Average girth is a little under 5" in just about every study you read. There is also much less variation than in length (probably because the volume is proportional to the length and the square of the girth).
Also you will notice quite small differences. A 5'9" man is average height, a 6'3" man is very tall, but that's only 10%. A 5.5" girth will look big, at only 10% above average.
By the time you get to 6" most women will be reaching for the lube.
Nerves of steel, knob of butter, pinch of salt.
