How to Measure for Snowboard Helmet?

The first snowboard helmet I bought looked perfect on the store shelf. It had great reviews, a clean design, and all the safety features I wanted. I thought I had made the right choice. Then I wore it for a full day on the mountain in Colorado, and everything changed. About an hour into my first run, I felt pressure across my forehead. By lunch, I had a headache. That was when I realized I had skipped the most important step—I never learned how to measure for snowboard helmet the right way.

Since then, I never buy a helmet without measuring my head first. It only takes a few minutes, but it can save you from an uncomfortable day on the slopes or an expensive return. More importantly, the correct size helps your helmet protect you the way it was designed to during a fall.

Whether you ride fresh powder in Utah, groomed trails in Vermont, or weekend resorts around Lake Tahoe, the fit of your snowboard helmet matters just as much as its safety rating. Cold weather, thick base layers, and long days on the mountain make comfort even more important. A helmet that fits well stays secure without creating pressure points, even after several hours of riding.

In this guide, I’ll show you exactly how to measure for snowboard helmet sizing based on what has worked for me over the years. I’ll also share the small mistakes I made, explain how to read helmet size charts, and help you find a fit that feels comfortable from your first chairlift ride to your final run.

How to Measure for Snowboard Helmet?

Measuring your head is simple, but doing it correctly makes a big difference. I follow the same process every time I buy a new snowboard helmet, whether I shop online or visit a local outdoor store.

The Quick Answer

If you only need the short version, here it is.

To measure for a snowboard helmet:

1. Use a flexible measuring tape.
2. Place it about one inch above your eyebrows.
3. Wrap it around the widest part of your head.
4. Keep the tape level all the way around.
5. Record the measurement in centimeters.
6. Compare it with the helmet brand’s sizing chart.

That simple process gives you the best starting point before trying on any helmet.

Why Measuring Your Head Matters?

I used to think snowboard helmet sizes worked like baseball caps. If I wore a medium in one brand, I assumed a medium would fit everywhere. That turned out to be completely wrong.

Every manufacturer uses slightly different shell shapes and padding. Even two helmets with the same size label can feel very different once you put them on. Measuring your head removes the guesswork and helps you narrow your options before you spend money.

A proper measurement also improves safety. During a crash, a helmet works best when it stays in the correct position. If it slides forward, shifts sideways, or lifts off your forehead, it cannot protect you as effectively.

What You’ll Need

The good news is that you probably already have everything you need at home.

I usually grab these items before measuring:

• A flexible measuring tape
• A mirror
• A notebook or phone
• A helmet size chart from the manufacturer
• A friend if I want a second set of hands

If you do not own a sewing tape measure, you can use a piece of string and measure it afterward with a ruler.

Where to Place the Measuring Tape?

This is the step that confused me the first time.

The tape should wrap around the widest part of your head. For most people, that means placing it about one inch above the eyebrows. It should pass just above the ears and continue around the back of your head at the widest point.

I always check my reflection to make sure the tape stays level. If it tilts upward or downward, the number may not be accurate.

When I first measured my head, I accidentally wrapped the tape too high across my forehead. My measurement was almost a centimeter smaller than it should have been. That tiny mistake almost caused me to order the wrong helmet.

Measure in Centimeters

Most snowboard helmet brands use centimeters because they provide more precise sizing.

While some stores list inches, centimeters are much easier to compare across brands like Giro, Smith, Oakley, Anon, and POC.

I usually write my measurement in both centimeters and inches, but I always shop using the centimeter measurement. It makes comparing different sizing charts much simpler.

Measure More Than Once

This may sound unnecessary, but I always measure twice.

Sometimes the tape slips. Other times I pull it tighter than I should. Taking a second measurement only takes another minute, and it helps confirm that the number is correct.

If my two measurements are slightly different, I take a third one and use the average. That habit has helped me avoid ordering the wrong helmet several times.

Step-by-Step Guide to Measuring Your Head

Once I learned the correct process, measuring my head became part of every helmet purchase. These simple steps work whether you buy your helmet online or in a local snowboard shop.

