    I'm just wondering how much your cock grows from flaccid to erect. I know that smaller penises grow more percentage than large, but nothing is certain, you know...

    To calculate the percentage, you divide erect length with flaccid length and then do the same with circumference. And then you put those two percentages together and find the average.

    For example:
    Flaccid: 4,9 in long and 3,1 in thick
    Erect: 8,9 in long and 6,3 in thick
    8,9 / 4,9 = 180%
    6,3 / 3,1 = 200 %
    Total (180+200 / 2) = 190%

    This number tells you how much your penis grows from flaccid to erect, in my case with 190%, becoming almost twice as big when erect. I read that the average penis grows about 197%, so I'm a bit below, but I am compansating by having a lot above average penis size :tongue:

    I come up with about 220% myself, so I guess this makes me a Grower rather than a Shower.

    It does kinda send it off if you're relatively thick flaccid.

    I go from a circumferance of 4.25" to 5.75"

    Let's say the average flaccid length is about 3
    Average circumferance 3.5

    Average hard - 6
    Hard circ - 5


    the average "increase" is around 170%

    By the way, the above formula for calculation is simple but heavily weighted toward width. This does not reflect volume or perceived size, which is related to visual lines and this probably weighted to length as well. But, it is a fun and easy way of seeing where you stand. :D

    I go from about 1.5 long to 6 long (400%), but from about 4 to 5.5 (130-something) in girth.

    I came up with around 185%, I guess that seems right.

    That figure isn't how much you grow by surely... I think it's more like how the size of your erection compares to your flaccid state. A growth of 200% would be monumental, you're erection would be 3 times the size of your flop-on. But then I think i'm nit-picking about the wording you used. Or maybe I'm wrong.


    Anyway I'm 5 inches on the flop and just about 8 inches hard, so that makes....

    160%

    Circumference... I don't have a very accurate method for measuring but about... 4.5 soft and 5.5 hard, which is....

    122.2222%

    And now I add them together and take the average aye?

    282% divided by 2 makes....141%

    Now for a bit extra maths I think if you minus the 100% which is your penis size in a flaccid state (i think) you can find the approximate percentage of added "size" from an erection which would be 41%.

    Sounds about right to me.
