Get the Right Fit: How to Measure for Helmet Size
Importance of Proper Helmet Fit
Ensuring that your helmet fits correctly is crucial for your safety. A well-fitted helmet can effectively protect your head in the event of an accident. A loose helmet can come off during a crash, leaving you vulnerable. A too-tight helmet can cause discomfort and even headaches. Moreover, proper helmet fit ensures clear visibility and does not obstruct hearing. It also helps in maintaining stability at high speeds. This is why knowing how to measure for helmet size is important. It’s not just about comfort, but also about safety and performance.
To get the full benefits, one must understand the importance of proper helmet fit. Let’s delve into the different types of helmets and size standards to further this understanding.
Different Types of Helmets and Size Standards
When learning how to measure for helmet size, it’s vital to recognize that helmets come in various shapes and sizes, each designed for specific activities and standards. Here is a brief overview of the common types of helmets and their sizing norms.
Full Face Helmets
These helmets cover the entire head and face, offering the most protection. They’re commonly used for motorsports and high-speed biking. Sizing varies by brand but often ranges from extra-small to extra-large.
Open Face Helmets
Open face or ‘three-quarters’ helmets cover the top and back of the head but not the face. They are popular with urban bikers and cruisers. Their size chart is similar to full face helmets.
Half Helmets
Half helmets protect the top of the head only. They provide the least protection but the greatest freedom and airflow. Size standards for these helmets typically match those of open face helmets.
Off-road Helmets
Built for dirt biking and motocross, off-road helmets have an elongated chin and visor areas for extra protection from debris. They follow a unique sizing guide which is specific to the brand.
Modular Helmets
These are a hybrid between full face and open face helmets, with a movable chin bar. Sizing for modular helmets is based on the full-face model.
Sizing Standards
Helmet sizes are generally measured in centimeters and categorized by letters (XS, S, M, L, XL, XXL). However, it’s important to note that each brand may have its own specific size chart. Always refer to the manufacturer’s sizing guide when selecting a helmet.
It is crucial to understand the differences in types and sizes to choose the right helmet. In the next sections, we’ll cover the tools you’ll need and provide a step-by-step guide on how to measure for your helmet size.
Tools Needed for Measuring Helmet Size
Before you begin the process of measuring your head for a helmet, you need to gather a few tools. These are simple and likely already at your disposal:
- Soft measuring tape: This is crucial for getting an accurate measurement of your head’s circumference. A cloth tape measure can contour to your head better than a rigid one.
- Mirror: A mirror will help you ensure that the tape measure is level and positioned correctly as you measure.
- Piece of string (optional): If you don’t have a soft measuring tape, you can use a string then measure it against a ruler or a metal tape measure.
- Ruler or metal tape measure (if using string): To use in conjunction with the string to find out your head size in centimeters.
- Pen and paper: To note down the measurements once you take them.
Remember, accuracy is key when it comes to how to measure for helmet size. These tools will help you achieve just that, ensuring you’re well on your way to finding a helmet that fits perfectly.
Step-by-Step Guide to Measuring Your Head
When you’re ready to measure your head for a helmet, follow this simple guide to ensure accuracy and a good fit:
- Find the Widest Part of Your Head: Starting above your eyebrows, wrap the soft measuring tape around the back of your head. Make sure it goes over the widest part.
- Keep the Tape Level: Adjust the tape until it’s level all around. Use a mirror to check. The tape should sit snugly, but not too tight.
- Read the Measurement: Once the tape measure is in place, take note of the measurement where the tape overlaps. This is your head’s circumference.
- Write it Down: Immediately after measuring, jot down the number. This prevents forgetting or mixing up numbers.
- Double-Check: Measure at least twice to ensure that you’ve got the right measurement. If you get two different numbers, try again.
- Use a String If Needed: No soft tape? Wrap a string around your head, then measure it against a ruler.
Follow these steps on how to measure for helmet size, and you’ll be well on your way to a helmet that fits just right. Having the correct helmet size is crucial for comfort and safety. It’s worth taking the time to measure properly. With your measurement in hand, you’re now ready to understand helmet shapes and find the ideal helmet for you.
