Step 1: Measure your circumference
Use a flexible tape measure. Measure the circumference of your erect penis at its widest point. Note the measurement in centimeters.
Step 2: Find your nominal width
The nominal width of a condom corresponds to half the width when laid flat. Use the table below to find your ideal size.

Step 3: Try and adjust
A well-fitting condom should neither squeeze nor slip. If it's uncomfortable, try the next size up or down. Comfort is essential for safety.
Why the right size matters
A condom that's too large can slip off. A condom that's too small can break or be uncomfortable. The right size ensures both safety and pleasure.
