Are you the biggest in the room?
Pure probability, with a little swagger. Enter your erect length, pick a hypothetical group of adult men, and see the modeled odds. Your measurement never leaves this browser.
Your numbers
The underlying Veale 2015 length model has mean 13.12 cm and SD 1.66 cm. Newer studies differ.
A team, barracks, or real-world gathering is not a random clinical sample. This is a thought experiment, not a way to know another person's body.
Your modeled result
What happens as the group grows?
The line uses your approximate erect-length percentile as p, then calculates p^(N−1). The group starts at N=2. Exact tails are not established by samples of a few hundred.
Remember the ground rules
This assumes independent, randomly drawn adult men from the same reference distribution, a reliably measured length, and a valid normal approximation. The 2015 clinician-measured erect-length subset had n=692. A 2025 pooled review reported a different average using n=5,669 erect-length measurements; it should not be merged with the 2015 SD to fabricate a newer curve. If you don't know your measurement, each member of an identically sampled group of N people has approximately 1/N odds of being the longest.
