The circumference of your head provides a good guideline for the size you need for a helmet. Use a tape measure to measure the widest circumference of your head. For most people, this point is about an inch above your eyebrows, along the junction of your ear and over the lump on the back of your head. In the size chart you will find which size fits the circumference of your head in cm.
All heads are different and that is why manufacturers make different helmet shapes, this can be roughly categorized into three shapes: round, oval and round-oval.
Most motorcycle helmet manufacturers provide a predominantly round-oval fit so that they can appeal to the widest possible audience. Keep in mind that the fit of a helmet is very complex and difficult to describe exactly. Small differences may therefore also be possible within these three categories!
In general, the helmet sizes and the corresponding number of cm do overlap. If your previous old AGV was size L, chances are you also need an L for your new Nolan. But as mentioned before, there can be small differences in fit per brand and even series. That is why it can happen that the cool new helmet you've been eyeing, even when you have measured yourself well, simply wont fit well.
You can check the size and fit in the following ways:
A good "tight" fit is what you are looking for, after all, you don't want your helmet to suddenly start shifting while riding. If you think the helmet is too small, keep in mind that the inner lining hase to be worn in a bit, and the helmet will become a bit wider when used. The cheek pads in particular usually feel quite tight in the beginning but quickly become more comfortable. The best way to determine whether a helmet has a good tight fit or simply is to small, is to keep the helmet on at home for half an hour to an hour. If you don't start to suffer from a headache or get red pressure spots, Then it's all good!
The ECE (22.05 / 22.06) standard is recognized in many countries around the world, but not all countries accept this standard for road use. It is important that your specific helmet has the correct certification for the country you are in.
The USA does not require helmets in every state. If you still want to wear a helmet for safety reasons, then there can in any case be no discussion about the certification of the helmet. Want to know which rules apply per state? You read it here.
Although the above quality marks are well known and widely used, there are also countries that use their own unique quality marks and only accept these. The following countries have their own certification: USA (DOT), Brazil (NBR), Japan (JIS), China (CCC).
