Penis girth also affects how a condom fits. The average penis girth (circumference) is 4.5 to 5 inches. If your girth is above average, a standard sized condom might feel uncomfortably tight and the larger sized condoms could be appropriate for you. For readers whose penis length or girth is less than average, it's important to note that standard condoms could simply fall off during sex. Snug fit condoms, which are a bit, well, snugger, are a good option for these fellows.
Condom manufacturers may have once catered only to "average" size men; however, these days condoms come in many shapes and sizes. Here is a chart that gives some common measurements for different size condoms:
Length of condom (inches)
7 to 7.8 Snug
7.25 to 7.8 Standard
7.25 to 8.1 Larger
Diameter of condom (inches)
1.75 to 2 Standard
2 to 2.25 Larger
As you can see, a condom that is called "large" may in fact have the same dimensions as another brand's standard-fit. Different condom manufactures use slightly different measurements and have a number of shapes available, so you may want to try a few condoms on for size to which is most comfortable. Custom-made condoms do exist and are available on the internet, by mail, or at a sexuality specialty shop. Check out this Condom Wizard to learn about condom shapes, sizes, textures and more.
To find out "how big is big" or where you fall along the penis size continuum, you can measure your erect penis to know for sure. Or for even more fun, have a partner do it! Measure your length from the tip of the head along the upper side of the shaft to the point where the penis joins the body. For girth, measure the penis circumference at the widest point using a tape measure or a piece of string. As you probably are aware, condoms are the best way to prevent against STIs as well as a reliable pregnancy prevention method. No matter the size of your penis you should be able to find a condom that fits you well, that will keep you and your partner protected, and allow all the pleasures of sex to thrive! Enjoy and good luck.
