The ‘average’ length of an erect adult penis is about 5.5″ – 6″.

It’s worth remembering that the average adult penis is ‘designed’ to fit the average depth of the adult vagina which is also about 6″.

There is no normal or average size for a soft/flaccid penis because they vary enormously. Some guys ‘shrink’ a lot more than others when soft. You can NEVER judge how big a guy will be when he is erect from his soft penis size.

The ‘average’ girth of an erect adult penis, that is the distance AROUND the penis measured at the thickest point, is about 5″. Anywhere between 4.7” and 5.2” is normal.

Most penis growth happens between the ages of 12 and 16 with a subsequent slower rate of growth until the age of 17 or 18. Sometimes up till about 24 or 25yo.

Approximate lengths for under 18’s are:
At the beginning of puberty 2.4”
12 to 13 ……. 3.0″ to 4.0”
14 to 15 ……. 4.0″ to 5.0”
16 to 17 ……. 5.0″ to 6.0”

To convert to cm, just multiply the number in inches by 2.54cm. For example, 5 X 2.54 = 12.7 So a 5″ penis is 12.7cm
