Measuring your head circumference

Measuring your head circumference: 

For a perfect fit, I will need your head circumference to the closest 1/4". Measure around your head, above your ears, where you like to wear your hat. Go around the widest part of your head. Don't pull the tape too tight. Measure a few times to obtain a consistent size. And please don't add to your measurement.  If you don't have a cloth measuring tape, you can use a ribbon or string to measure and then compare to a yardstick/tape measure/ruler etc.
