Find the Condom with the Right Fit and Feel for You

Does condom size matter?

Yes! Knowing your condom size is important for safe and pleasurable sex.

Some things about condom size to remember: 

  • Condom sizes can vary across brands.

  • An external condom that’s too big or too small can slip off or break, increasing the chances of pregnancy or infection transmission.

  • Likewise, an external condom that's the wrong size can reduce sensation during sex. It might feel restrictive, if it's too small. If it's too large, it can move around and be uncomfortable for both partners!

You can use this condom size chart and information about sizing across different brands to help choose condoms that work best for you!
