Frequently Asked Questions
How do I measure my condom size?
Measure your erect penis circumference (girth) at the thickest point using a flexible measuring tape. Also measure the length from base to tip. Enter these measurements in the calculator above to find your recommended condom nominal width.
What is condom nominal width?
Nominal width is the width of the condom when laid flat, measured in millimeters. It is the most important measurement for condom fit. Regular condoms are typically 52-53mm, XL condoms are 56-60mm.
What size condom do I need?
It depends on your erect girth. Girth under 11.5cm typically needs regular (52mm). Girth 11.5-13cm needs regular to XL (53-56mm). Girth over 13cm needs XL (56-60mm). Use the calculator above for a personalized recommendation.
What happens if my condom is too small?
A condom that is too tight is more likely to break during use. It can also cause discomfort and reduce sensation. If the condom feels overly tight or difficult to roll on, try a larger size.
What happens if my condom is too big?
A condom that is too large can slip off during intercourse, which defeats its protective purpose. If the condom feels loose or slides easily, try a smaller size.
