How to Measure Your Hat Size
- Take a measuring tape and wrap it around your head, slightly above your ears and eyebrows. This is where the hat will sit.
- Make sure the tape is snug but not too tight - you want your hat to be comfortable.
- Note the measurement in centimeters or inches.
- Use our converter above to find your size in different sizing systems.
Hat Sizing Tips
- If you're between sizes, go for the larger size.
- Hat sizes can vary between manufacturers, so always check the specific brand's size chart when available.
- Some hats are adjustable and may be labeled as "One Size Fits Most".
- Consider the hat material - natural fibers like cotton or wool may shrink or stretch over time.
