Penile size differs between men of different ethnic backgrounds and large studies of penis girth and length have been conducted by condom manufacturers. What many men perceive as a short penis actually falls into normal range size. Based on many published charts, scientific articles, and self reported web based surveys, 95 % of Caucasian men will fall into one of the following categories of size:
- Average length of flaccid penis is between 3.4 inches and 3.7 inches (8.6 cm and 9.3 cm)
- Average length of erect penis is between 5.1 inches and 5.7 inches (12.9 cm and 14.5 cm)
- Average circumference of an erect penis is between 3.5 inches and 3.9 inches (8.8 cm and 10.0 cm)
Penis size is an important issue for many men and men of all ages are concerned about length and thickness of their penises. As with any health concern, men who are worried about their penis size should consult with a urologist trained in sexual medicine.
