To measure your head, simply take a tailor's tape measure and wrap it around your head just above the ears, making sure that you are not pulling too tightly as this could result in an inaccurate measurement. Getting a measurement in centimeters is the most accurate method of measuring your head as sizing for different companies can sometimes vary.
