This motorcycle helmet fitting guide/video is based on advice from Sharp, The Helmet Safety Scheme. Motorcycle helmets only offer maximum protection if they fit correctly. It’s highly recommended not to simply guess the size, because every head shape is different and taking time to ensure the best fit is extremely important. Whilst different brands can vary in their sizing, a good starting point is being properly measured and to select the corresponding helmet size. Be aware that this initial selection might only be the starting point, as head shape can vary from person to person, meaning that sometimes a particular brand will naturally offer the best fit.

How to correctly fit a motorcycle helmet
It is important to always try a helmet on. Start by placing the helmet firmly on the head. Secure the chin strap so that two fingers can fit between the strap and chin. Check for a good fit between the helmet – around the sides and rear of the head. If there are gaps at the top, the helmet is too small.
The motorcycle helmet should be in contact with all of the head, but it is important that there are no pressure points – a common one being where the helmet makes contact with the forehead. Once a helmet has been found that ticks all the boxes, common advice is to then wear the helmet for a few minutes to ensure that it is fully comfortable.
Try rotating the helmet from side to side. With a full face helmet, the cheeks should follow the helmets movement and remain in contact with the cheek pads firmly, but comfortably. If the helmet moves freely or slips on the head, it is probably the wrong size.
Next, try moving the helmet both forwards and backwards and again, if it moves freely or slips, it is likely the wrong size. The helmet must stay firmly on the head – so with the chin strap secured as already explained, tilt the head forward and carefully apply upward pressure at the base of the helmet to ensure that it cannot roll forward.
