A penile size of 20 centimeters or 7.8 inches is considered abnormally long, and therefore, is the threshold for what is considered big for a PP.
According to the reference material, the average penile size for adult men falls within a range of 12.5 centimeters (4.9 inches) to 19.1 centimeters (7.5 inches). Any size above this range is then considered outside the norm.
| Size Category | Length (cm) | Length (inches) |
|---|---|---|
| Abnormally Small | < 7 | < 2.7 |
| Normal Range | 12.5 - 19.1 | 4.9 - 7.5 |
| Abnormally Large | >= 20 | >= 7.8 |
Therefore, a PP measuring 20 centimeters (7.8 inches) or more is considered to be abnormally long or "big".
