The average penis size is seven to 10cm in length and nine to 10cm circumference when flaccidDr Flo,Is it possible medically for a man to increase the size of his penis without any side effects? JamesDear James,The average penis size is seven to 10cm in length and nine to 10cm circumference when flaccid and 12 to 16cm length and 12cm circumference when erect. Many people who feel they have a small penis usually have a size that is within the normal range. Increasing the size is only recommended for those with a flaccid penis of less than 4cm length or an erect penis of less than 7.5cm length. The only medical ways of enlarging the penis size is through surgery, use of prosthetic or vacuum devices, which should be done by a urologist.
