Condom Size Calculator: Find Your Best Condom Fit by Girth and Width

Quick start: enter or filter by your approximate condom width, brand, material, shape, or feel preference. If you know your erect girth, divide it by about 2.25 to estimate a starting nominal width, then compare options below.

Not sure where to begin? Use the complete condom size chart, or jump to fit guides for condoms that feel too tight, condoms that keep slipping off, and how to know if a condom is too big.

We designed this calculator to make it easier to pinpoint condom size options that fit you best. Unlike our condom size charts that force you to scroll through dozens of separate lists and read each size, this calculator features custom searches of over 100 condoms all at once.

It will identify condoms based on a number of personal preferences including size range, shape, lubrication, material and texture. You can type descriptors in the search box like “thin”, “wide head”, “flavored” or even a brand name such as “Durex”, for example. Or you may search based on nominal dimensions.  Scroll down for in-depth instructions. Or just start playing with it and see what you can find!

Of course, the calculator is not as helpful if you don’t know your erect size.  Read our tips for measuring penis size. Also, it’s important to understand what condom length and base width actually mean.  For example, if you measure 4.8inches wide (the average erect girth of a North American guy according to a recent study), will you fit a 2.0 inch wide condom? The answer is YES. However, comfort may vary depending on your shape, the elasticity and lubrication of the condom.

How to Use

There are many ways to use the calculator and search condoms.  Here are some guidelines.

Select Multiple Characteristics:

The basics principle of the calculator is to select many specifications to generate more search results. Do not select one specification from the drop down menus.  It is best to select multiple specifications in order to find a variety of condoms.

For example, if you select from the “Length” drop menu one size (say, 7.48″/190mm) you are commanding the calculator to only find that exact measurement. The calculator will only show the one condom which matches 7.48 inches. After selecting this specification, you will find that no other search options are available (e.g. “width” is grayed out). This is because there are no more condoms available with the specification you selected.

De-Select Characteristics:

You can delete specifications by simply clicking on them. This will also help broaden your search. Don’t be afraid to play around a bit. Select many lengths and widths.

Exact Keywords Search Box:

Use the search box to narrow the search by specific condom names, brands and characteristics such as “thin”, “studded”, non-lubricated”. Be aware that it will only generate results of an exact match to what you type. So play around with adjective, spaces, and hyphens. For example, typing “nonlubricated” vs. “non-lubricated” (with a hyphen) will give different results.   

Condom Ratio to Penis Girth:

Base width: We advise selecting condom base width that is within 10% to 20% ratio of penis circumference. Remember, base width is measured by the condom laying flat. This is not the circumference. To translate your penis girth to condom width divide your penis girth by 2.25 (Read how we got this recommended figure).

Length: Condom length is far more elastic and versatile than width and can accommodate many different penis sizes. We advise selecting condom measurements that are longer than exact penis length, about half an inch (24mm) longer than your penis. Consider that there needs to be enough room at the reservoir tip (enough material to pinch between your thumb and index finger or about 0.5″/13mm length) to contain sperm. Most North American condoms are between 7.0″/ 180mm and 7.5″/190mm long. This will suit a broad range of guys who measure 5.0″/127mm to 6.5″/165mm long.
