To accurately measure your head, use a cloth tape measure wrapped around your head horizontally about one inch above your eyebrows and ears, take the CM measurement of the circumference of your head.
NOTE: Always aim to get a tight fitting helmet, if you fall between sizes round the size down, not up. The exception to the rule being kids as they are growing you would be safe to round up to the nearest CM to allow for room to grow. Everyone has a slightly different shaped head, and most helmets are a slightly different fit from brand to brand.
