Sizing Hat

To find your hat size, you’ll need a soft, flexible tape measure or a piece of string and a ruler. If you’re using a tape measure, wrap it around the back of your head about one-eighth of an inch above the top of your ears. Allow the two ends to meet in the center of your forehead above your eyes. Don’t pull the tape tightly; it should rest gently against your skin. Release the tape while keeping your finger on the point opposite from the free end to mark your head circumference measurement. Record the measurement, and round it to up the nearest eighth of an inch; match this number to the hat sizing guides below. If you’re using a piece of string, simply wrap it around your head until it meets in the middle of your forehead, cut off the excess, and measure the remaining string with a ruler to get your head size. Always measure at least twice to be sure that you’re getting the most accurate results possible.

MEASURING WOES: WHEN ONE SIZE DOESN’T FIT ALL

Several factors can throw you off course when you’re trying to measure your head for a new hat, but you may not encounter them until you try on a few of your favorites. Standard measurements may vary among manufacturers. For example, a medium-sized trilby hat made by one company may be slightly larger or smaller than a similar hat offered by a different brand. Some materials tend to create a looser or tighter fit than others. It’s important to remember that sizing charts are approximate.
