How do I find the right-size Ballistic Helmet?

The ballistic helmet you choose must be comfortable for you, whether you’re on a high-risk overseas mission, a US law enforcement officer, or for tactical leisure activities.

The best helmet size is important to ensure the perfect fit. It will improve your performance as well as increase your safety.

We will show you how to select the right size and give tips on choosing the best ballistic helmet.

The helmet is the oldest protective gear, dating back to the 23rd Century BC. Modern ballistic helmets are lighter and more durable than traditional ones. They can be made from carbon fiber, Kevlar, or high-impact plastic.

Innovative designs are intended to offer a high-performing, efficient solution for combative operations, including law enforcement and the military.


Knowing that your tactical helmet can protect you from harm when shopping for one is important. It must have been tested thoroughly and meet the US military standards.

These are the top three characteristics to consider when selecting a tactical helmet.


Your helmet may block your field of view if it is too low to your head. It can hinder the effectiveness of your eyewear and may even lead to reduced agility on the battlefield.

The typical size of a shell head is small (S), medium, large (M), and extra-large(XL). Although these sizes may vary depending on the brand and manufacturer, they usually correspond to the following:

S = 20in or less (54cm or under)

M = 20in – 22in (50–56cm).

L = 21in – 24in (54–60cm).

XL = more than 24in (over 60cm).

To be sure about the helmet you are interested in, it is a good idea to check with the manufacturer.

This guideline will help you determine the right size helmet for you.

  1. Place your feet on the ground.
  2. Your comrade should measure the length of your head. Your comrade should measure your head from the middle of your brows to your back. A tape measure or a caliper are both options. Take measurements.
  3. Next, measure your head width. You will need to measure the length of your head from left to right. Your comrade will position the tape measure or caliper just above your ears. Remember to take measurements.
  4. Take your maximum head circumference measurement and keep it. Be sure to keep your head up. It is best to measure just above your bony brow ridges and pass the tape measure just above your ears.
  5. Check with the helmet manufacturers to get the best recommendations based on your measurements.


The risk of your tactical helmet becoming unstable is high if it sits too high. Unfitting helmets can lead to headaches and distract you from your mission.

Soft focus can lead to injury or even death on the battlefield. That means that stability is important when choosing your Military Helmet or tactical helmet.

Now the question is, how can you tell if the fit is right for you? These are some indicators to keep in mind:

  1. The chin strap/belt on tactical helmets is typically four-point. By tightening the belt, check that the helmet is snug but not too tight or loose.
  2. Make sure the helmet’s crown pads reach the top of your head.
  3. You can look up using your eyes, but don’t tilt your head. The rim of your helmet should be visible. The helmet may need to be looser or higher if you can see its rim. The helmet may need to be bigger to fit your head if you cannot see the rim.
  4. Your tactical helmet must stay in place when you shake your head or move.
  5. Ask a friend to check your helmet’s stability. The front rim should be approximately 1/2 inch above the eyebrows.


Ballistic helmets should be comfortable for the wearer. A good helmet will not hinder your performance and can even increase safety and protection during combat.
