In the never-ending search to find out what’s really “normal” down there, a new review of penis studies has arrived. (For more on how your guy stacks up against the average man: Is Your Guy Normal When It Comes to Sex?) The research is published in BJU International—and is said to be the first attempt to create a formal systematic review of penile measurements. In their research, scientists collected data from 17 studies involving over 15,000 men who underwent penis size measurements by health professionals, determining the following averages for penis length and circumference (we went ahead and converted to inches for you):
Average length of a flaccid penis: 3.6 inches
Average length of a flaccid stretched penis (we’re still pondering the method on this one): 5.2 inches
Average circumference of a flaccid penis: 3.7 inches
Average length of an erect penis: 5.2 inches
Average circumference of an erect penis: 4.6 inches
The point of the handy diagram (officially known as a nomogram)? “We believe these graphs will help doctors reassure the large majority of men that the size of their penis is in the normal range. We will also use the graphs to examine the discrepancy between what a man believes to be their position on the graph and their actual position or what they think they should be,” said David Veale, M.D., who led the review.
We’re not saying you should print out the chart and leave it on your nightstand for comparison, but hey, it’s always good to be informed, right?
