Wearing the correct condom size is crucial for using a condom safely and comfortably. Condoms that are too big can slip off and ones that are too tight can break. You don't want to find yourself in either of these situations. If you are complaining about condoms, chances are, you are not using the correct condom size. When it comes to condoms, one size definitely does not fit all. Learn how to figure out your condom size.

Determining Your Condom Size

Because condom sizes are listed by width and length, you will need to measure your erect penis.

  1. Your condom size must be based on the size of your erect penis. For length, use a ruler and press it into your pubic bone as far as you can and measure to the tip. For width (girth), use a piece of string or a soft measuring tape wrapped around the thickest part of the shaft of your erect penis. Mark where the string/tape meets and then measure it exactly.
  2. Once you know your penis length and width, you can use a condom chart that lists the various condom sizes of the different brands.
  3. Choose the condoms that have the size that most closely matches your penis size.
  4. Don't buy condoms based on the size of your non-erect penis. Many factors can cause your penis to temporary shrink 2 inches or more (like cold weather or going swimming). 

Understanding Condom Sizes

Condom width should be used when comparing condom sizes. Your penis girth will affect how a condom fits. If your girth is above average, a standard sized condom might feel too tight. If your penis girth is less than average, standard size condoms may slip off during sex. Use these general guides:

  • Standard condoms have a width of 1.75 to 2 inches (44.45 to 50.8 mm)
  • Snug condoms have a width of under 1.75 inches
  • Large condoms have a width over 2 inches

Condom length may be confusing because different condom manufacturers use slightly different measurements. This means that what one manufacturer may describe as a large condom may actually be a standard size condom for another. You can use the following as a general guide:

  • Standard condoms usually have a length between 7.25 to 7.8 inches (184.15 to 198.12 mm)
  • Snug condoms may have a length of 7 to 7.8 (177.8 to 198.12 mm)
  • Large condoms length ranges from 7.25 to 8.1 inches (184.15 to 205.74 mm).

Choosing the Correct Condom Size

Once you figure out the condom brands that come in your condom size, you may need to do some experimenting to see which ones give you the best mix of fit, comfort, and sensitivity. Keep in mind that a condom should completely cover your penis and have some space at the tip to catch the ejaculate.

Part of this experimenting may be trying condoms that are made from different materials such as latex condoms, polyurethane condoms, polyisoprene condoms, and lambskin condoms.

Certain condom brands (like Trojan Double Ecstasy Condoms and LifeStyles Turbo Condoms, for example) use special lubricants to heighten sensitivity and pleasure. If these brands match your condom size, it may be helpful to give them a try. There are also condoms that have different textures and shapes. With the variety of condom sizes available, don't limit yourself.

Finally, never underestimate the power of a good lubricant. Lubricants like Astroglide, Wet Gellee, and Wet Naturals Beautifully Bare can add a silky touch to your condom and make it feel more comfortable. Silicone-based lubricants usually stay slippery longer. Adding some lubrication to your correctly sized condom may offer that special sensation to make for an extra enjoyable condom experience.