Step 1 – Remove Anything That Changes Your Head Size

Before measuring, I take off everything that could affect the result.

That includes:

• Thick winter hats
• Baseball caps
• Hair clips
• Bulky headbands

If you have long hair, wear it the way you normally do while snowboarding. I usually tie mine back in a low style because that is how I wear it under a helmet.

The goal is to measure the shape your helmet will actually fit over.

Step 2 – Wrap the Tape Around Your Head

Next, I place the measuring tape about one inch above my eyebrows.

From there, I wrap it around the widest part of my head while keeping it flat against my skin. The tape should pass just above both ears and meet again at the front.

I avoid twisting the tape because even a small twist can change the measurement.

Step 3 – Keep the Tape Snug, Not Tight

This is probably the biggest mistake I made when I first learned how to measure for a snowboard helmet.

I pulled the tape as tightly as possible because I thought that would give me a more accurate number. Instead, it made my measurement too small.

The tape should sit snugly against your head without squeezing it. Think of it as the way a helmet should fit—secure but comfortable.

Step 4 – Record Your Measurement

Once the tape feels level and snug, I write down the number immediately.

Most adult snowboard helmet sizes fall somewhere between 52 cm and 64 cm, although every rider is different.

I also save the measurement in my phone. That way, I always have it when shopping online or comparing different helmet brands.

Step 5 – Compare It With the Brand’s Size Chart

Now comes the most important part.

Do not assume every medium helmet is the same.

One brand may list 58 cm as a medium, while another considers it a large. I always check the sizing chart on the manufacturer’s website before making a final decision.

Those charts exist for a reason, and they have saved me from buying the wrong size more than once.

Step 6 – Try the Helmet On If Possible

Whenever I shop at a local snowboard store, I always try the helmet on before buying it.

A properly fitted snowboard helmet should:

• Feel snug around your entire head.
• Stay in place when you gently shake your head.
• Sit level across your forehead.
• Leave no painful pressure points.
• Work comfortably with your snowboard goggles.

I usually keep the helmet on for five or ten minutes instead of taking it off right away. Pressure points often appear after a few minutes, not the first few seconds.

That small habit has helped me choose helmets that stay comfortable through long days on the mountain.

The right measurement is the foundation of a safe and comfortable snowboard helmet. Once you know your head size and understand how different brands fit, shopping becomes much easier. More importantly, you gain confidence knowing your helmet is ready to protect you when every run counts.

How a Snowboard Helmet Should Fit?

Getting the correct size is only the first step. A helmet can match your head measurement and still feel wrong if the overall fit is not right. I learned this after trying several helmets that were technically my size but completely different once I wore them.

When I bought my second snowboard helmet, I thought measuring my head was all I needed to do. The size chart matched perfectly, so I ordered it without any hesitation. The helmet arrived a few days later, and I was excited to test it. Within ten minutes of wearing it around the house, I noticed a painful spot above my right temple. The helmet was the correct size, but its internal shape simply did not match my head.

That experience taught me that head circumference and helmet fit are not exactly the same thing. A properly fitted snowboard helmet should feel secure around your entire head without squeezing one specific area. It should stay in place naturally, not because you tightened the chin strap as much as possible.

Signs Your Snowboard Helmet Fits Correctly

A good helmet should almost disappear once you start riding. After a few minutes, you should be thinking about the snow, not about your helmet.

When I find a helmet that fits well, I notice several things right away.

• It feels snug around my whole head.
• It does not slide forward or backward.
• It stays level across my forehead.
• The padding touches my head evenly.
• There are no painful pressure points.
• My goggles fit neatly against the front of the helmet.

One simple test I always use is the shake test.

I fasten the chin strap, then gently shake my head from side to side and up and down. If the helmet moves with my head instead of sliding around, I know the fit is close to perfect.

Another test is to place my hand on the front of the helmet and gently push it backward. Then I push it forward. My skin should move with the helmet. If the helmet slides while my skin stays still, it is usually too loose.

The Helmet Should Feel Snug, Not Tight

Many first-time snowboarders worry that a snug helmet is too small.

