Why Helmet Sizing Matters
Getting the right helmet size is crucial for safety and comfort. A helmet that’s too big won’t protect you properly in an accident. A helmet that’s too small will be uncomfortable and may not provide adequate protection either. A well-fitted helmet is snug, secure, and allows you to focus on the road or trail ahead.
Step 1: Measure Your Head
Before you even think about trying on helmets, you need to measure your head. This will give you a baseline to start with.
What You’ll Need:
- A flexible measuring tape (fabric or plastic)
- A mirror (optional, but helpful)
- A friend (also optional, but can make things easier)
How to Measure:
- Wrap the measuring tape around the largest part of your head. This is usually about a half-inch above your eyebrows and just above your ears.
- Make sure the tape is level all the way around.
- Note the measurement in centimeters or inches. This is your head circumference.
Step 2: Consult a Size Chart
Helmet manufacturers use size charts to translate head circumference into helmet sizes (e.g., Small, Medium, Large). Size charts can vary between brands, so it’s important to consult the specific chart for the helmet you’re interested in. Don’t assume your size is the same across all brands.
Here’s a general example of a helmet sizing chart:
| Size | Head Circumference (cm) | Head Circumference (in) |
|---|---|---|
| Small | 55-56 | 6 7/8 – 7 |
| Medium | 57-58 | 7 1/8 – 7 1/4 |
| Large | 59-60 | 7 3/8 – 7 1/2 |
| X-Large | 61-62 | 7 5/8 – 7 3/4 |
| 2X-Large | 63-64 | 7 7/8 – 8 |
Always refer to the manufacturer’s specific size chart for the most accurate sizing.
Step 3: Try On Helmets
Now comes the crucial part: trying on helmets. Don’t just order a helmet online based on the size chart alone. Whenever possible, visit a shop that carries a wide variety of helmets. This allows you to physically try them on and assess the fit.
What to Look For:
- Snug Fit: The helmet should feel snug all the way around your head, without any pressure points.
- No Movement: When you shake your head, the helmet should move with your head, not independently.
- Eyebrow Test: With the helmet on, try to push it up from the back. If you can easily move the helmet enough to expose your forehead, it’s too big.
- Cheek Pads: The cheek pads should make contact with your cheeks. They should be snug, but not so tight that they’re uncomfortable.
Step 4: The Roll-Off Test
This test helps determine if the helmet will stay in place during an impact.
How to Perform the Roll-Off Test:
- Put the helmet on and fasten the chin strap.
- Have someone try to roll the helmet off your head by pulling upwards and forwards from the back of the helmet.
- If the helmet rolls off, it’s too big or the chin strap isn’t properly adjusted.
Step 5: Adjust the Fit
Many helmets have adjustable features, such as cheek pads, liners, or retention systems. Use these features to fine-tune the fit. A properly adjusted helmet will feel secure and comfortable.
Step 6: Consider the Helmet’s Intended Use
The type of activity you’ll be doing also influences the helmet you choose. A motorcycle helmet will have different features and a different fit than a bicycle helmet. Make sure you’re choosing a helmet designed for your specific activity.
Gap Content: Beyond the Basics
What if I’m Between Sizes?
If you’re between sizes, it’s generally recommended to go with the smaller size. You can always adjust the fit with thinner cheek pads or liners, but you can’t make a helmet smaller if it’s already too big.
How Often Should I Replace My Helmet?
Most manufacturers recommend replacing your helmet every 3-5 years, even if it hasn’t been involved in an accident. The materials in the helmet can degrade over time, reducing its protective capabilities. Always replace your helmet after any impact, even if there’s no visible damage.
Can I Modify My Helmet?
Never modify your helmet in any way. Drilling holes, removing padding, or altering the shell can compromise its structural integrity and reduce its ability to protect you in an accident. Use only manufacturer-approved accessories and replacement parts.
What About Hair?
Consider your hairstyle when sizing a helmet. If you often wear your hair in a bun or ponytail, measure your head with your hair styled that way. Some helmets are designed with features to accommodate ponytails.
The Importance of Professional Fitting
While this guide provides a comprehensive overview, nothing beats a professional fitting at a reputable shop. Experienced staff can assess your head shape, recommend specific helmet models, and ensure a proper fit. Consider a professional fitting an investment in your safety.
