What Is This Calculator About?
This tool matches penis measurements to recommended condom sizes. It focuses on girth, length and a concept called nominal width.
How To Use The Calculator
- Select the preferred unit (inches or centimeters)
- Enter the erect penis length
- Enter the erect penis girth
- Click “Calculate”
- Review the suggested condom size and recommended dimensions
How To Measure Penis Girth
- Use a soft measuring tape
- Wrap it around the thickest part of the erect penis
- Note the measurement
- If a measuring tape is not available, use a string. Mark it, then measure the marked length with a ruler
- Keep the tape snug, but not too tight
How To Measure Penis Length
- Start at the base of the erect penis, where it meets the pelvis
- Measure along the top side until the tip
- Record that number
- The measurement should be as accurate as possible
What Is Nominal Width?
- Nominal width is half the condom’s circumference when laid flat
- It’s used to match a condom’s fit to the penis girth
- For example, a 3.5-inch girth might match a nominal width of 1.75 inches
Extra Tips
- Try a few sizes to find the perfect feel