I thought the same thing when I bought my first quality helmet.

A properly fitted snowboard helmet should feel firm around your head, but it should never create pain. Think about wearing a comfortable pair of winter gloves. They fit closely without cutting off circulation.

After wearing the helmet for fifteen or twenty minutes, I ask myself a few simple questions.

• Do I feel any sharp pressure?
• Is my forehead starting to ache?
• Does the helmet pinch my temples?
• Am I constantly adjusting it?

If the answer is yes, I usually try another size or even another brand.

Signs Your Helmet Is Too Big

A helmet that is too large can be almost as dangerous as one that is too small.

Extra space allows the helmet to move during a crash, reducing its ability to absorb impact correctly.

I have noticed these warning signs when trying oversized helmets:

• The helmet rocks from side to side.
• It slides over my eyebrows.
• The back lifts when I move it.
• My goggles leave a noticeable gap.
• I need to tighten the adjustment dial all the way.

If I notice more than one of these problems, I move down a size.

Signs Your Helmet Is Too Small

A helmet that is too small usually tells you very quickly.

The discomfort becomes obvious after only a few minutes.

Some common signs include:

• Pain across the forehead.
• Pressure near the temples.
• Red marks after removing the helmet.
• Headaches during long rides.
• Difficulty fastening the chin strap comfortably.

Years ago, I convinced myself that one helmet would “break in” after a few rides.

It never did.

Helmet padding compresses slightly over time, but the shell itself does not become larger. If a helmet feels painfully tight in the store, it will probably stay that way.

Don’t Forget About Your Goggles

One mistake I made early on was buying my goggles after purchasing my helmet.

The two did not work well together.

There was a noticeable gap between the goggles and the helmet, sometimes called a “gaper gap.” Besides looking awkward, that opening allowed cold air to reach my forehead on windy chairlift rides.

Now I always bring my goggles when trying on a new helmet.

I check that:

• The goggles fit snugly against the helmet.
• The strap stays in place.
• My field of vision remains clear.
• Nothing presses against my nose.

A helmet and goggles should work together as one complete system.

Wear It for More Than Five Minutes

This simple habit has saved me several times.

When I visit an outdoor store, I keep the helmet on while walking around for at least ten minutes.

At first, almost every helmet feels comfortable.

The real test comes after several minutes when pressure points begin to appear.

If I forget I am wearing the helmet, that is usually a very good sign.

Common Snowboard Helmet Size Charts

Your head measurement gives you a starting point, but every helmet company uses its own sizing guide. That is why I always check the manufacturer’s chart before placing an order.

One lesson I learned the hard way is that a medium is not always a medium.

I once owned a medium helmet from one company that fit perfectly. Later, I ordered another medium from a different brand without checking the size chart. The second helmet felt noticeably tighter even though both carried the same size label.

Since then, I compare my head measurement with every manufacturer’s recommendations.

Typical Adult Snowboard Helmet Sizes

Although every company is slightly different, most brands follow a sizing range similar to this.

Helmet Size	Head Circumference
Small (S)	52–55 cm
Medium (M)	55–59 cm
Large (L)	59–62 cm
Extra Large (XL)	62–64 cm

Treat these numbers as a general guide rather than a universal rule.

Why Brands Fit Differently

Several factors affect how a helmet fits besides head circumference.

Different companies design helmets with slightly different internal shapes.

Some helmets fit:

• Round heads better.
• Oval heads better.
• Narrow profiles.
• Wider head shapes.

Padding thickness also changes the overall feel.

This is why two helmets with identical measurements can still fit completely differently.

Always Check the Manufacturer’s Size Chart

Whenever I shop online, I visit the manufacturer’s website before adding anything to my cart.

Most companies provide detailed sizing information along with instructions for measuring your head correctly.

That extra minute can save the hassle of exchanging a helmet later.

Adjustment Systems Improve the Fit

Many modern snowboard helmets include adjustable fit systems.

These often use:

• Rear adjustment dials.
• Internal retention systems.
• Adjustable padding.
• Custom fit liners.

