This debate on penis size may never be answered. The results of several studies seem to indicate that the average erect penis length is between 5.1 inches and 5.9 inches in length. So, anything longer than that can probably be considered big.
Literature around the average girth or circumference seems to flip-flop, but several studies have described an average mid-shaft circumference to be 4.49 inches and 4.97 inches when fully erect.
Any measurements that you take should be done when your penis is erect, as that’s all that matters when you’re pleasing a woman. To measure your penis length, simply measure from the base of the penis to tip of the penis with a ruler. Make sure, however, that you don’t measure from the underside; the base you should measure from is on the topside of your penis. For circumference or girth, take a piece of string and wrap it around the mid-shaft (halfway up the length of the shaft), then transfer the string to a ruler.
