I would say any penis properly and honestly measured even bone pressed over 12" long is "large". Prolly 9" flaccid honestly measured.
Personally, I like to believe that anything over 7 counts or I will have to resign. I'd keep my medical LPSG medical benefits though wouldn't I?
I'd say anything over 7 is large, and average does fit in the 5-6 zone. I don't belong in either, I'm somewhere near 7, but just no there. I'm okay with being a bit above average. But we seriously need to take girth into consideration. That, sadly, isn't a good word for me.
