Hat Size Chart

We want to make sure that your hat is the perfect fit. Therefore, we have created a measuring guide and size chart to ensure you select the right hat size.

Steps to accurately measure your head:

  1. Using a soft dressmaker’s tape measure, start at the front of your head just above your eyebrows and measure all the way around your head – See below images for reference
  2. Measure in centimetres for the most accurate fit
  3. Check our hat size chart below to work out your size
