Our order form is already calibrated to place orders if you know your US Hat size. If you have not ordered a hat before or need to convert Metric Hat Sizes to US Hat Size, please see the table below before ordering.
Measure the widest part of your head with a tape measure. Place the tape measure a finger width above the ear and bring it across the mid forehead, completely circling the head. Note the measurement and reference the chart below for your hat size. If your measurement falls between sizes, round up to the next largest size.
