To measure the penis accurately, follow these steps:
- Ensure the penis is fully erect for the most accurate measurement.
- Use a ruler or a flexible measuring tape.
- Measure length by placing the ruler or tape at the base of the penis on the top side, pressing gently against the pubic bone to bypass any fat or pubic hair, and measure in a straight line to the tip of the penis.
- To measure girth (circumference), wrap a flexible tape measure around the thickest part of the erect penis shaft and note the measurement where the tape meets.
- For width, you can calculate it by dividing the girth by approximately 3.14.
This method is the standard used by medical researchers as it provides a consistent and reliable measurement with a clear stopping point at the pubic bone. The average erect penis length is about 5.16 inches, and the average girth is about 4.59 inches.
