Condomerie's Measurement System for Condoms

About CAS-index

Explanation of measure points CAS Index

Most condoms come under category CAS 4 / 4. The circumference of condoms in this category can be used as an average size. If you want to try a snugger fit, CAS 3 or smaller might be a good choice. If you're looking for a wider condom, try CAS 5 or larger.

To make it easier for you to choose from the many different brands, the Condomerie® has put together special Trial Packs.

Standard size condoms fit most men. But there are slight differences between brands, so that one may be more comfortable for you than another. The Condomerie® also sells condoms for men who need a larger or smaller size. A properly fitting condom is safer, more comfortable and offers better protection against STIs and pregnancy.

Manufacturers use an average size to determine the measurements of their condoms. But this so-called 'average' can vary from manufacturer to manufacturer. So one brand may call a condom of a certain size 'large', and another brand may call a condom with exactly the same measurements 'extra large'. To put an end to all this confusion, the Condomerie® has classified its entire assortment of tested condoms by size in a measurement system: the CAS index (Condomerie Amsterdam Standard index).

 

Condom circumference important element

The most important thing when looking for the best fit is the condom's circumference. A condom that's too large can easily slip off, but a condom that is too tight is uncomfortable and the risk of tearing is greater. The length of the condom isn't as important, but should be as close to the length of the penis as possible. The condom's thickness and elasticity can also make it less or more comfortable.

The Condomerie® determines the circumference of a condom by measuring it in the following places:
A] the opening (important for comfort)
B] approx. (7 cm) from the opening (the measuring point for manufacturers).

Most condoms come under category CAS 4 / 4. The circumference of condoms in this category can be used as an average size. If you want to try a snugger fit, CAS 3 or smaller might be a good choice. If you're looking for a wider condom, try CAS 5 or larger.

The average length of most condoms is CAS E. The average thickness is CAS •••.
