Yeah, that's bigger than average. There is bigger out there for sure, but you're still considered "big" by most peoples standards. I am just about the same girth as you but not much more than 6" long, so I'd be considered average due to my length.
As with any penis size dimension, I've noticed a lot of guys (especially on this site) bullshit about their girth more than anything. That's why you get guys here claiming they're 8"x6" and other guys claiming they're 8"x5.25-5 yet they look the same. 1/2 to 3/4 of an inch doesn't seem like much of a difference but it is when it comes to girth. Lookswise, a half inch of girth is comparable to a full inch of length, in my opinion, and an inch of it basically seperates sizes into groups (4" tiny, 5" small, 6" average, 7" big, 8" huge).
So basically, if you measured properly, you're "biggish" from an unbiased, bigger (no pun intended) picture, the same way a 6'1 foot tall man is "tallish" although there are taller guys out there (although not a whole lot).
Be happy. I think your size is ideal and respectable, from my eyes. With the height analogy thing, I'd place myself to be 5'11.
