How to measure
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.
Once you know the circumference of your head, select a size with a range that your head size fits within.

As well as an adjustable chin strap the majority of cycling helmets have some form of adjustment for size, usually in the form of a ratchet adjuster to tighten or loosen the headband or replaceable pads of different thicknesses.
