Condom Size Calculator
Finding the right condom size is crucial for both safety and pleasure. A condom that's too tight can be uncomfortable, restrict blood flow, and be more prone to breaking. One that's too loose can slip off, leading to unwanted pregnancies or STIs. This calculator helps you determine a recommended condom size based on your measurements.
How to Measure for Condom Size:
- Girth (Circumference): This is the most important measurement for condom fit.
- Measure when fully erect.
- Use a flexible measuring tape or a piece of string and a ruler.
- Wrap the tape/string around the thickest part of the shaft.
- Note the measurement in millimeters (mm) or inches.
- Length: While less critical than girth, length can affect comfort.
- Measure when fully erect.
- Place a ruler at the base of the penis (where it meets the pubic bone) and measure to the tip.
- Note the measurement in millimeters (mm) or inches.
Once you have your measurements, enter them into the calculator below.
Understanding Condom Nominal Width
When you look at condom packaging, you'll often see a "nominal width" listed, usually in millimeters (mm). This isn't the circumference of the condom, but rather the width of the condom when it's laid flat. Essentially, it's half of the condom's circumference. So, if a condom has a nominal width of 56mm, it's designed for a penis with a circumference of approximately 112mm (56mm x 2).
Our calculator provides a recommended nominal width based on your girth measurement, helping you match it to products on the market.
Why Fit Matters
- Safety: A well-fitting condom is less likely to break or slip off, providing better protection against STIs and unintended pregnancies.
- Comfort: A condom that's too tight can be painful, reduce sensation, and even cause irritation. One that's too loose can feel baggy and distracting.
- Pleasure: When a condom fits correctly, it allows for better sensation and a more enjoyable experience for both partners.
Remember that condom sizes can vary slightly between brands. This calculator provides a general recommendation, but trying a few different sizes and brands might be necessary to find your perfect fit.
