Helmets are important for safety and their primary purpose is to protect your head from fractures and injuries in the event of a crash. It’s not enough to just buy a helmet, it is even more important to have a helmet that fits your head properly and does not in any way hinder your comfort. It mustn’t be heavy, and at the same it shouldn’t be too light as that may show a sign of inferior quality. Just somewhere around the middle where it is sturdy enough to withstand high impact without weigh you down.
Apart from the fact that a wrong sized helmet for you can hinder your comfort, if oversized, it can easily come off your head just when an accident is about to happen even if it’s well strapped to your head. More so, if it does not come off totally but hangs on probably your neck or thereabout, it could even result to serious injuries. Thus, the need for going for a helmet that fits you just right.

The simplest and easiest way to quickly determine the ideal helmet size for you is to have an idea of your head measurement. Being informed of your head shape and size will give you an accurate idea of the size of helmet to go for in order to get the highest level of comfort and protection.
Identifying the Perfect Helmet Size
The are basically two ways to go about this. The first method involves wearing the helmet on your head and the second involves using your head dimensions to determine the size to go for. In order to measure your head size, you will need a tape measure, a note, and a pen.
With the help of the tape, take the measurement at the region having the fullest part of your head. More preferably, you can do this around the forehead region just a bit above your ears. That will help you to know the circumference of your head and where it is widest which is obviously at the forehead area.
With the pen and the note, record the sizes measured in both inches and centimeters. Afterwards, you check the size chart to see which of the helmets best fit your head.
Different Shapes of Head
Usually, head shapes which are used as standards for helmet designs are round, oval, and egg shapes.
- Round: for this shape, the head is wider around the mid region in the temples area of the head.
- Oval: it is referred to as ‘long oval’ shape. Out of the three shapes, oval shapes are the most common.
- Egg: for this shape, it means the head is narrower at the bottom region and wider at the top.
