Every girlfriend who has ever been asked to pick up a ruler, this new study is for you: the journal BJU International researched 15,000 willing males and have determined the average length of the erect penis as … 5.16 inches. For context, that’s just a bit smaller than an iPhone 6. Meanwhile, the average flaccid penis is typically 3.63 inches long and 3.66 inches around. Okay.

The researchers want to use this data on average penis size for good: New York Daily News reports they hope to develop a penis size chart for doctors to use when counselling men with “small penis anxiety.” They also hope the numbers “reassure the large majority of men that the size of their penis is in the normal range.” Only 2.28% of men actually have an abnormally small or large penis (AKA a micro-penis) but 100% of us suffer when we have to hear about it.

Researchers also suggest that doctors use the penis size chart to help men find well-fitting condoms. That would thwart men from not wanting to use condoms because they feel too tight, as well as keeping condoms from falling off mid-coitus. Hey, why don’t we get one of those metal sizing plates like at the shoe store?

In other interesting penile news, the study also found no correlation between foot and junk size, or any differences linked to race. Old wives tales, all! But the Daily News had one caveat: “[M]ost of the study participants were of European and Middle Eastern descent and a full comparison could thus not be made.” Anyone up for a follow-up study?
