Condoms come in different shapes, sizes, and fits. Some are tapered, some have ribs, some are more snug or slim, and others are designed for larger girths. Which condom you choose affects how it feels, performs, and protects. There’s no such thing as a one-size-fits all condom. To get the most from your condom, choose one that fits well and feels great.
Why Condom Fit Matters: It’s about Protection & Pleasure
Since you use a condom for safety and protection, you want the right size and fit to make sure it can do the job. Condoms that do not fit properly can be uncomfortable and less-effective at preventing STI’s and pregnancy.
Poorly fitting condoms break more easily, slip off, or get removed during sex, which can allow sperm and germs to exchange.
Signs your condom doesn’t fit include:
- “Not feeling anything” or reduced pleasure for the wearer
- Reduced pleasure for the partner
- Difficulty achieving orgasm
- Difficulty maintaining erection
- Condom slipping off (too loose)
- Condom breaking or tearing
- Condom bunching up at the base or hanging off the tip (too long)
- Condom tourniquet (band at the base is too tight)
- Condom not reaching the end of penis shaft (too short)
- Foreskin drag (condom caught in foreskin and dragged up the shaft)
The length of a condom is important, but not as important as the girth when you’re trying to get the best fit. A condom doesn’t have to unroll fully by the time it reaches the base. Some men even prefer having a bit of extra rolled condom at the base, which can function as a penis ring to sustain erection.
But if you run out of unrolled condom before you reach the base of your penis, you need a longer length. Trojan offers a wide variety of shapes, sizes and styles so you can find a condom that fits your size and preference.
Choosing the Right Condom Size
Many people wonder if Trojan condoms fit all sizes. No condom is one size fits all, but since they are made of very stretchy material, a condom can fit a variety of sizes – up to a point. Knowing your measurements and choosing a condom that is sized closest to you will help you get the best fit and prevent condom complaints such as feeling too tight or slipping off.
According to the Boston Medical Group’s analysis of 20 studies of penis size, the average penis length in the United States is 5.57 inches erect and the average erect girth is 4.81 inches. Most standard condoms are designed to fit these averages, plus or minus some leeway. Condoms come in different sizes to accommodate for differences in how you’re built. Some condoms are on the snugger or shorter side and others are wider and longer, such as Trojan’s Magnum products.
What Condom Size Do I Need?
Knowing how to tell if a condom fits or doesn’t fit you is important to get the most out of using one. No two guys are built the same, and there are also preferences for fit to consider.
To know which condom will likely fit you best, convert your girth measurements into flat widths or vice versa. Condom packages tend to list their length and their “nominal width,” which is the measure across the condom when rolled into a circle, or its diameter. If your package doesn’t give the nominal width, refer to the charts below.
Although there is no absolute rule for who should use the different condom sizes, the following guidelines from Medical News Today are based on research and statistics:
- a girth of less than 4.7″ may need a more slim or snug fit condom (2” nominal width or lower)
- a girth of 4.7–5.1″ probably needs a regular fit condom (2”-2.2” nominal width)
- a girth of 5.1–6″ may need a larger fit condom (2.2” nominal width or greater)
- a length longer than 8” may need an extra-large condom
Remember that some condoms are tapered and are narrower at the base than they are along the shaft. Don’t know your measurements? Read on!
How to Know What Size Condom Fits You: Start with Your Measurements
To know what size condom will fit you, start with some measurements. Yes, it’s time to pull out that tape measure, preferably a flexible one used by tailors or fashion designers. If you don’t have a flexible tape measure, you can use a piece of string and a ruler. You need something that will go around your penis to measure its circumference.
When you’re measuring to get your pants size, you need your waist and inseam. Similarly, to get your condom size, you need to know both length and how big you are around. When figuring out what size condom will fit you, measure the girth or circumference of your penis at the base and mid-shaft and measure the length of your penis from base to tip. Both of these measurements are important to find the condom that fits most correctly.
You’ll need to get fully erect to take your measurements. For length, put the end of the tape measure or string against your stomach at the base of the penis, and measure out to the farthest point of the tip. It’s best to put the measuring tape or string along the top of the penis. If you’re using yarn, string, or ribbon, mark or cut the string at the point where it reaches the end of the penis, then measure the length of the marked string with a ruler. Measure to the nearest millimeter or 1/4”.
If you have the Measure app on your phone, you can also use your phone’s camera to mark the points at the base of the penis and the tip, and let the app calculate the length. There’s no need to take a pic and send it to anyone, though!
Now you’ll need to measure your penis’s circumference, or girth. This measurement is even more important than length when it comes to finding the right size condom to fit you well. Wrap the flexible measuring tape or string around your penis, mark the spot where it meets the end, and record the measurement to the nearest 1/8” or millimeter.
You’ll need to measure around your penis in two places: at the base, and at the widest part of the shaft.
Base circumference: Measure around your erect penis at about the base of the shaft. Be as precise as possible as small differences in circumference can affect fit, protection, and pleasure.
Mid-shaft circumference: Measure around your erect penis at the widest part. This measurement may or may not be different – don’t worry either way.
If your penis is roughly the same circumference from base to head, you may prefer a straight or classic fit condom. If your penis gets wider, you may prefer a flared/tapered fit or a bulbous condom shape. These last two shapes provide more room at the head.
However, all condoms are quite stretchy, so there is a degree of personal preference involved. A condom that is too tight can interfere with performance and pleasure, and a condom that is too loose is at risk of slipping off and also not feeling as good as possible. Go with the fit that feels best for you without too much constriction or looseness.
