Average size of erections

posted in Sex Advice |

We’ve talked about the length of the penis in its ordinary non-erect state, but how long should it be when it’s erect?

Interestingly, most penises are very much the same size when erect.

  • The man whose non-erect penis is smallish will usually achieve about a 100 per cent increase in length during sexual excitement.
  • The man whose non-erect penis is on the largish size will probably manage about a 75 per cent increase.
  • This means the great majority of penises measure between 15cm and 18cm (6-7 inches) when erect, with the average figure being about 16.5cm (6.5 inches).

So you can see that even if a man has got a ’small’ penis, he’s got a built-in compensating factor that will bring him up to about the same size as the guy who appears to be ‘better equipped’ in the shower room.
