How to Correctly Measure Your Penis to Find the Perfect Condom Size!

Does your condom really fit you? Learn how to correctly measure your penis to find the perfect condom size!


If you feel as though condoms aren’t for you due to comfort reasons or because they seem to strangle you or fall off at the exact wrong time, never fear. It’s all a matter of getting the proper condom size.

After all, it’s not the condom’s fault for being the right size for someone else, but not for you. Just imagine buying one-size-fits-all jeans or sneakers. What are the odds that they’ll fit you properly? Super slim, my friend. To find a condom that fits the right way, all you need to do is learn how to correctly measure your penis and you’ll get the perfect fitting condom, every time!

Different Condom Sizes


The major reason people assume all condoms will fit them, even when they are the wrong size, is due to their extremely stretchy nature. But, just because something stretches, this doesn’t mean that it will fit everyone the same way. Condoms which are too small for you are much more likely to break because they are stretched beyond their capacity. On the flip side of this coin, if the condom is too big it is likely to fall or slip off. This could possibly expose you to an STD or allow your semen to slip past the goalie.

If you are new to using condoms, my advice is to begin with a regular sized one and then move up or down in size accordingly, one step at a time. You can consult our condom size chart for measurement information.  If you are a visual learner we have a neat info-graphic available as well. There is no reason to buy a huge box of ill fitting condoms, when you can simply buy a smaller amount and waste none. And, it’s not just a comfort thing. It’s all about effectiveness and protection as well.

Measurement breakdown of different condom sizes:

• Small- 1.9″ wide x 6.3″ long
• Regular- 2.0″ wide x 7.9″ long
• Large- 2.1″ wide x 7.9″ long
• Extra-Large- 2.3″ wide x 8.1″ long

The head size of the condom is also particularly important for comfort, because the head of the penis (especially the underside) contains the most concentrated amount of nerve endings. The head size can vary greatly depending on the style and brand of the condom you choose. Some, like the Trojan Her Pleasure Ecstasy have a balloon-ish shaped tip which allows for the maximum amount of head freedom, while others like the Crown Skinless Skin have a more streamlined and tightly fitting shape. Different brands also make condoms in various thicknesses such as the Kimono MicroThin which is 0.0019” thick, versus the Beyond Seven Aloe which is 0.0024″ thick. The thickness or thinness of a condom will greatly change the amount of stretch in the condom.

How to Measure Your Penis to Find the Perfect Condom Size:

Even though most guys have measured their penis at least once in their lives out of curiosity or bragging rights, the chances are it was not a precise measurement. Taking a minute or two to get an accurate measurement is totally worth it, as it could increase your level of pleasure and protection for years to come.

Before we get started on your penis measurement process, there is an important note about your penis length measurement versus the length measurement of a condom. Please take the reservoir tip and space for ejaculate into consideration when choosing the length of condom you’d like to purchase.

Follow these 5 easy steps and you will have a much better chance of finding your perfect fit! Happy measuring!

Measurement Materials Needed:

  • Pen
  • Paper
  • Soft Measuring Tape (like the ones a tailor uses)
  • String and a Ruler (only needed if you don’t have a soft measuring tape)


  1. Gather your materials.
  2. While fully erect, position the measuring tape or piece of string at the base of your shaft, where it meets your pubic bone.
  3. Measure all the way to the end of the tip and use the pen to mark this spot on the tape or string.
  4. Without squeezing the shaft with the tape or string, gently wrap the penis once around for a girth measurement, approximately 1/4” away from the body. Start the wrap on the underside, so it is easier to mark the tape or string when it reaches the top.
  5. If using string, lay it out taught on a flat surface and compare the two marks with a ruler to find your exact measurement.

Now that you have found your perfect condom size, it’s time to learn how to use a condom.
