How do I measure the circumference of my head correctly?

You can measure the circumference of your head (which corresponds directly to your required hat size) in no time at all using a tape measure.

Take a cm tape measure and hold it snugly, but not too tightly, around the widest part of the back of your head and over the centre of your forehead above your eyebrows. The tape measure should be around 1 cm above your ears.

Using your personal measurements, you can then select the corresponding size from the following measurement table. Kastori hats are available in the sizes S, M, L and XL.
