In our daily life, biking is a fantastic way to stay active and enjoy the outdoors, but safety should always be a top priority. So, it is necessary to ensure your bike helmet fits correctly for maximum protection during accidents. A poorly fitted helmet can be both uncomfortable and unsafe. In this guide, we'll share several effective steps to find the right size for your road bike or mountain bike helmet, providing you with a secure and comfortable fit.

How are helmets sized?

Bike helmets have various sizes, with some offering a one-size-fits-all design, while others have a range of sizes. Brands use different size notations, such as numerical values, words, or small/medium/large scales. It's essential to check the manufacturer's size chart and choose the appropriate size based on your head circumference. Most bicycle helmets have adjustable cradles to fit various head sizes, and they can vary in shape from one brand to another.

How to measure your head for a helmet

If you want to find the right helmet size, you need to measure your head just above your eyebrows and ears. And also, it’s necessary to use a flexible fabric tape measure or a string to get an accurate measurement. The fit of the helmet should be snug but not constricting. Avoid using a metal tape measure, as it won't provide an accurate measurement for the curves of your head.

How to adjust the fit of a helmet

Once you have the right size helmet, minimal adjustment should be required. Place the helmet above your eyebrows and ears and adjust the cradle using the dial at the rear. The chin strap should be snug but not too tight. If your helmet comes with replaceable padding, try out different options until you find the perfect fit. The helmet should sit securely on your head without any rotation in any direction. So, take a moment to adjust it properly and enjoy your biking adventures with peace of mind!

Does MIPS affect helmet sizing?

MIPS (Multi-Directional Impact Protection System) is a technology that allows the outer shell of the helmet to rotate independently of the cradle, potentially improving safety during impacts. MIPS helmets are often considered among the safest. The integration of MIPS into helmet design means it no longer significantly affects helmet sizing. A small amount of movement might be felt, but this is confined to the outer shell and won't impact the cradle's fit.

Can I have a ponytail or wear a hat with a helmet?

Getting a perfect fit with your bike helmet is essential for safety, but certain factors can hinder that, with a ponytail being one of the most common culprits. While some helmets are made with a large exit port at the back to accommodate ponytails, others might not be suitable for this hairstyle. In such cases, you might need to adjust your hair or opt for a helmet that is designed to work with ponytails.

If you prefer wearing thin hats or cycling caps, you can do so under your helmet without affecting the fit. These accessories won't cause any issues as long as they don't alter the helmet's position on your head.

However, it's crucial to avoid wearing a beanie or hood under your helmet for safety reasons. The extra thickness can impact the fit and may compromise the helmet's ability to protect you effectively.

Remember, finding the right helmet fit ensures your safety while cycling, so make adjustments as needed and choose the appropriate helmet to suit your hairstyle. Safety should always come first!

How to choose the right size kids' bike helmet

When it comes to kids' bike helmets, a proper fit is crucial as they grow. Thus, as parents, you need to measure your child's head circumference and check the size range for the specific helmet model. You can also try the helmet before purchase is recommended, as kids might be particular about the fit. It’s important to ensure a close fit that's not too tight using any available adjusters. Once properly fitted, they'll get used to wearing the helmet, ensuring their safety while riding.

Remember, a well-fitted helmet can save lives, so never compromise on safety. Therefore, it is very important to measure your head and adjust the helmet correctly. Only in this way, can you enjoy your bike rides with peace of mind! Stay safe and happy cycling!
