How useful and accurate are condom size calculators?

Science says men don’t wear condoms because they don’t fit. Could a condom size calculator solve the equation?

As a woman without a penis, I’ve never given much thought to the process of buying condoms, let alone what size you’re supposed to buy, or how you know what size you are. I’ve heard of Magnums and I’ve heard of full size condoms, but that’s about it. And, in the end, my knowledge is not so far removed from that of many men. A quick search of Reddit will turn up a number of men looking for advice on what size condom to buy or how to measure their dicks to determine the right one. “Hey, uh, I’m 5.5-5.9 inches in circumference and about 7.2 inches in length,” one user wrote. “I’ve read that the penis should be 80-90% the size of the condom for the lowest risk of slipping/breaking. I don’t know if that’s true, and also when I look at condoms they say 53 millimeters, 56 millimeters and 60 millimeters, but as I am 47 millimeters wide, I am confused. Can you help me?

He’s not the only confused penis owner. According to a 2017 study, only a third of American men use condoms, which according to The New York Times, is partly because of their perceived poor fit. Another study confirmed this reasoning, finding that 83% of men had shorter penises than standard condoms (the average penis length is between 5.1 and 5.5 inches and the standard condom length is 7. 25 to 7.8 inches). When used incorrectly – including when they don’t fit properly – condoms are only 85% effective, compared to 98% if used perfectly every time.

Like the authors of yet another one One study once wrote, “Condoms need to fit snugly to protect against fluids and exposed skin that could lead to contracting STDs or pregnancy.” These authors explain that, in finding the right size, “girth (the width of an erect penis) is the most important factor, not length.” However, they continue, “most condom manufacturers don’t state their normal width, let alone base their sizes on circumference.” As a result, “men complain about the lack of simplicity and intuitiveness in finding a condom that suits them”.

What is the problem that condom size calculators aim to solve. There are a number of such online measurement sites, all of which require users to enter their penis size (girth and length) before suggesting a condom brand and model suitable for their specific cock. So, for example, our friend from the Reddit post above would find a Pasante King Size condom (5.2 to 5.9 inches in circumference) to be a “tight” fit, while a Durex XXL (5.4 to 6 inches in circumference) would be a “normal” fit – at least according to the calcSD calculator, anyway. Another calculator, on, produces the same results, as does The Big Dick Guide. The r/BigDickProblems subreddit also has a few other condom sizing links in its FAQ (one person in the group even shared a very helpful guide to sizing).

But, as several commenters on Reddit have noted, these calculators don’t always have the answer either. “The two newest condoms I’ve tried are the Trojan Supras (too tight, don’t go all the way down) and the Bareskin Magnums (perfect length, but with vertical wrinkles at the top near the head)”, said one user. “Magnums are 100 times more comfortable than Supras, and condom size calculators say they should fit, but I don’t know what to think of the creases. Are the wrinkles near the top normal or does that mean are they too big?”

Because you (obviously) can’t try them on in stores, for those wondering about their size, it’s worth buying several sizes of condoms and trying them on – even using a condom calculator, which can give you a good idea of ​​which ones to start with. Most sex shops also carry single condoms from many brands, so you can buy a few and try them on without breaking the bank.

And if you’re a Magnum, congratulations man!
