Selecting the Perfect Bike Helmet for Safety and Comfort


When it comes to cycling, prioritizing safety is essential, and a well-fitted bike helmet is a crucial part of your safety gear. Whether you’re an experienced cyclist or a novice, finding the right helmet can be challenging. This bike helmet size guide will simplify the process of choosing and fitting your bike helmet for optimal protection and comfort.

How to measure and find the correct helmet size with Inflabi and Other helmets.

While many budget helmet manufacturers offer a one-size-fits-all design, Inflabi will provide a range of sizes to ensure a secure and comfortable fit. Some manufacturers use a range of head diameters (for example, size 52 to 56cm), while others use a small/medium/large scale.

Understanding the importance of a well-fitted helmet is crucial. A helmet that’s too large can slide around, obstructing your vision and providing inadequate protection. Conversely, a helmet that’s too small can be uncomfortable and may not cover your head adequately, leaving you vulnerable to injury.

Regardless of of you plan to be one of the first to join the Inflabi community or plan on sticking with your traditional helmet. Either way, we have created this guide to help you stay safe!

Step 1: Measure Your Head

The first step in selecting the right helmet size is to measure your head. Here’s how:

  • Use a flexible measuring tape. If you don’t have one, a string measured against a ruler will work.
  • Wrap the tape around your head, about an inch above your eyebrows. This is typically the largest part of the head, and it’s where your helmet will sit.
  • Record the measurement in both inches and centimeters. Different helmet manufacturers may use different units of measurement.

Step 2: Choose the Right Size

Once you have your head measurement, compare it with the sizing chart provided by the helmet manufacturer or reference it against the most popular sizes used amongst brands below. However, please remember, sizes can vary between brands, so it’s essential to check the manufacteurs specific chart for the helmet you’re considering after using this helmet size guide.

Helmet Size Size in CM
Small 50-55
Medium 55-60
Large 58-62
Xtra-Large 62+

Step 3: Try It On

After determining the correct size range, try on several helmets. It’s important to try different brands and models to find one that fits your head shape comfortably. The helmet should sit level on your head and be snug but not too tight. There should be no gaps between the helmet and your head, and the chin strap should fit snugly.

Step 4: Check the Fit

After finding a comfortable helmet, check the fit. The helmet should sit level on your head, with the front just above your eyebrows. The back of the helmet should not touch the nape of your neck, and there should be no gaps between the helmet and your head. The chin strap should fit snugly and securely.

Step 5: Wear It Correctly!

Once you’ve found the right helmet and adjusted it to fit properly, it’s important to wear it correctly. Ensure the chin strap is buckled and adjusted snugly before engaging in any activity. The helmet should sit level on your head and should not move around or shift during activity.

Step 6: Replace It When Necessary

Over time, helmets can become damaged or worn, compromising their effectiveness in protecting your head. Replace your helmet if it has been involved in an impact or if it shows signs of wear and tear. Additionally, helmets should be replaced every 5-10 years, even if they have not been involved in a crash.

By following these steps in our helmet size guide, you can ensure that you are wearing the correct helmet size for your head, providing maximum protection during your activities. Stay safe out there!
