Like bodies, penises come in all different shapes, sizes, and colors. The size of your penis is determined by genetic traits that you’ve inherited from your parents – just like your eye color and your height. So there’s no “normal” size, because everyone is different. Studies have shown that the average penis size ranges from 2-4 inches without an erection, and between 5-6 inches with an erection.
If you have serious concerns about the size of your penis or you’re late going through puberty, talk with your health care provider.
