  • Select a helmet style

Today, the choices of motorcycle helmets are plenty and wholesome. While it’s pleasing to have so many options, it can still be rattling to pick the perfect size.

The first step is to select the type of motorcycle helmet you need, as there are five different types of bike helmets available. Let’s dig into them:

  • Open Face Helmet: One of the least protective and restrictive helmets on the list. Open face helmets are open, and they don’t cover the chin, so be prepared to accept a cold breeze hitting your face while you ride.
  • Modular Helmets: These helmets incorporate a hinged functionality to swing the face and chin-bar guard away when the rider hits release. As a result, they transform from a full-face bike helmet to an open face.
  • ADV Helmet: An Adventure Helmet mimics the protection you need for the trail, single, or street riding. 
  • Full Face Helmet: This one is easy; it covers your entire face.
  • Dirt Helmet: It is exclusively for off-road motorcycling. These helmets are not street-legal. They offer a massive peak, plenty of airflows, and should be worn with protective goggles. 
  • Measure your head size and shape

An essential step on how to size a motorcycle helmet is to measure your head’s shape and size.

 Now that you are aware of the types of helmets let’s move on to the par where we start measuring. Usually, people find any one of the three shapes suitable: round oval, long oval, and intermediate oval.

Before wearing the helmet, flatten your hair as much as you can, then take a photo of your head from the top. Look at the picture and determine the shape of your head. Is it long oval, intermediate oval, or round oval?

After that, determine the helmet size. The good news is, the process will not take long. Use a measuring tape to measure the circumference of your head. Additionally, make sure the tape runs around the back of your head and on top of your eyebrows. 

However, you can do this yourself, but its best to let a helping hand do it. After measuring, move it towards a ruler to determine the length. Compare your results with a helmet size chart to know the correct size.

  • Put the helmet on 

After executing the above steps, it is time to narrow your choices to one motorcycle helmet. When you select the motorcycle helmet, please put it on, and check the spreading of the straps. 

You must understand that not all helmets feel comfortable when you pass them through your head. You may need to settle your ears, and that is normal. As long as you analyze your pick from the motorcycle helmet size chart, your choice should be perfect.

  • Determine the proper fit 

That is the part where you ask yourself, how does the helmet feel? If you notice any discomfort, consider replacing your choice with a more comfortable one. If the helmet fits properly, you must contact the cushions pressing against your cheeks. 

After that, pick the chin-bar and change its position. While doing so, your helmet must not move. If the helmet slides, consider a smaller size.

  • Test the bike helmet by wearing it for half an hour

Put the helmet on for at least half an hour. You can spend time watching TV or cooking. 

Remember, it is okay if the motorcycle helmet is tight, but if you have to take it off to have relief from the pain, change your helmet. Besides that, if the motorcycle helmet leaves a red line on your forehead, go for something else.

You cannot spend these 30 minutes while riding because most dealerships do not return their motorcycle helmets if you ride with them.

  • Does it feel comfortable and functional? If yes, then take your motorcycle for a spin!

If the 30-minute test succeeds, make your purchase! You have to make sure you feel comfortable while wearing the helmet. Also, the motorcycle helmet will mold into the shape of your head after some time, making it an even more comfortable fit.
