Bros, grab your rulers.
An enlightening new study published in the British Journal of Urology International purports to have determined the worldwide average penis size.
The study pulled data from 17 previous academic papers that included the measurements of 15,521 men in total. From there, the researchers determined that that average flaccid penis is 3.61 inches in length and the average erect penis is 5.16 inches in length. As for girth, the average penis is 3.66 inches when flaccid and 4.59 inches when erect.
With the latest research in mind, Mashable asked brave staffers to draw what they believe is the average penis size in comparison to the study's findings.
