If you've never used a Cowboy Hat before, a slightly less accurate, but convenient way to determine your hat size is to grab a snapback hat, and map your most comfortable fit to the chart. As with the above technique, if your measurement falls between sizes, order a size up. You can always add a bit of padding in the sweatband to achieve the perfect fit.
