How do I know what condom size I need?

Measure the circumference at the thickest point when erect, then match it to the brand's size chart. Brands like MY SIZE convert that measurement into a nominal width in millimetres printed on the pack.

What does nominal width mean on a condom box?

Nominal width is the width of the condom laid flat, measured in millimetres. It is not the same as your girth, so always check the brand's chart rather than comparing the numbers directly.

Are XL condoms longer or just wider?

XL condoms are mainly wider, with more room at the base and head. Some are slightly longer too, but length is rarely the problem since most condoms are longer than needed.

What happens if a condom is too big?

A condom that is too big can slip off or bunch up during use. If that happens regularly, try a standard or small size, or a brand with millimetre sizing so you can go down one step.

Can a condom that is too tight break more easily?

Yes, a tight condom puts extra strain on the material and is more likely to tear. It can also feel uncomfortable and dull sensation, so a roomier size is often the better choice.