I like these features because they help fine-tune the fit without making the helmet uncomfortable.

However, I never rely on the adjustment dial to fix the wrong helmet size.

The helmet should already fit well before making small adjustments.

What If You’re Between Sizes?

This happens more often than people realize.

If my head measurement falls directly between two sizes, I consider a few things before deciding.

I think about:

• Whether I wear a thin helmet liner.
• The brand’s shell shape.
• The adjustment system.
• My hairstyle during winter.
• The manufacturer’s sizing advice.

In many cases, trying both sizes is the easiest solution.

A helmet that feels slightly snug often becomes more comfortable as the padding settles during the first few rides. A helmet that feels loose from the beginning rarely becomes secure enough later.

Choosing the right size chart and understanding how different brands fit has made helmet shopping much less stressful for me. Instead of guessing, I now rely on accurate measurements, careful fitting, and a little patience before making my final decision.

Should You Measure With a Beanie?

This is one of the questions I hear most often. I wondered the same thing before buying my first snowboard helmet. The short answer is no. Measure your head without a beanie, then decide what you normally wear while riding.

The first time I measured my head, I wore my favorite thick winter beanie because I assumed I would wear it under my helmet on the mountain. That small decision changed my measurement enough that I almost bought a helmet one size too large.

After talking with experienced riders and wearing different helmets over several seasons, I realized most snowboard helmets are designed to fit directly on your head or over a very thin helmet liner. Measuring with a bulky hat usually creates unnecessary extra space.

Measure Your Bare Head

I always measure my head without wearing anything.

That gives me the most accurate number and matches the way helmet manufacturers create their sizing charts.

Once I know my true head circumference, I can compare it with different brands without wondering if my beanie changed the result.

This simple habit has made online shopping much easier because I start with a consistent measurement every time.

Thin Helmet Liners Usually Work Well

On especially cold mornings, I sometimes wear a lightweight helmet liner.

Unlike a thick knitted hat, these liners are made to fit comfortably inside a helmet without changing the overall fit very much.

A quality helmet liner can help:

• Keep your head warm.
• Wick away sweat.
• Reduce itching.
• Improve comfort on cold chairlift rides.

If you normally ride with a thin liner, it is fine to try the helmet on while wearing one. Just avoid using bulky winter hats during the measuring process.

Thick Beanies Can Affect the Fit

I learned this lesson after one snowy weekend in Vermont.

I wore a thick wool beanie under my helmet because the temperature dropped well below freezing. Within a few runs, the helmet felt too high on my head, and the fit became unstable whenever I turned quickly.

The problem was not the helmet.

The extra fabric changed how it sat on my head.

A thick beanie can:

• Reduce stability.
• Create pressure points.
• Affect the chin strap position.
• Change how goggles fit.
• Make the helmet less secure.

That experience convinced me to leave bulky hats for the lodge instead of the slopes.

Balaclavas Are a Better Choice

When temperatures become extremely cold, I usually wear a lightweight balaclava instead of a heavy beanie.

Most helmet-compatible balaclavas are made from thin, stretchy materials that fit smoothly beneath a helmet.

They keep my face warm without creating extra pressure around my head.

For winter trips to places like Colorado or Montana, that combination has worked much better than a thick hat.

Measuring Kids for a Snowboard Helmet

Buying a helmet for a child feels a little different, but the measuring process stays almost the same. The biggest mistake I see is buying a larger helmet so the child can “grow into it.”

When I helped my nephew choose his first snowboard helmet, I thought buying a larger size would save money later.

Thankfully, the employee at the snowboard shop stopped me before I checked out.

He explained that a loose helmet cannot protect a child properly because it moves too much during a fall.

That advice stayed with me.

Measure the Same Way as an Adult

The process is simple.

Use a flexible measuring tape and wrap it around the widest part of your child’s head.

Keep the tape:

• About one inch above the eyebrows.
• Just above the ears.
• Level around the head.
• Snug without squeezing.

I usually measure twice because children tend to move around while I am trying to keep the tape straight.

