All right, this is how it should be done. A quick googling gave me this pic which is essentially as good as it gets: neutral enough camera angle, hand crossing the top of the cock and not placed at either end.

So the cock along the green line is 433 pixels, the hand 173.
I placed my hand in the exact same position on a graduated cardboard roll, and looked how wide it was at that same point, with one eye closed. I did the measurement two times a few minutes apart, I got 96 and 95mm, so let's keep 95.5.
My hand breadth is 91mm, the average female's is 74mm.
So, assuming she's got average hands, her hand would be 95.5*74/91=77.7mm
Hence the cock would be 433/173*77.7=194.5mm (7.66")
FWIW.
What's the margin of error when y'all do the estimates in this fashion?
