Condom Calculator: Find Your Perfect Fit

This tool will help you find the right condom size for maximum comfort and effectiveness.

How to Use the Condom Size Calculator

To use this calculator, simply enter the penis circumference in millimeters in the input field and click on the “Calculate” button. The calculator will compute the recommended condom width based on the input circumference.

How It Calculates the Results

The calculator first converts the entered circumference into diameter using the formula: diameter = circumference / π. It then calculates the width by dividing the diameter by 2, as condoms are measured by their flat width when laid. The result displayed is the recommended condom width in millimeters.


This calculator provides an estimated recommended condom width based on the entered circumference. It does not account for other factors like material, thickness, or personal preferences. Always use the condom that best fits and feels comfortable for you.
