Wearing a properly fitted motorcycle helmet is critical for safety while riding. An ill-fitting helmet can be uncomfortable and loose, increasing the risk of the helmet coming off in a crash. A helmet that is too tight can cause headaches and discomfort. Taking the time to accurately measure your head and purchase the correct size helmet ensures maximum protection, comfort and proper fit.
Head Shapes and Helmet Fit
Along with head circumference, head shape plays a role in finding the right fitting motorcycle helmet. Helmet interiors are designed with different head shape dimensions in mind. Be aware of your overall head shape to select the helmet shape that will fit best.
The main helmet shape categories are:
- Round Oval: The width and length of the head are nearly equal. Rounds heads are circular rather than elongated.
- Intermediate Oval: The head is slightly longer front to back than side to side. This is the most common head shape.
- Long Oval: The length is considerably longer than the width, giving the head an elongated shape.
- Short Oval: The width is noticeably larger than the length, creating a wider and shorter shape.
Most helmet brands design their models with a head shape in mind. Trying on different shapes and brands is the best way to find your ideal fit. The included sizing pads can also help fine-tune the shape and fit for many helmets.
Importance of Correct Fit
A helmet should fit snugly all around your head to maintain proper protection. However, it should not be painfully tight. General tips for ensuring proper motorcycle helmet fit include:
- The helmet should press firmly on your cheeks and forehead. You should feel the padding pressing slightly.
- There should be no gaps between your brow and the EPS liner at the front.
- Fasten the chin strap and check that the helmet does not shift left or right or front to back.
- Open your mouth wide to make sure the helmet does not press down uncomfortably on your jaw and cheeks.
- Make sure you can comfortably wear your eyeglasses or sunglasses with the helmet on.
- With the chin strap fastened, you should not be able to pull the helmet off your head toward the front. It may come off if you tug sharply upward in the back.
- Do not rely on being able to “break-in” an ill-fitting helmet and make it comfortable over time. Choose a helmet that fits right from the start.
Getting the right fit is key to maximizing protection and avoiding distractions while riding. Take the time to carefully measure and assess the fit according to the tips above. It will be worth it for safety and comfort.
How to Measure Your Head for Motorcycle Helmet Size
Measuring your head properly is the starting point for finding the best fitting motorcycle helmet. Follow these steps using a flexible cloth or paper measuring tape:
1. Wrap the Tape Around Your Head
- Place the tape around the widest part of your head, about 1 inch above your eyebrows and ears.
- Make sure the tape is level from front to back. It should wrap horizontally around your head.
- Keep the tape snug but not overly tight. It should indent the skin slightly.
- For accuracy, have someone else position the tape and read the measurement.
2. Mark Down the Circumference
- Note the circumference measurement where the tape overlaps itself at the end.
- Round the number down to the nearest quarter inch (or nearest centimeter).
- Write down this rounded number to reference when looking at helmet sizes.
3. Take Additional Measurements (Optional)
Some motorcycle helmet brands provide sizing based on additional head measurements beyond basic circumference. Taking these extra measurements can further dial in the fit:
- Front to Back Length: Measure from the center of your forehead to the tip of your occipital bone in back.
- Side to Side Width: Measure across the widest part of your head, above the ear to ear.
- Shape: Assess if your head shape is round, intermediate oval, long oval or short oval.
4. Use the Manufacturer’s Size Chart
Compare your rounded head circumference measurement to the helmet brand’s sizing chart to determine your suggested size. Keep in mind that sizes vary across brands. Refer to the specific brand’s chart rather than a generic one.
5. Try It On for Fit
The ultimate assessment is how the helmet fits your particular head. When trying on helmets in person, make sure to evaluate the fit according to the proper fitting tips outlined above. This will ensure you get the safest, most comfortable motorcycle helmet for your individual needs.

How Do Motorcycle Helmets Fit Compared to Hat Size?
Knowing your standard hat size can provide a starting point for determining your motorcycle helmet size. However, it is not an exact conversion. Helmet fit involves more precise sizing and shaping than typical hats. Use your hat size as a ballpark estimate, not an exact match:
Helmet Size Compared to Hat Size
| Helmet Size | Approximate Hat Size |
|---|---|
| XXS | 6 1/2 to 6 3/4 |
| XS | 6 7/8 to 7 |
| S | 7 1/8 to 7 1/4 |
| M | 7 3/8 to 7 1/2 |
| L | 7 5/8 to 7 3/4 |
| XL | 7 7/8 to 8 |
| XXL | 8 1/8 to 8 1/4 |
These ranges provide an idea, but the motorcycle helmet sizes from specific brands listed above will be the most accurate guides. It is also important to try on helmets in person for fit and shape along the sides and front-to-back. Simply knowing your hat size is not sufficient for choosing a properly fitted helmet. Use the helmet sizing methods outlined in this article to get an exact measurement and fit.

Tips for Getting the Right Fit with a New Helmet (continued)
- Open your mouth wide and make sure the helmet does not press painfully on your jaw and cheeks.

Frequently Asked Questions About Motorcycle Helmet Sizing and Fit!
Here are some common questions about Steph Curry’s traveling history:
How often should you replace your motorcycle helmet?
The recommended replacement interval is 5-7 years from the manufacture date. Helmets should also be replaced after any significant impact, even if no damage is visible. The protective foam materials compress over time, reducing shock absorption. Exposure to sun, heat and chemicals can also degrade materials over the years.
Should a motorcycle helmet be tight?
A helmet should be snug all around your head for proper stability and protection. However, it should not be painfully tight anywhere. It is normal to feel firm padding pressure around your forehead and cheeks. If you feel excessive discomfort or headache pain, the helmet is too small.
How do I know if my motorcycle helmet shape is right?
Assess if the helmet feels evenly pressed around your head, with no gaps or loose spots. Turn your head side to side and nod up and down to check for shifting. Open your mouth wide to prevent chin or jaw pain. Try on helmets with different interior shapes to find the right match for your head’s dimensions.
Can you adjust motorcycle helmet fit?
Many helmets include removable interior padding pieces to slightly customize fit and shape. Thicker pads can improve snugness in loose spots. Thinner pads may relieve pressure points. Some brands offer multiple sizes of these adjustment pads for further fine tuning.
What features help with motorcycle helmet comfort?
Ventilation, removable liners, padded chin straps, face shields, sun visors, aerodynamic designs and lightweight materials can all enhance comfort in a motorcycle helmet. Consider these features in addition to fit when selecting the most comfortable helmet for your needs and riding style.
How do I know if a motorcycle helmet is DOT approved?
Look for a DOT (Department of Transportation) sticker inside the helmet shell. This indicates the helmet meets the minimum federal safety standards required for street use. The manufacturer is required to test and certify compliance with DOT regulations before applying the sticker.
Should I feel air coming into my motorcycle helmet?
A small amount of air flow is normal, especially when riding at higher speeds. The helmet should form a reasonably tight seal all around your head. Excessive wind noise indicates the helmet is too loose. Use the sizing pads to improve the fit if you notice excessive air flow.
Why do some motorcycle helmets cost more than others?
Higher cost helmets typically offer premium features like advanced aerodynamic designs, lighter materials, more interior padding, better ventilation and high-end graphics. While all helmets meet basic safety standards when properly fitted, more expensive models provide added comfort, customization and styling.
