile (just under average)
• 5.5 in → ~70th percentile
• 6 in → ~90th percentile, about 1 in 10 men
• 6.5 in → ~98th percentile, about 1 in 50
• 7 in → ~99.7th percentile, about 1 in 400

One hard rule: ignore those color-coded “average by country” maps. They run on self-reported numbers, and men round up. Always.

And before you sweat the ruler, know this — what women actually prefer rarely matches the locker-room mythology.
