I'm not sure why people are only giving one measurement when the size was asked for, not specifically the length or girth.
6.75x5.25?
I would've said 7" length, but the tightness of the grip combined with the darker red colouration of the penis head and preceding area suggests to me that it's a little more engorged than it would naturally be. Girth looks pretty standard, again possibly slightly thicker than normal towards the head for the same reason.
