How Can You Tell if You Have a Narrow Head for a Helmet?
Determining whether you have a narrow head for a helmet can be assessed through several key indicators:
- Measurement of Head Width: Use a soft measuring tape to measure the width of your head just above the ears. If the width is significantly less than the average range (typically around 6 to 7 inches), you may have a narrow head.
- Fit of Existing Helmets: Try on various helmet sizes, particularly those marketed for narrow heads. If the helmet feels loose on the sides while fitting well at the front and back, this indicates a narrow head shape.
- Comfort Level: Pay attention to comfort when wearing helmets. If you often experience pressure points on the sides or feel the need to constantly adjust the fit, it could suggest that the helmet is too wide for your narrow head.
- Brand and Model Preferences: Some brands specifically design helmets for narrow head shapes. Research and test these models, as they often feature adjustable systems that cater to a narrower fit.
- Consulting Sizing Charts: Review the sizing charts provided by helmet manufacturers. Many offer detailed measurements that can help you identify if your head size aligns with those recommended for narrow shapes.
Measuring your head width is crucial; a measurement below the standard range indicates a narrow head. Trying on different helmets allows you to gauge which fits best without excessive space at the sides. If you find discomfort or shifting, this could signal a mismatch in helmet width.
Exploring brands that cater to narrower heads can greatly enhance your riding experience, as these helmets are designed with specific contours for improved aerodynamics and comfort. Always refer to sizing charts, as they provide valuable insights into which models accommodate narrower shapes effectively.
