How To Measure Your Head
So, you’ve found the hat that you love, but you have no idea what your head size is. Here is how to find out.
Take a flexible tape measure and measure the circumference of your head.
The tape should be parallel to the floor, cross just above your eyebrows, and about 1-2 cm above your ears at the sides. Don't pull it super-tight, just comfortably snug.
If you don't have a tape measure then mark your head circumference on piece of string which you can then measure against a flat ruler.
Note the measurement to the nearest centimetre; round up for a looser fit, round down for a tighter fit, whichever you'd prefer.
Done! Now you know your head size in metric.
And here below, we’ve provided a chart so that you’ll always know your size in different conversions:
