Most motorcycle industry experts state how tight a full-face helmet should fit. The helmet should fit snugly around the rider’s head without resulting in any pressure points. The helmet should fit as snug as possible while still being comfortable. A full-face helmet should not be able to move around on the head.

There should not be any side to side or up and down horizontal or vertical movements when the helmet is seated properly on your head. You should not be able to push the chin guard into contact with any part of the front of your face. 

The helmet should fit as tightly as possible while still being comfortable. If the helmet has high pressure points or is just too tight overall, then you have chosen a helmet that is too small. There are also different shaped heads and some of the helmet manufacturers offer models with different shape liners to fit several head shapes. Examples of this are round, round oval, and long oval liners.

How Snug Should a Full-Face Motorcycle Helmet Fit? How Tight Should Full-Face Helmet Fit?

A full-face helmet should have a comfortable but snug fit all around in the easiest way to check this is by seeing if the helmet moves around on your head and if it can be rotated easily by hand. If so, the helmet is loose, then it is too large and is unsafe.  A loose helmet has a much higher likelihood of coming off in the event of a crash.

However, you do not want to helmet that is so snug that it is tight and gives you a headache or causes any pain or discomfort in any other area, such as the jaw or chin. A helmet that is too tight can be uncomfortable to ride in but a helmet that is to lose can be dangerous or even deadly.

Overall Helmet Fit

Most people focus on whether the helmet is too tight or too loose, but another consideration is how it sits on your head. A properly fitting helmet should sit level on your head with the front edge of the eye ports less than an inch above your eyebrows, so that the foam liner offers protection to the forehead in the event of an impact. It is important when fitting a helmet that you do not have the helmet tilted forward or backwards, and that it is resting level on your head.

Once this is done and the helmet feels snug but not painfully tight. You should be able to confirm that the helmet will not move freely on your head by pushing it with your hand from the back and the front as well as side to side. 

Should a Full-Face Helmet Squeeze Your Cheeks?

A full-face helmet should be snug enough that it squeezes your cheeks. It should not be painful or cause you to bite the side of your cheeks, but if it is not squeezing your cheeks firmly then it is for sure, too large too loose. Can you chew gum with your full-face helmet on? If the answer is yes, the helmet is too large.

Is It Normal for a Helmet to Be Tight?

Many new riders make the mistake of thinking a helmet is too small because of how tightly it goes on to the head, especially compared to an open face helmet. Full-face helmets are designed this way, and the next role and cheek pads will always make that entry into the helmet tighter and more compact than when the helmet is fully seated on the head. A good fitting helmet should be quite snug, especially when new after you wear it for some time, and it will break in some to the shape of your individual head.

Is It Better for a Helmet to Be Too Small or Too Big?

Ideally you want a helmet that is neither too small nor too big.  A a helmet that is too small, uncomfortable, but a helmet that is too big can be outright dangerous. It’s always better to air on the side of too snug than too loose. If you can slip your fingers between any part of your head and the helmet, even one finger, then the helmet is too loose, and you need a smaller size.

Can Tight Helmet Cause Headache?

Yes, wearing a helmet that is too tight can cause a headache. When the liner and comfort padding are too tight it is possible to cause an external compression headache, which is caused by pressure over the forehead or scalp. Additionally, depending on the shape of your head a single pressure point, especially in the four head area or in the temporal area can create discomfort and create a headache

Do Motorcycle Helmets Loosen Up Over Time?

As a motorcycle helmet is worn and as it ages it will loosen up over time. The amount that a helmet will loosen up depends a lot on the brand of helmet and the price level as the quality of the materials used in the foam padding are the biggest factor in why helmets loosen up over time. The shell will not change, and even the EPS liner will not change very much either. A few of the pressure points the high spots, if any, may disappear after some time. The main area that will affect the motorcycle helmet loosening overtime is the comfort.

All the various foam materials and fabric used in the comfort patting and liner will tend to compress and age over time and this will count 95% or more of any loosening. Many of the more expensive new helmets on the market can have the comfort patting replaced. But most riders would just want to buy a new helmet at that point.

Helmets will not loosen up in a few hours or even a few days and not even in a few weeks. Please disregard any information you read that says wearing your helmet around your house for a few hours will break the helmet in, so it is comfortable. Most helmets will loosen up over months of constant use or several months of infrequent use.

How To Fit a Helmet – Measuring

The best way to fit a helmet is to be able to try it on. If you are buying online, and do not have that option then Plan B would be to get a tape measure to calculate the circumference of your head. But be aware that humans have many different shaped heads and that although a tape measure may produce the same numerical measurement on different riders’ heads, they may not all fit properly in the same size helmet.

Additionally, shapes and sizing are very by manufacturer, which is another good reason to try helmet on person before purchasing it. You should measure the circumference of your head from about 1 inch above the eyebrows going straight back to the rear part of your head. It is best to take multiple measurements or even have someone else take the measurements for you and again do it several times until you produce the same number consistently.

How To Fit a Helmet – Review of General Tips

The helmet should not go on too easily, it needs to be snug and comfortable when it is seated on your head. But it is preferable that it is a little bit of a squeeze to get it on as the neck role and comfort padding should be quite tight at the opening of the helmet.

The cheek pads should be firmly pressed against your cheeks. The simple, low-tech, effortless way to check this is to see if you can chew gum with your helmet on. If so, it is too loose. It is important that the cheek pads fit very snugly because they are what keep the helmet in the proper position and help keep the helmet from rotating while riding or in the event of a crash.

In no instance should it be possible to remove the helmet if the chin strap is properly secured. If you can pull the helmet off with the chin strap secured, then the helmet is too large and is not safe.

It is always better to try a helmet on, in person, and to buy one online. You already purchased a specific model and brand, and you want another one buying online can define once you are familiar with the shape of your head and the way particular manufacturers helmets fit but for first-time purchase is difficult to properly fit a helmet by just measuring your head and then purchasing sight unseen online.

Different helmet brands fit in diverse ways and is quite possible that the same size in different helmet brands will fit your head quite differently so it is impossible to say you are a certain size because that may be only correct for specific brands or even models.

The helmet should fit as snuggly as possible without causing discomfort or pain. Over time you will feel quite comfortable with the added security of a well-fitting helmet. In fact, if you ever put on a loose-fitting helmet, it will feel very strange and awkward.

Your helmet should not be able to move around on your head even if you shake it. It should not slide around and never tilt back or come down over your forehead or move side to side. This is the single most important safety factor when wearing a new helmet.

A helmet that is too loose can come off your head. Even with the chin strap rigidly attached a loose-fitting helmet that is too loose can come off in what is called “roll off”. If the helmet is loose can move around so much that it can block your vision while you are riding.

How To Fit a Helmet If You Wear Glasses?

Many modern motorcycle helmets have comfort padding designed to accommodate eyeglasses and sunglasses. To be sure about the fit try on your glasses with the helmet before you purchase them.

 

MICHAEL’S SUMMARY & CONCLUSION

There is a myriad of factors that a motorcyclist must take into consideration when choosing which full-face motorcycle helmet, they will purchase.

  • Safety Standards
  • Comfort
  • Weight
  • Shell Style
  • Peripheral vision
  • Face shield mechanism and optics
  • Quietness
  • Paint and Graphics
  • Brand identity
  • Secure fit.

While all these things are important. Nothing is more important than to have a helmet with a secure fit. If a helmet rolls off in the event of an accident. It does not matter what standards it meets, or any other factor. They all become quite irrelevant. A secure fit with a Double D style retention system is the single most important safety aspect you should be concerned about.
