Determine the Right Condom Size in 4 Easy Steps
With the right condom size, sex isn't just much more fun—you're also much better protected against unwanted pregnancies and sexually transmitted diseases.
Plus, condoms in the perfect size are quicker and easier to unroll.
To help you find the right condom size for you, below you’ll find various guides on how to measure, a chart with all common condom sizes, and lots of other helpful information.
Why the Right Condom Size Is So Important
Imagine trying to run a marathon in clown shoes. Doesn’t sound like a particularly good idea, does it? The same principle applies to condoms.
If you use condoms that are too large, you’ll have the problem that the condom slips off easily, increasing the risk of unintended pregnancies. Additionally, a condom that’s too large will offer little protection against sexually transmitted infections.
If you use a condom that’s too small, you’ll have trouble rolling it on, and it will feel very uncomfortable. You’ll also feel less sensation and might even lose your erection more easily because blood flow is restricted.
That’s why it’s so important to choose the right condom size—it’s the only way to ensure that you and your partner are optimally protected against STDs and pregnancy.
Calculating Condom Size—What Size Do I Need?
Finding the right condom size for you is easier and faster than you might think. Besides an erection, all you need is a tool to measure the circumference or diameter of your penis.
This can be a measuring tape, a ruler, a set square, a folding ruler, or even a special tool like the Condom Sizer.
By the way, the length of your penis doesn’t matter when choosing the perfect condom size. As long as the condom is the right width, you’re safe.
Below, you’ll find instructions on how to determine your condom size using each of these tools.
Measuring Condom Size with a Measuring Tape
To measure the correct condom size with a measuring tape, follow these steps:
- Achieve and maintain an erection
- Find the thickest part of the shaft (the part between the testicles and the glans) of your penis
- Wrap the measuring tape around this spot until it fits snugly
- Read the circumference on the measuring tape
Once you’ve determined the circumference of your penis, you can check the table below to see which condom size is right for you.
How to Find Your Condom Size Using a Ruler
To determine your condom size using a ruler, do the following:
- Achieve and maintain an erection
- Find the thickest part of your penis shaft (the part between the testicles and the glans)
- Place the ruler against this spot underneath your penis (with 0 at the outer end)
- Read the diameter of your penis from the ruler
Once you’ve finished measuring, you can check the table below to see which condom size is right for you. Alternatively, you can convert the diameter to penis circumference using the following formula.
Formula for calculating condom size
If you know the diameter of your penis, you can use this simple formula to calculate the penis circumference and thus the condom size:
Penis diameter (penis width) in cm × 3.14 = Penis circumference in cm
Example: If your penis has a diameter of 3.6 cm, multiplying that by 3.14 gives you a girth of 11.3 cm, which corresponds to a condom size of 53.
Determine your condom size with the Condom Sizer
A measuring device like the Condom Sizer makes it even easier for you to choose the right condom size.
- Achieving and maintaining an erection
- Find the thickest part of the shaft (the part between the testicles and the glans) of your penis
- Place the Condom Sizer at this point and slide it on
- Read the condom size
There’s no easier way to find the right condom size without a measuring tape or ruler.
Condom Size Chart—Finding the Right Size
If you know the diameter or circumference of your penis, you can quickly look up the correct condom size in this chart and find out which one you need:
For Penis Circumference | For Penis Diameter | |
less than 10 cm | less than 3.18 cm | |
10 – 10.5 cm | 3.18–3.34 cm | |
10.5–12 cm | 3.34 – 3.82 cm | |
12.0 – 13.5 cm | 3.82 – 4.3 cm | |
13.5 – 14.5 cm | 4.3 – 4.62 cm | |
14.5 – 15.5 cm | 4.62 – 4.93 cm | |
greater than 15.5 cm | greater than 4.93 cm |
Other condom sizes
In addition to our 7 condom sizes ranging from 47 to 69, other manufacturers also offer additional sizes such as sizes 52, 54, 55, or 56 in the mid-range, as well as extra-small condoms in size 45 or extra-large condoms in size 72. However, as you can see from the table above based on penis diameter, the increments within our 7 sizes are already very fine, and additional sizes offer no significant advantages beyond higher production costs—and thus higher prices for the condoms. It’s similar with shoes—it’s as if there were two additional sizes between sizes 44 and 45, since the difference between shoe sizes is several millimeters, not just 1 to 2 millimeters. Furthermore, unlike shoes, condoms are always somewhat stretchy due to being made of latex, without being too tight.

As an alternative to the chart, you can also find your condom size using a condom size calculator.

How to tell if you’ve found the right condom size
Once you’ve ordered condoms in the right size, you can try them on to see if they fit you properly.
You’ll know you have the right condom size if the condom unrolls easily. It fits snugly on your penis and wraps around it like a second skin, without feeling uncomfortable.
You’ll know you have the wrong condom size if the condom is hard to unroll, if it slips or pinches, and if it just feels uncomfortable and unsafe overall.
Average Condom Size in Germany—What’s the Normal Size?
Most men in Germany use condom sizes 52 or 53 for contraception.
However, if you’re smaller or larger than this size, it doesn’t automatically mean you’re abnormal. Having a larger penis isn’t automatically better than having a smaller one, either.
Which size is “the right one” always depends on what your partner prefers and how much space they have.
