Compare your size to clinical reality, calmly.
A research-grade percentile from 103,588 clinical measurements across 20 peer-reviewed studies. No marketing claims. No self-reported data. No follow-up emails.
Normal distribution from Veale et al. 2015. The terracotta line marks your value (13.1 cm); the dashed line is the mean (13.12 cm). The shaded band is ±1 SD — the middle 68% of measured men.
Girth percentile 51st. Mean 11.66 cm, SD 1.10 cm — Veale et al. 2015.
You are almost exactly average.
The 50th percentile means half of measured men fall below your value and half above. Within one standard deviation of the mean — the band from the 16th to the 84th percentile — sits 68% of all men. You are inside that band.
Veale et al. 2015, BJU International. Meta-analysis of 15,521 men; SD 1.66 cm for length.
The number is not the question. The next sections cover what partners actually say they prefer, why size worry persists when the maths is calm, and what the cognitive-behavioural research finds actually helps.
