A motorcycle helmet is one of the most important pieces of equipment you can buy. A good motorcycle helmet is a style statement and an investment in yourself.
Take picking a helmet seriously. Find one that’s not only stylish but fits properly, too. A great-fitting helmet is essential for protection, comfort, and performance.
Knowing how to measure a motorcycle helmet is a critical part of the shopping experience. With this guide, you’ll learn how to choose the right size helmet, how it should fit, and why visiting a dealer can help you make an informed choice about this all-important piece of headgear.
Knowing how to measure your head for a motorcycle helmet is important for many reasons. It’s about having maximum protection each time you hit the road. A properly fitted helmet also improves comfort and helps reduce rider fatigue, but the most important factor is that an ill-fitting helmet can put you at risk of serious injury.
Before committing to a new motorcycle helmet, you should recognize the signs of a bad fit. Helmets that don’t fit properly won’t offer the protection and, comfort, and stability you need on the road. Watch out for the following signs that your new helmet won’t fit.
Your helmet might be too loose if:
On the other hand, a helmet that’s too tight might have the following issues:
Your helmet’s chin strap should be secure and comfortable with minimal slack. The helmet itself shouldn’t tilt forward or backward. If you feel dizziness after wearing it for a short period, it’s not a good fit.
Once you know what type of helmet suits your riding style and needs, it’s time to work on finding the right fit. Taking accurate measurements helps you choose the right size helmet, regardless of brand or style preferences.
Measuring your head for a motorcycle helmet is easy with the right tools. If you can’t visit a dealership or plan to buy online, grab the following:
If you don’t have a soft measuring tape, you can substitute a string and a ruler. Wrap the string around your head and mark the length you'll measure with the ruler.
Grab your measuring tape, mirror, and pen and paper.
Find the widest part of your head. Place the measuring tape about an inch above your eyebrows. Make sure the tape sits just above your ears and wraps evenly around the back of your head, right at the largest point.
Measure your head circumference. Hold the tape snug but not too tight. Note the measurement in both inches and centimeters.
Double-check your measurement. Measure at least twice. If your numbers vary slightly, use the larger number.
Compare your helmet with motorcycle helmet size charts.
Measuring your head size accurately makes it easier to find the right helmet for protection and comfort.
With your head size measurement in hand, the next step is matching your measurement to the correct helmet size. But it’s not that simple. Helmet sizes can vary between manufacturers and styles, so relying on a single “medium” or “large” label isn’t enough. Instead, compare your measurement to the specific brand’s size chart.
Why do size charts matter? Each helmet brand designs its shells and interior padding differently, meaning one brand’s “medium” might fit like a “small” in another. Always check the official size chart before you buy.
While online measurements help narrow your options, experiencing a helmet firsthand at your local dealership offers unmatched benefits. Dealership experts provide personalized guidance, accurate measurements, and ensure you leave with the perfect helmet for your needs. For the best experience and fit, visit your dealership and:
Plus, when you purchase at the dealership, you’ll benefit from immediate expert adjustments and the peace of mind that comes with personalized service.
Try a smaller size if there’s space between your brow line and the inner lining – or you can roll the helmet forward or off your head. Your skin and scalp should move as the helmet moves. It should fit as tightly as you can comfortably wear it.
If the helmet becomes uncomfortable, try another size, a different helmet, or a different shell style. Remember to wear eyewear or options like a sun shield while trying on the helmet, especially if they’re a regular part of your rides.
Once you’ve found a helmet that fits well, ensure no part of the helmet obstructs your field of vision to help ensure a functional, comfortable ride.

A helmet should fit snugly, but it shouldn’t cause pain or create pressure points. Helmets shouldn’t move when you shake your head, but it also shouldn’t be so tight that it leaves marks or discomfort.
You can, but it’s best to measure your head first and check the manufacturer’s size chart. Carefully review the return policy if buying a helmet online so you can exchange sizes if needed.
In most cases, you should choose the smaller size as the padding will break in over time. If it’s uncomfortably tight, look for adjustable padding or consider a different model that fits your head shape better.
Use a soft measuring tape or a string and a ruler to measure your head circumference. Use a mirror to ensure you’re measuring the right part of your head. Write down the numbers in inches and centimeters.
It should be snug with even pressure all around your head. The helmet shouldn’t shift when you move. Cheek pads should press lightly. If it moves easily, it’s too big.
Yes, but use a mirror or ask a friend to help if possible. It can give you a more accurate measurement. If you’re measuring alone, double-check the numbers to avoid sizing mistakes.
Measuring too high or too low on your head can give you an incorrect measurement. You should always measure at the widest part of your head, about one inch above your eyebrows.
Measure your head before you buy a new helmet, especially if you’re switching brands. If you’ve had significant weight loss, or hair changes, or haven’t checked in a few years, remeasure to ensure the best fit.
