What size am I? Does size really matter? Will I be judged if I have a small one?

We’re talking about a motorcycle crash helmet of course. In the UK the helmet is a legal requirement and they can range in price from £29.99 to more than £3,000.

First things first though. It’s vital that you chose the correct size, you don’t want to spending money on a lid that doesn’t fit correctly or hurts over 40 mph. So together with our chums over at BikeNation we’ve put together a simple-to-follow guide with accompanying video.

Once you’ve chosen the style of helmet you want, it’s all about making sure you’ve got the right size for safety and comfort.

1. Measure

The first thing you need is a tape measure to measure you r head. You can always use a piece of string and then offer it up against a builder’s tape measure.

Put tape measure around the biggest part of the head, slightly above the eyebrows and ears. Then you can check the measurement against the manufacturers sizing chart.

2. Try the helmet on

It’s important to note the different brands have different sizing so just because you’re a medium in one brand, you could be a large in another. Try different sizes and brands, everybody’s head is a different shape so give plenty of helmets a go, you never know which might suit you. Also, make sure you know how to fasten the helmet; some have clips, others have D-rings.

3. Check for a proper fit

Make sure it’s nice and tight but you don’t want it too tight. Comfort is all-important. There could be occasions where you’re riding for several hours so you need it to be as comfortable as possible. Make sure it’s not hurting anywhere. Start with feeling how close the helmet is around your cheeks; make sure there are no gaps. Then move up to your temples and forehead, you don’t want to be able to get your fingers in there. And finally, check the back of the crash helmet; if it’s snug then it’s the right size for you.

4. Roll the helmet forwards and backwards

The final check is to get hold of the front and back of the helmet and wiggle it forwards and backwards. You want it to move a little bit and obviously not to come off or lift while you’re riding.

Make sure the helmet is a snug but not tight fit

If you can safely say that it’s the most comfortable thing you’ve ever worn then you’ve found the helmet for you. But remember that sizing differs with each manufacturer so don’t be afraid to try as many as you want until you’ve got the perfect helmet shape and size for your head.
