With the vision of "Excellence in Condoms", our creative team at MISTER SIZE is continuously working to make condoms even better - even more sensual. Our claim: sex with a condom should be as good as without! We are committed to this every day. After almost 20 years of passion and experience with condoms in the right size, we have therefore launched Mister Size. MISTER SIZE is the condom that looks like a condom, that protects like a condom - but that doesn't feel at all like a conventional condom when in use. Why? Because men and women feel almost nothing at all. But it's not just the negligible thickness that is a noticeable pleasure gain: MISTER SIZE comes in seven different sizes - Every man's best piece is, after all, also quite individual.

Here you can measure your condom size easily and conveniently with 3 different methods.


The safety of contraceptive methods is calculated according to the Pearl Index, but no contraceptive is 100% safe. Condoms have a Pearl Index of 2-12, which means that out of 100 women who use condoms for a year, 2 to 12 will become pregnant. In most cases, this high number is due to application errors. You can find out more about correct use in FAQ 18. However, when it comes to protection against STIs such as HIV, syphilis, gonorrhea, hepatitis B and hepatitis C, a condom offers a very high level of protection.


Condoms are rubbery, thin covers and are used during sex to protect against unwanted pregnancy and STDs. They have to be pulled over the erect penis before sexual intercourse and, along with sterilization, are one of the few contraceptives available to men.


Condoms do not actually have any side effects. However, if you have a latex allergy, they can trigger an allergic reaction. About 2% of people suffer from a latex allergy, so they have to use latex-free condoms.

Other side effects such as strangulation, slipping or loss of sensation are reduced or avoided completely if you use a condom of the right size.

Almost half of all couples (48 %) use the pill, the other half (47 %) use condoms. All other contraceptives account for only a small proportion. In some cases, of course, several contraceptives are used in parallel, e.g. condom and pill.

Most men use condoms for contraception. For a condom to really protect you, it is crucial that you know how to use it properly and you use your individual condom size. In addition to protecting against pregnancy, condoms also protect against STIs compared to other contraceptives.

Condoms are subject to the Medical Devices Act and must therefore be certified. This can be recognized by the CE mark on the package. To ensure that the condom is really safe, it should fit perfectly. A condom that is too small could tear more easily, and one that is too large is more likely to slip off.

Yes, every man can use condoms. No matter what penis size and shape, there is a suitable condom, Mister Size, for example, in 7 different sizes from a nominal width of 47 mm to a circumference of 69 mm. In addition, all condoms are stretchable. Erection problems are often due to condoms not fitting. For latex allergy sufferers, there are latex-free condoms, but unfortunately not yet in so many different sizes.

Yes, but you have to be able to pump 18 liters of air into condoms without them bursting. This is stated in the European standard EN ISO 4074. However, it is crucial that you know how to put them on and use them during sexual intercourse.

Yes, because during oral sex semen can enter the body through the mouth and trigger an HIV infection. Particularly thin condoms, such as Mister Size, are also suitable for oral sex.

If the erection decreases when the condom is put on, it is usually because the man is afraid of doing something wrong when putting it on or that the opening of the condom is not as confident as one would like. Young, inexperienced men are particularly affected by this.
It helps to first use condoms on your own and to practise with them and also to use them when masturbating. If you are then familiar with them, you can even include the condom in lovemaking and have your partner put it on.

It happened: The condom has broken. In order to avoid an unwanted pregnancy, there is the option of the "morning-after pill". The morning-after pill is taken a maximum of 48 to 72 hours after the condom accident. However, the intake should be discussed with a gynecologist or pharmacist in any case, as it is important to be medically informed about the effectiveness and side effects.

If condoms have always been too big for you, you can try Mister Size 47 or 49. These condoms have a nominal width of 47 or 49 mm and are therefore smaller than the 52-54 mm ones from the drugstore.

Basically, all water-based lubricants are suitable for use with Mister Size condoms. In addition, you should always check the packaging to see if the manufacturer recommends using it with condoms. Oil-based lubricants, such as silicone oil, should not be used with Mister Size condoms because they attack the latex.

All condoms, whether thin or thick-walled, are subject to the same European standard EN ISO 4074, which states, for example, that you must be able to pump 18 liters of air into a condom without it bursting. This means that thin and thick condoms meet the same safety standards.

  1. Condoms should always be stored in a cool, dry place. Direct exposure to heat makes condoms brittle. It is also important that the sealing film is undamaged and that the best-before date is not exceeded.
  2. When tearing open the sealing film, do not use sharp-edged objects such as teeth or fingernails so that the condom cannot be damaged.
  3. Check in which direction the condom can be unrolled. If it does not unroll, it has been placed on the penis the wrong way round. However, semen may have already reached the condom. Therefore, do not simply turn it over, but use a new condom!
  4. Hold the reservoir with your thumb and forefinger so that there is no air cushion. Pull the foreskin back a little and roll the condom completely over the stiff penis from the reservoir.
  5. And a little tip: always have condoms ready to use nearby so that you can start right away without having to search for them :-)

Yes! Mister Size condoms are vegan. Mister Size condoms contain no animal ingredients or animal by-products, there has been no use of animal ingredients or by-products in the manufacturing and production process, and they are not tested on animals.

In principle, condoms should only be stored at temperatures of up to 30°C over a longer period of time. You should also not store condoms permanently in direct sunlight. However, short-term storage for 3-4 days in extreme heat of up to 40°C, for example during transport by post, in your car or in a packing station, is possible without any problems. So even in summer, you can order your condoms online or take them with you on your travels without any worries.
