I make custom made hats where your measured size is used to cut the sweatband correctly for the best fit.
- Use a soft ruler to measure your head circumference size at the largest part of your head, one fingers width above your ears. Just let the ruler simply rest on your head, not too tight or too lose.
- For correct hat size, add 0.5 cm for a comfortable fit.
Tip: Looking straight into a mirror and letting the ends of the soft ruler meet at your forehead makes it easier to read the specific size.
