Choosing the right size is one of the most important parts of buying a motorcycle helmet. Use the guide below to measure your head and compare your measurement with the appropriate Hedon size chart.
Measure around the widest part of your head, approximately 2cm above your eyebrows, passing just above your ears and around the back of your head.
Use a soft tape measure and record the measurement in centimetres.

If you're between sizes or unsure which helmet is right for you, we're always happy to help.
Your head shape can affect how a helmet fits, even when the circumference measurement is correct.
Hedon helmet models suit slightly different head shapes, so use the illustration below alongside the individual size charts.

The Hedon Heroine Racer 2.0 Eemes is a handcrafted full-face motorcycle helmet from Hedon’s Art of Protection collection, where art, design and function come together. Inspired by the colours and comfort of the iconic Eames Lounge Chair and Ottoman, Eemes translates that influence through a metallic rust shell, satin finish, black leather and brass detailing.
Designed and developed in London, the Heroine Racer 2.0 combines an ultra-lightweight, low-profile composite carbon-fibre shell with modern ECE 22.06 protection. The four-position visor mechanism gives you greater control over airflow as conditions change, while the wide field of view and three-channel ventilation system are designed for comfort out on the road.
Inside, Hed Armour 360° cushioning, Merlin antibacterial fabric and black leather lining create the close, comfortable interior Hedon is known for. Hedon’s soundproofing helps reduce wind noise for a quieter ride, bringing another practical layer to a helmet where comfort is as considered as its appearance.
The Heroine Racer Eemes takes inspiration from one of the most recognisable pieces of modern furniture design and reinterprets it for the road, bringing together warm metallic colour, black leather, brass and carbon fibre in a full-face helmet that remains unmistakably Hedon.
Eemes is a seriously good-looking helmet. Metallic rust satin paint, black leather, brass detailing and exposed carbon fibre give it real character. Inspired by iconic design and developed in London, it combines a lightweight, low-profile shell with Hedon’s soundproofing and ECE 22.06 protection — there’s plenty behind the looks too.
