Bicycle Helmets for Big Heads

Understanding the Importance of Proper Helmet Fit

Wearing a bicycle helmet is crucial for protecting your head in the event of an accident. However, a helmet’s effectiveness depends not only on its quality but also on how well it fits. A properly fitted helmet for big heads ensures optimal safety, comfort, and performance. This is particularly important for cyclists with larger head sizes, who may struggle to find suitable helmets that adequately protect them from potential head injuries.

Bicycle helmets for big heads are designed with larger head circumferences in mind, providing ample coverage and comfort without compromising safety. By focusing on essential features such as adjustability, padding, and ventilation, these helmets cater to the unique needs of cyclists with larger head sizes. Properly fitting bicycle helmets significantly reduce the risk of head injuries, making them an indispensable piece of cycling gear for riders of all skill levels.

How to Measure Your Head for the Right Helmet Size

To find the perfect fit for bicycle helmets for big heads, accurate measurement is essential. Start by wrapping a flexible tape measure around your head, just above your eyebrows and at the widest point at the back of your head. This will give you your head circumference, which you can then use to determine the appropriate helmet size.

When measuring, ensure the tape measure is level and snug but not too tight. If you don’t have a flexible tape measure, you can use a piece of string and then measure the length with a ruler or yardstick. Most helmet manufacturers provide size charts on their websites, allowing you to compare your head circumference with their available sizes.

To ensure a proper fit, consider the following tips:

  • Measure your head while wearing any headgear or thick hair you plan to have under the helmet, as this can affect the fit.
  • Always consult the manufacturer’s size chart for the specific helmet model, as sizes can vary between brands.
  • If your head circumference falls between two sizes, choose the larger size, as you can often adjust the fit with internal padding or adjustment systems.

Comfort and Adjustability: Key Features to Consider

When searching for bicycle helmets for big heads, it’s crucial to focus on adjustability, padding, and ventilation to ensure optimal comfort and safety. These features significantly contribute to the overall fit and performance of the helmet, allowing cyclists with larger head sizes to enjoy their rides without worrying about discomfort or safety concerns.


A helmet with a high level of adjustability can accommodate various head shapes and sizes, making it an essential feature for bicycle helmets for big heads. Look for helmets with adjustable fit systems, such as retention systems or dial adjusters, that allow you to fine-tune the fit around your head and under your chin. These systems help distribute pressure evenly, ensuring a snug and secure fit without causing discomfort or pressure points.


Well-designed padding in bicycle helmets for big heads can significantly improve comfort and fit. Look for helmets with removable and washable padding, as this allows you to maintain cleanliness and hygiene. Additionally, consider helmets with thicker padding in areas that come into contact with your head, as this can help absorb sweat and reduce friction, preventing hot spots and discomfort during long rides.


Adequate ventilation is crucial for maintaining comfort during warm or intense rides. Bicycle helmets for big heads should have numerous vents and channels that promote airflow, keeping your head cool and dry. Look for helmets with large vents and deep channeling, as these features can significantly improve ventilation and help prevent overheating.

How to Adjust Your Helmet for a Secure Fit

To ensure a secure and comfortable fit for bicycle helmets for big heads, follow these steps to adjust the fit systems, such as retention systems, dial adjusters, and padding:

  1. Loosen the chinstrap: Before making any adjustments, ensure the chinstrap is loose enough to slide two fingers between your chin and the strap. This allows for comfortable movement while preventing the helmet from shifting during use.
  2. Adjust the retention system: Most helmets feature a dial adjuster at the back that allows you to fine-tune the fit around your head. Turn the dial to tighten or loosen the helmet until it feels snug but comfortable. The helmet should sit level on your head, covering the top of your forehead without obstructing your vision.
  3. Adjust the side straps: The side straps should form a ‘Y’ shape just below your ears. Slide the adjusters on the straps to ensure they meet at this point. If the straps are too loose, the helmet may shift during use, while excessively tight straps can cause discomfort.
  4. Adjust the chinstrap: Once the helmet is properly positioned, tighten the chinstrap so that it’s snug but not too tight. You should be able to fit one or two fingers between your chin and the strap, ensuring a secure fit without causing discomfort.
  5. Check the fit: Perform a fit check by gently moving the helmet from side to side and front to back. The helmet should not shift significantly, and your skin should move slightly with the helmet. If the helmet moves excessively, readjust the fit systems and repeat the fit check.

Remember to periodically re-adjust the helmet fit systems, especially if you wear headgear or thick hair, as these can affect the fit. Regularly checking and adjusting the fit will ensure continued safety and comfort during your cycling adventures.

Additional Considerations for Bicycle Helmet Purchase

When searching for bicycle helmets for big heads, there are several other factors to consider beyond adjustability, padding, and ventilation. These factors include certification standards, style preferences, and compatibility with accessories like headlights and visors. By taking these additional considerations into account, you can ensure a safer, more enjoyable, and personalized cycling experience.

Certification Standards

Always ensure that the helmet you choose meets the required safety standards for your region. In the United States, for example, look for helmets certified by the Consumer Product Safety Commission (CPSC). European standards are regulated by the European Committee for Standardization (CEN), while Australian and New Zealand standards are set by the Australian Standards (AS) organization.

Style Preferences

Bicycle helmets for big heads are available in various styles, colors, and designs, allowing you to choose one that matches your personal taste and preferences. From sleek and minimalist designs to vibrant and eye-catching graphics, there’s a helmet to suit every rider’s style. Consider your preferences and choose a helmet that not only fits well but also looks great and reflects your personality.

Compatibility with Accessories

If you plan to use accessories like headlights, visors, or communication devices with your helmet, ensure that the helmet you choose is compatible with these add-ons. Some helmets come with integrated mounts for accessories, while others may require additional adapters or modifications. Check the manufacturer’s specifications and consult with retailers to ensure compatibility before making a purchase.

Reputable Retailers

Always purchase bicycle helmets for big heads from reputable retailers, either in-store or online. Reputable retailers offer genuine products, warranty support, and knowledgeable customer service. Avoid purchasing from unknown or unverified sources, as counterfeit products may not meet safety standards and could put you at risk during a crash.
