omorka | A Matter of Size

Okay, I have several knitted hat patterns here, and some of the sizing is just not making any sense. I have a couple of patterns for which their women's size (or medium) is clearly larger than the men's size (large) for other patterns, and the stretchiness of the knit (or lack thereof) doesn't seem to have anything to do with it.

Flist, if you would please do me a favor, could you:

(a) post your hat size, if you know it (I have enough friends who wear fedoras or panamas that this should be a simple matter of checking inside the crown)

(b) if you don't know it and you have a tape measure around, could you measure your head circumference (parallel to the floor, just above the eyebrows) for me?

I'm a 21 1/4" circumference, which puts me somewhere between a 6 3/4 and a 6 7/8 hat size. I vaguely remember my MOB fedora being a 6 7/8, so that sounds right.
