At ONE® Condoms we are constantly innovating with new materials, sizes and styles to make safer sex feel as pleasurable as possible - powered by the latest condom technology.
We provide a variety of condom styles in a standard condom size, including the ONE® Flex® graphene condom, Glowing Pleasures™ glow-in-the-dark condom, Super Studs™ textured condom, Pleasure Plus®, and Tattoo Touch®. ONE® also has an extra large condom called Legend XL™. Because we know that many people struggle with condom fit, we also launched the MyONE® Custom Fit® line with 52 condom sizes. MyONE features sizes snugger and larger than any other brand, and is also hyperthin and extra lubricated.
What is a standard condom size?
In order to try and fit a lot of different penises, there is a "standard condom size" that was developed years and years ago. Standard condoms are typically around 7 inches long with a nominal width of 53mm (2.09 inches). Many people use that condom size successfully and have great experience with condoms. However, others experience condom slippage, squeezing, bunching or erection loss when condoms are too tight.
What if I struggle with condom fit?
If you struggle with standard condoms not fitting correctly, you're not alone! Check out our MyONE® Custom Fit® line that has more sizes than any other brand. We make it easy to find your perfect fit condoms with plenty of online tools and resources. To start, you'll first need to find your MyONE FitCode (aka size code), which is a combination of a Girth Number (ex. 53) and a Length Letter (ex. H) to get your FitCode (ex. 53H).
What is the (average) nominal width of a condom?
Condoms are a medical device, and each condom style has specifications they must meet for nominal width, length, and thickness. Manufacturers measure condoms using two dimensions – lay flat width (often called nominal width) and length. The lay flat width is the measurement of the condom when it is laid flat. The length and width are typically defined in millimeters during the manufacturing process.
People use different dimensions to measure their penises, using circumference or girth to describe thickness around the penis. Girth is the same as circumference. The MyONE sizing tools then convert the penis girth measurement/circumference into a recommended condom nominal width. People can't measure their penis nominal width, because otherwise they'd have to flatten out their penis…ouch! Our sizing tools also recommend a condom circumference slightly tighter than your penis circumference to ensure the condom will stay snug in place during use.
How do the MyONE FitCodes work?
MyONE has ten different Length Letters, ranging from C (4.7" in condom length) to M (9.3" in condom length). Fun fact: We didn't use the letters A and B because one day we hope to introduce two shorter length options.
We have nine different Girth Numbers, ranging from Super Snug 45 (45mm nominal width) to 64 Super Wide (64mm nominal width).
What is a proper condom fit?
A condom should be long enough to cover the entire shaft of the penis from base to tip. But it should not be so long that the excess latex hangs at the tip, or bunches at the base. The more excess latex bunching at the base, the tighter the condom will feel.
When it comes to girth, the condom should be snug enough so that it stays in place. But it should not be so tight that it causes discomfort, squeezing, or erection loss.
Our MyONE® Custom Fit® recommendations will recommend a condom length slightly longer than your penis length to ensure it is long enough. They will also recommend a condom circumference slightly tighter than your penis circumference to ensure that the condom will stay in place. But this is also why we offer the free sample kits (just pay shipping) so you can test some sizes before you buy. Some people may prefer their condoms a little snugger or loose, for example. So testing some samples is key to finding your perfect fit.

For MyONE® Custom Fit®:

Understanding Nominal Width vs. Penis Girth
Nominal width (the flat width of the condom) is different from penis girth (circumference). Nominal width is the width of the condom when laid flat. Penises are measured in circumference (around the thickest part of your erection). Our sizing tools will convert your penis circumference/girth into one of the MyONE® Girth Numbers (45-64); those numbers also correspond to the nominal width of the condom.

Frequently Asked Questions
What if I'm between sizes?
If you're between two sizes, we recommend trying both. Many people prefer a slightly snugger fit for security, while others prefer a bit more room for comfort. Can I order sample packs?
Can I sample different condom sizes?
Yes! There are two ways to sample MyONE® Custom Fit®:
First option: If you measure and find your FitCode, you will find a sample kit for that size on the corresponding product page. The 2-count sample kits come with the size you measured, plus another close size. If the initial sample kit is not a great fit, contact us. We will recommend and send a sample kit of another size free of charge.
Second option: No time to measure? Don't want to measure? Check out the MyONE® Quick Samplers either in the Snug, Classic, or Large range. Each sample kit comes with three different FitCodes to try, plus the FitKit measuring tool so you can re-measure and adjust as needed.
If you want to try a bunch of the different ONE® Condom styles, try one of our variety packs including Premium Pleasures™ and Mixed Pleasures™.
How do I know if a condom fits properly?
A properly fitting condom should:
- Unroll easily to the base without restriction
- Feel snug but not tight or painful
- Not be so long that the excess latex hangs at the tip, or bunches at the base.
- Stay in place during use
