Condom Sizing

The Importance and How-To of Condom Sizing

If you don’t pay attention to condom size, the little rubber can be rendered useless and result in the spread of infection or pregnancy. Slippage during use is very common because many guys are putting on the wrong size.  A condom should fit snug and stay in place- but of course, not so sung that it is painful!  Condom size varies from brand to brand and also from texture to shape, so it also pays to test as many as you can over a period of time before you settle on one specific condom (if ever!).

How do you work out condom sizing?

The first thing you need to work out is your penis size. From there you have a definite size guideline to buy condoms and you reduce the risk of wasting money.

How do I measure my penis?

Measuring your penis is easy but you have to do it right.  You need either a soft measuring tape or a piece of string and a ruler to measure the string against. First you need to measure the length of your ERECT penis. Put the measuring tape or string at the very base of your penis and measure up to the very tip making sure it’s central and straight. Jot that length down.

Then you need the circumference. This is very important as done by measuring all the way around your penis at the mid-point of the shaft. At this stage, you could also measure the circumference at the head (the widest part).

Condom Size Guidelines

Now to get the correct size you can follow these general guidelines. To understand what condom width fits, divide your penis circumference by 2.25. How did we get this number? This post explains our formula and research.

According to a recent study by the Kinsey Institute, most male condoms in North America are made to fit the “average” guy who measures 5.57″ long and 4.8″ girth. Thus, size “regular” condoms tend to be 7.5″ long and 2.0-2.2 base width. Base width is the condom lying flat.  It is not the circumference.

Generally, if you measure less than 4.8 inches in girth, go with snugger fit condoms.  If you are thicker than 5.2 inches go with larger condoms.  For more suggestions and details, for example on shape and material, go to our post titled What Condom Size Am I? (can you tell we get this question a lot?).

You can also head over to our Condom Calculator and view the dimensions of over 100 condoms.  We also have an ill-fitting solutions chart that offers suggestions to specific condom fit problems. Finally, for guidelines converting penis girth to proper condom width, view the table in this post.
