Penis size chart
Type a number into any calculator and it lands somewhere on a curve. This chart shows where — every erect length and girth, inch by inch, mapped to its percentile from clinician-measured data (Veale 2015, n=15,521).

How to read it
The percentile is the share of men you're longer (or thicker) than. The average sits at the 50th — and the average band is wide, covering roughly the middle third of men. Most cluster within a couple of centimetres of the mean; the tails are genuinely rare.
