S = 20 inches and under (54 cm and under)

Medium = 20" - 22" (50 - 56cm)

Length = 21" - 24" (54 - 60cm)

XL = over 24 inches (over 60 cm)

Have your partner measure the length of your head. Have your partner start from the middle of the brow to the back of the head. You can use calipers (preferred) or a tape measure. Record the measurement results.
The next step is to determine your head width measurement. Do this by taking the widest length between the left and right sides of the skull. Have your partner hold a caliper or tape measure above your ear. Again, don't forget to document your measurements.
Now, get your maximum head circumference and record the measurement. Remember that you are sitting upright. It is best to measure just above the bony brow ridge while passing the tape over the ear.
You can consult the helmet brand for the best advice on helmet size based on your measurements,
Stabilize
If your tactical helmet sits too high, the risk of its instability is high. Loose helmets can be a nuisance, not only reducing your concentration but causing you annoyance.

Remember, on the battlefield, a lack of concentration can get you injured and even cost your life. This means that stability is a key factor in choosing a tactical or military helmet.

The question is: how do you check if it's right for you? Here are some metrics to keep an eye on:

Tactical helmets usually have a four-point chin strap/belt. Pull the seat belt tight and check that the helmet fits snugly, but not too tight and not too loose.
Check that the crown pad of the helmet reaches the top of the head.
Look up with your eyes and don't lift your head. You should see the edge of the helmet. If you can see the inside of the helmet, it's probably too low and loose. If you can't see the rim, the helmet may be too small for you, causing it to sit too high on your head.
When you move your head from side to side or shake your head, your tactical helmet must stay in place.
Ask your comrades to evaluate whether your helmet is stable. He should see the front edge about a half inch from the top of the brow.
comfortable
The wearer should feel comfortable when using a ballistic helmet. A good helmet won't affect your performance and can even improve the protection and safety of the wearer, especially in combat.
