Is my penis the right size and shape?

Every man's penis is different, and penises can vary in size and shape.

What's the average penis size?

The average penis length is:

  • about 5-10cm (2.5 to 4 inches) when limp
  • about 12-19cm (5 to 7 inches) when erect (hard)

Penises that are smaller when they're limp grow more when they're erect, so your penis' size when limp does not necessarily predict its size when erect.

Many men worry that their penis is too small. But when you look at your penis from above, it seems smaller than it is because you're looking down on it. If you're overweight, your penis may look smaller as some of its base will be hidden by fat around your stomach.

The size of your penis can also be affected by other things. For example, if you're feeling cold or anxious, it can make your penis temporarily smaller.

Does penis size affect sexual performance?

Some people believe that men with larger penises are more capable of satisfying their partners sexually. However, this is not true. Many factors such as understanding and responding to your partner's needs and wishes are more important for a fulfilling sex life than the size of any body part.

Is it normal to have a curved penis?

It's common for the penis to curve slightly upwards or to the left or right when it's erect.

However, if a bend in your penis is causing you problems, such as pain during sex, or you feel any abnormal lumps in your penis, see your GP or go to a local sexual health or genitourinary medicine (GUM) clinic.