Making the process feel like a game helps a lot.

Never Buy a Helmet That’s Too Big

I understand the temptation.

Kids grow quickly, and snowboard equipment is not cheap.

Still, an oversized helmet is not worth the risk.

A properly fitted helmet should stay secure without sliding across the forehead or rocking from side to side.

If a child needs to tighten the adjustment dial all the way just to keep the helmet in place, the helmet is probably too large.

Let Them Wear Their Goggles

Whenever possible, I let children try on their goggles while testing the helmet.

This helps me check:

• Helmet position.
• Goggle compatibility.
• Overall comfort.
• Field of vision.

Children are also more likely to wear safety gear happily when everything feels comfortable together.

Replace Helmets When Needed

Children grow much faster than adults.

I check helmet fit at the beginning of every snowboarding season.

A new helmet may also be necessary if:

• The child has a major crash.
• The helmet develops cracks.
• The padding becomes damaged.
• The helmet no longer fits correctly.

Protective equipment should always fit today’s head size, not next year’s.

Common Mistakes I Made When Measuring

Looking back, I realize most of my helmet-fitting problems came from simple mistakes. The good news is that they are all easy to avoid.

I spent far too much time guessing instead of measuring.

Once I started following a simple routine, buying a snowboard helmet became much less stressful.

These are the mistakes I try not to repeat.

Guessing My Helmet Size

For years, I assumed I knew my size.

Sometimes I guessed correctly.

Other times I did not.

Now I spend two minutes measuring before buying any new helmet.

That small step has saved me both money and frustration.

Ignoring the Brand’s Size Chart

This mistake cost me an unnecessary return.

I assumed every medium helmet would fit exactly the same.

It did not.

Now I compare my head measurement with every manufacturer’s chart before ordering.

Pulling the Tape Too Tight

I thought tighter meant more accurate.

Instead, it gave me a smaller measurement and almost convinced me to buy the wrong helmet.

The tape should feel snug, not tight.

That simple adjustment makes a noticeable difference.

Measuring Over a Hat

This was probably my funniest mistake.

I measured while wearing a thick winter beanie because I wanted to “be prepared.”

Instead, I only measured my hat.

Since then, I always measure my bare head and only test helmet liners after choosing the correct size.

Buying the Coolest Helmet Instead of the Best Fit

Snowboard helmets come in great colors and designs.

I admit I have been tempted by appearance more than once.

Today, I care much more about:

• Safety certification.
• Comfortable fit.
• Good ventilation.
• Goggle compatibility.
• Reliable adjustment system.

The best-looking helmet is not always the one that feels best after six hours on the mountain.

These small lessons have completely changed the way I shop for snowboard helmets. Instead of hoping a helmet will fit, I now know exactly what to measure, what to check, and what mistakes to avoid. That confidence makes every purchase much easier and helps me focus on enjoying the ride instead of adjusting my helmet all day.

Extra Tips Before Buying a Snowboard Helmet

Measuring your head is the first step, but it is not the only thing I check before buying a snowboard helmet. Over the years, I have learned that a few extra details can make the difference between a helmet that feels good for ten minutes and one that stays comfortable all day.

I usually spend a little extra time comparing helmets before making my final decision. It may seem unnecessary when several models fit well, but those small differences become obvious after a full day on the mountain. Comfort, ventilation, and safety features matter just as much as the size printed on the label.

Choose Safety Before Style

I enjoy a clean-looking helmet as much as anyone else, but appearance is never my first priority.

The helmet’s main job is to protect your head during a fall. A stylish design is simply a bonus.

When I compare helmets, I always look for:

• ASTM F2040 certification
• CE EN1077 certification
• MIPS or another rotational impact protection system
• Strong outer shell construction
• High-density EPS foam liner

These features give me confidence that the helmet has been designed and tested for snow sports.

Look for Good Ventilation

I used to think ventilation only mattered on warm spring days.

Then I spent an entire afternoon riding in Utah under bright sunshine. Even though the air was cold, I started sweating during every long traverse and hike-to section.

A helmet with good airflow helped much more than I expected.

