What this size means
Below the average, and well inside the normal range. Clinicians put 90% of men between about 10.4 and 15.9 cm erect, and this size sits within that band. "Below average" is a statistical position, not a diagnosis: the medical cutoff for micropenis is under about 9.3 cm, measured stretched or erect.

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 10 cm. Girth is measured around the thickest part of the shaft.
