How it compares
Drawn to scale against the 13.1 cm average and a few objects you can picture.
What this size means
Clearly above average, and still inside what clinicians actually measure: roughly 1 in 103 men are longer. Bigger is not automatically what partners pick. In a study using 3D-printed models, women chose about 16 cm long and 12.2 cm around for a long-term partner (Prause et al., 2015).

How this is measured
These figures use bone-pressed length, measured from the pubic bone, the way the reference nomograms were taken. Measured without pressing into the fat pad, the same erection reads about 16 cm. Girth is measured around the thickest part of the shaft.
