Latex condoms are intended are intended to prevent pregnancy, HIV/AIDS, and other sexually transmitted infections. Condoms are sized by nominal width or the measurement across the rolled-up condom, and by length, the measurement from tip to the base when fully unrolled.

The truth is that most penises ( and dildos) will fit into a regular-size condom, or at the very least, a large one. Kai tells me, “Most average-size condoms will work on most penises. So if someone is telling you they can't use the condom you have because they're ‘too big’ for it, it's likely they don't want to use a condom.

Given that condoms go up to over nine inches in length and around two and a half inches in width — or roughly eight inches in girth — and the average penis size is estimated at just over five inches long and just under five inches around," Cole adds. "So the chances are slim of coming across a penis that legitimately doesn’t fit into any condom on the market."
