Finding the proper fit for your head is crucial because hats come in various styles and dimensions. Finding the appropriate hat size can be difficult, especially when purchasing anything online when you cannot try it on ahead of time.
How do you calculate your hat size?
To discover your hat size, measure the circumference of your head and use one of the hat size charts. Be careful! American heights are usually greater than British ones.
- Range of international sizes: XS-S-M-L-XL-XXL-XXXL;
- Range of American sizes: 6 1/2 – 8 1/8; and
- Range of British sizes: 6 3/8 – 7 7/8.
- International sizes for children are based on their age.
How do you measure the head of a hat?
Hat sizes are based on head circumference. To measure it correctly:
- Take a measuring tape.
- Find the part that protrudes the most at the back of your head and connect it to the most protruding part of your forehead using the measuring tape, leaving a gap of approximately 0.4-0.8 in (1-2 cm) above your ears.
- Complete the circumference and write down the result
