    How to read a hat sizing chart

    Hat sizes are often measured in one of three ways:

    The imperial system is used to measure head diameter in inches, which normally ranges between 6.5 and 8.

    North Americans use the imperial system, although their sizes are an eighth of an inch larger.

    European/Metric: Uses the metric system to measure head circumference in centimetres, which normally range from 53 to 65.

    At Lock & Co., hat sizes range from small/55 cm to xx-large/64 cm.

    How do you determine a women's hat size?
    What is the average hat size for women?
    How do I size men's hats?