Understanding Helmet Shapes and Why They Matter
Choosing the right helmet involves more than just measurement. Helmet shape is as important as size. Head shapes can vary greatly, typically falling into three categories: round oval, intermediate oval, and long oval. Matching your head shape to the helmet’s internal shape is fundamental. If the helmet does not align with your head shape, discomfort and pressure points may occur.
Round oval helmets fit heads which are equally long and wide. Intermediate oval is the most common shape, being slightly longer than it is wide. Those with a noticeably longer front-to-back measurement would need a long oval helmet.
Here’s why helmet shape matters:
- Comfort: A helmet that matches your head shape feels better to wear.
- Safety: Proper fit ensures maximum protection during impacts.
- Stability: A well-fitting helmet stays secure at high speeds and reduces lift.
To determine your head shape, ask someone to look at the head’s shape from above. You can compare this to a helmet’s internal padding shape. Manufacturers often provide this information. When you know your head shape, you can make a more informed choice. Remember, never compromise on fit. A helmet that fits well in terms of both size and shape will offer the best protection and comfort while riding.
Interpreting the Measurement and Selecting the Right Helmet
After measuring your head, it’s time to interpret those numbers and select the right helmet. Here’s how to move from measurement to the perfect helmet:
- Consult Size Charts: Each helmet brand has a unique size chart. Compare your measurement with their charts.
- Consider Helmet Shape: Your head shape should guide your helmet choice. Round, intermediate, or long oval – pick accordingly.
- Size Up If Necessary: If you’re in between sizes, it’s often safer to size up rather than down.
- Seek Comfortable Fit: The helmet should sit snugly on your head without causing pressure.
- Account for Hairstyle: If you have thick hair or a particular hairstyle, factor that into your size decision.
- Check Return Policies: Ensure the brand offers returns. This makes it risk-free if the helmet doesn’t fit right.
Remember, the right helmet is the one that matches both your head size and shape. It should fit comfortably and securely without putting undue pressure on any area of your head.
Tips for Trying on Helmets
Once you have your head measurement, it’s crucial to try on various helmets. Here are some tips for trying on helmets to ensure the best fit:
- Try Different Brands: Helmet sizes can vary across brands. Always try different ones.
- Wear It for a While: Wear the helmet for at least 5 minutes to catch any discomfort.
- Check for Movement: Shake your head. A good fit means slight movement only.
- Ensure Visibility: Your vision should be clear, without any blockage from the helmet.
- Listen for Gaps: There shouldn’t be spaces between your head and the helmet padding.
- Test the Strap: The strap must be easy to buckle and provide a snug fit.
A helmet that seems good at first glance may not always be comfortable long-term. Spend the time to make sure it’s the right one. With the tips above, you can find a helmet that offers both safety and comfort.
Adjusting the Helmet for Optimal Comfort and Safety
Once you have your helmet, adjustments are key to ensure ideal comfort and safety. Here’s how you can fine-tune your helmet for the best experience:
- Check the Pads: Helmet pads should sit flush against your head. Make sure there are no gaps or pressure points. If there are, you may need to adjust the padding or consider different thickness options.
- Fasten the Chin Strap: The chin strap must be tight enough that you can only fit one or two fingers between it and your jaw. It should not pinch or feel uncomfortable.
- Tighten the Retention System: Many helmets have a dial or a buckle at the back. Use it to secure the helmet so that it does not wobble or tip.
- Move Your Head: After adjustments, move your head up and down, side to side. The helmet should stay in place and not slide over your eyes or off the back of your head.
- Wear Proper Eyewear: If you use glasses or sunglasses, put them on to check for fit. The helmet should not push them down or cause discomfort.
- Consider Ear Space: Ensure there is enough room around your ears. The helmet should not squash them, which can be uncomfortable over time.
By following these steps on how to measure for helmet size and making proper adjustments, you can ride with the confidence that your helmet is optimized for both comfort and safety. Remember, a well-fitting helmet is as critical to your riding experience as it is to your safety on the road.
