Frequently Asked Questions
Evidence-based answers verified by urological literature.
What is the true scientifically proven average penis size?+
According to the largest clinical meta-analysis published in the British Journal of Urology International (Veale et al. 2015) examining 15,521 clinically measured men, the average erect length is 13.12 cm (5.16 inches) and the average erect girth is 11.66 cm (4.59 inches).
Is 14 cm (5.5 in) or 15 cm (6 in) average or big?+
An erect length of 14 cm (5.5 inches) exceeds roughly 70.2% of men worldwide. An erect length of 15 cm (5.9 inches) exceeds 87.1% of men, placing you in the top 13% globally.
How do you measure bone-pressed erect length (BPEL) accurately?+
Place a rigid ruler along the top of the erect penis, press firmly into the pubic bone (compressing fat pad) until you contact the bone, and measure straight to the tip of the glans.
Why do internet surveys claim much larger sizes?+
Self-reported surveys suffer from response bias and self-inflation, typically exaggerating sizes by 1.5 to 2.5 cm (0.6 to 1.0 inch). Only clinical studies with measurements conducted by medical practitioners represent true population distributions.
