I feel like youre probably asking about length, so i feel like 7 is big to me by all accounts.

Grith however i feel like is way more important when i think about size. 7 long and 4 around feels like nothing to me. When i buy toys for myself id never buy less than 5. My partner is 5.5 at base 6 around the head and hes my glass slipper. Any more and id die ahah. Im really petite for reference.

But yes to the point, when I saw OP's measurements my first thought was "well his grith is a little low" and that's kinda why im chiming in and saying I agree. 6 inches of length is pretty average but can be big with a thick shaft. But as someone who takes the dicks im 1000% more likely to not hook up based on grith vs length.
