How to Measure Your Head
Wrap a soft measuring tape around your head, about half an inch above your eyebrows and ears. This is your circumference.
Size Comparison
| Circumference (cm) | US Size | UK Size | EU Size |
|---|---|---|---|
| 55 | 6 7/8 | 6 3/4 | 55 |
| 57 | 7 1/8 | 7 | 57 |
| 59 | 7 3/8 | 7 1/4 | 59 |
| 61 | 7 5/8 | 7 1/2 | 61 |
Pro Tip
If you're between sizes, go up and use a hat reducer (a small foam strip) for a perfect fit.
Key Takeaways
- US sizes are slightly larger than UK sizes
- EU sizes are just the circumference in cm
- Specialized sports caps (like New Era) use specific US sizing
