How to Use the Condom Size Calculator

- Enter your girth in inches (e.g., 5.0). Use values between 0.1 and 8 inches.
- Click “Calculate Size” to see your recommended condom size category.
- Review the size result, brand examples, and a brief explanation of why that size fits.
Note: All measurements must be in inches. Girth is the primary factor; length adjusts the recommendation for longer sizes.

Frequently Asked Questions
For length, measure from the base (where the penis meets the pubic bone) to the tip. For girth, measure around the thickest part of the erect penis using a flexible tape measure.
If your measurements fall between two size categories, it's generally safer to choose the larger size for comfort and to reduce the risk of breakage.
A properly fitting condom is less likely to slip off or break, providing better protection against pregnancy and STIs. An ill-fitting condom can be uncomfortable and less effective.
