How to Measure Your Hat Size?
Getting the right measurement is key to finding the perfect fit. It's easy and only takes a minute.
1. Get a Soft Tape Measure
Wrap it around your head, about 1/8" above your ear.
2. Find the Circumference
Go across the mid-forehead, completely circling your head.
3. Read the Measurement
Hold the tape firmly, but not too tightly. Use the measurement in inches or cm in our converter.
Why Accurate Measurement Matters
A proper measurement is the difference between a hat you love and one you return. An accurate size ensures better comfort, prevents headaches from a tight fit, and makes sure your hat looks exactly as it was designed to. Take one minute to measure, and save yourself the hassle.
