When in doubt, have the person measure their noggin and then you can make it to fit them exactly.

Bev's Country Cottage (www.bevscountrycottage.com) has size charts for hats, socks/slippers, sweaters, blankets, and even baby measurements. This is a treasure trove - especially if you like to create your own patterns. The only thing that's missing is an approximate number of stitches to cast on in order to reach the diameter you want. I'm working on capturing that, using average sized yarn (DK/Worsted) and needles (US7-8). Once I have a fairly good list, I'll post it here for download. Or... If anyone already has this, please feel free to put the link to it in our comments section.
I may be hat-girl for a while so I apologize in advance if my crafty pursuits get kind of boring. :) It's winter and hats seem like a good endeavor.
