How to Buy and Measure Harley Davidson Helmet Size?

Like shoe sizes or any clothing items you wear, you need to measure your head to know which size of helmet is suitable. 

Because, if your helmet is not properly fitted over the head, it won’t be comfortable and effective to protect your brain from being injured. 

So, it’s crucial to know how you can measure your Harley Davidson helmet size. Here the steps you should follow to do so: 

Step 1: Select the helmet’s type 

Before measuring your head, it’s important to consider a particular type of helmet as you like it. There are typically five different types of helmets that include: 

  • Open Face Helmets

Open face helmets are more ventilated and easier to get on and off. Therefore, this type of Harley Davidson helmet will feel less restrictive. 

But they have some drawbacks too. The main drawback of an open face helmet is that there’s no protection for your face. 

  • Full Face Helmets 

This type of helmet might be the most typical Harley Davidson helmet you’ll see on the street and racetrack. 

A full face helmet is designed with a chin bar as well as a built-in face shield to protect your face and eyes. 

The other additional benefit to all of this protection is that it’s quieter than an open face helmet. But it may seem a little bit harder to get on and off. 

  • Modular Helmets 

Nowadays, modular helmets are getting popular among both commuting and touring riders. One of the most important features of a modular helmet is that one can easily open it at the chin bar. 

This feature makes it easiest to put on and off. Moreover, the modular Harley Davidson helmets include anti-scratched sun shields. They’re also resistant to fog and come with washable interiors. 

Now the only drawback to these helmets is that they are slightly heavier and noisier than traditional full face helmets.  

  • Adventure Helmets

This type of helmet is designed for folks who like to ride both on and off road. Because they are usually more comfortable and quiet. 

The best thing about these helmets is that you can still use your goggles while wearing the helmet. 

But the adventure helmets can feel a bit heavier as well as not well ventilated. 

  • Dirt Bike Helmets 

Dirt bike helmets are especially designed for off-road riding. While using a dirt bike helmet, one can get a massive amount of ventilation. They’re also typically very lightweight and easy to clean. 

However, the dirt bike helmets might not be street legal. They can also feel a bit noisier.

Step 2: Determine the shape 

Once you’ve got your required helmet type, you have to determine the helmet shape. The helmet shape is crucial for most helmet types.

Usually, there are three general helmet shapes categorized as round oval, intermediate oval, and long oval. 

  • A round oval helmet is slightly shorter front-to-back with a bit of additional room at the side of the head. 
  • An intermediate oval helmet is a little bit longer front-to-back and slightly narrower at the side of the head. 
  • A long oval helmet is long front-to-back and narrow at the temple. 

Step 3: Measure the size 

Once you’ve determined your helmet shape, finally it’s time to choose the correct Harley Davidson helmet size. 

To measure your helmet size, all you need is just a measuring tape, especially the fabric one. 

Also, it’s better to measure in centimeters and not in inches. It will be more accurate for the helmet size. Now let’s see how it goes: 

  • First of all, place the measuring tape approximately 1-2 cm above your eyebrows.
  • Now measure your head circumference twice or thrice until you get the largest measurement. 
  • Once you’ve got the largest circumference measurement, match it up with the Harley Davidson helmet size chart that we discussed earlier.
  • While matching the measurements, if you’re between the two different sizes, go by the smaller helmet size for the best fitting.

Is it better for a motorcycle helmet to be tight or loose? 

It is not better for a motorcycle helmet to be tight or loose. If the helmet is too loose, it won’t function properly and can slide off while riding. It will also feel uncomfortable and can come off when there’s an accident. 

On the contrary, if the helmet is smaller or too tight, it will get stuck on your head. You can also feel constant pressure around the head which is breakneck too. 

So, motorcycle enthusiasts always recommend snug fitting motorcycle helmets. A motorcycle helmet should be firmly snug without any pressure points. 

It should be firm so that it doesn’t move around on your head, but not so tight that it gives you a headache.
