When erect, the average penis swelled to 5.2 inches in length and 4.6 inches in circumference.
Wonder where you fit in? Here’s more context: Guys in the 95th percentile for erect length - meaning out of 100 men, only five would have longer penises - measured about 6.3 inches. Men in the 5th percentile averaged about 4 inches.
So anything between around 4 inches and 6.3 inches when erect would cover 90 percent of guys.
The researchers also explored some of the most common “indicators” of penis size to see if there was an actual connection. Height was slightly related, meaning that the taller men were, the larger their erect penises tended to be - but only to a small extent, says study author Dr David Veal.
On the other hand, other measurements that have been thought to point to penis size were actually pretty useless. Factors like a guy’s weight, length of his index figure, and foot size weren’t consistently predictive.
Even if your penis size is a little on the shorter side of average, that’s no reason to worry: “That’s not an issue to 85 per cent of women,” says Dr. Veale.