I now look for features like:

• Adjustable air vents
• Front intake vents
• Rear exhaust vents
• Moisture-wicking liner
• Breathable ear pads

These features help regulate temperature and reduce moisture inside the helmet.

Make Sure the Adjustment Dial Works Smoothly

Most modern snowboard helmets include a fit adjustment dial at the back.

I always test it several times before buying.

A good adjustment system should:

• Turn smoothly
• Tighten evenly
• Stay secure while riding
• Be easy to adjust with gloves on

The dial should fine-tune the fit, not compensate for buying the wrong size.

Wear Your Goggles During the Fitting

This has become one of my personal rules.

Whenever I shop in a store, I bring my snowboard goggles with me.

Trying both together helps me check for:

• Comfortable forehead contact
• No visible gap
• Secure goggle strap position
• Wide field of vision
• No pressure around my nose

A helmet and goggles should work as one system. If they do not fit together properly, I keep looking.

Think About Your Riding Style

Every snowboarder rides differently.

That is why I never recommend buying a helmet based only on someone else’s opinion.

I ask myself a few simple questions.

• Do I spend most of my time on groomed runs?
• Do I enjoy terrain parks?
• Do I ride in deep powder?
• Do I travel to colder mountain resorts?
• Will I wear the helmet for long days?

Answering those questions helps me choose a helmet with the right balance of ventilation, warmth, and protection.

Don’t Ignore Comfort

One lesson took me several seasons to learn.

A helmet that is technically safe but uncomfortable will probably spend more time hanging on your gear rack than protecting your head.

Whenever I try on a new helmet, I wear it for at least ten minutes.

If I notice:

• Pressure on my forehead
• Tightness near my temples
• Uneven padding
• Constant adjustment

I move on to another model.

Comfort encourages me to keep the helmet on all day, and that is exactly where it belongs.

Final Thoughts

When someone asks me how to measure for snowboard helmet, I always tell them that the measuring tape is only the beginning.

Learning my exact head size completely changed the way I shop for helmets. Before that, I relied on guesswork, size labels, and online reviews. Sometimes I got lucky, but more often I ended up with a helmet that never felt quite right.

Now my process is simple.

I measure my head carefully, compare the number with the manufacturer’s size chart, and always check the overall fit before making a final decision. I also test the helmet with my goggles, wear it for several minutes, and pay attention to any pressure points.

That extra effort has been worth it every single time.

Whether I am snowboarding in Colorado, enjoying fresh powder in Utah, or taking a weekend trip to Vermont, I know my helmet fits the way it should. It stays comfortable on long chairlift rides, remains secure during fast descents, and gives me confidence to focus on the mountain instead of constantly adjusting my gear.

If there is one lesson I hope you take away from this guide, it is this: never guess your snowboard helmet size. Spend a few minutes measuring your head, use the brand’s sizing chart, and choose a helmet that fits both your head and your riding style.

A properly fitted snowboard helmet is one of the simplest investments you can make for a safer and more enjoyable day on the snow.

Frequently Asked Questions

How do I measure for a snowboard helmet?

Use a flexible measuring tape and wrap it around the widest part of your head, about one inch above your eyebrows. Measure in centimeters and compare the number with the helmet brand’s sizing chart for the most accurate fit.

Should a snowboard helmet feel tight?

A snowboard helmet should feel snug but not painful. It should touch your head evenly without creating pressure points, headaches, or discomfort after wearing it for several minutes.

Can I wear a beanie under my snowboard helmet?

A thick beanie is not recommended because it can change the fit and reduce stability. A thin helmet liner or lightweight balaclava is a much better option for extra warmth.

What happens if my snowboard helmet is too big?

A helmet that is too large can move during a fall, reducing its ability to protect your head. It may also slide over your eyes, shift from side to side, or leave gaps around your goggles.

Do all snowboard helmet brands fit the same?

No. Every manufacturer uses slightly different shell shapes, padding, and sizing charts. Even if you wear a medium in one brand, you should always measure your head and check the specific size guide before buying another helmet.
