How to Measuring Your Head for A hat
There are two primary methods of measuring your hat size. Choosing the perfect hat size should be based on the style in which you wear your hat. Determine hat size by using a flexible tape measure, a string, and a ruler. You will need to take both measurements and then use the larger measurements to determine your hat size.

Step 1 Measure Your Head Circumference
Take a soft measuring tape or a string, and wrap it around above the ears and across your eyebrows. Make sure the tape measure is straight and not twisted. Please stick your finger under the tape, so there is a little space, and there you have the head circumference. If you get between measurements, you should choose the larger size or adjust your hat accordingly. If you used a string, match it to a measuring tape.
