Hat Sizing
Please don't tell me your "Hat Size".
I can get a much more accurate sizing of my own from your head measurements.
To determine your head measurements, get a tape measure and put it around your head. Place it where you want your hat to rest.
If you have a hat that fits well, put it on. Look and feel where it rests. Measure in that same spot.
Usually, that is just above the center of the forehead in front, and on the upslope of the “lump” in back.
Check the tape to make sure it’s more or less level all around. Pull the tape snug and see if it feels right. If not, try a little higher and a little lower until it feels just right.
Once you’ve found your spot, measure to the nearest one-eighth inch, or one-fourth centimeter.
You may want to use a piece of tape to hold the band to that size, then take it off and put it on a couple of times to see if that’s the right size for you.
