Importance of a Properly Fitted Helmet

Before diving into the measuring process, it’s essential to understand why a properly fitted helmet is so crucial. A helmet that fits correctly provides maximum protection against head injuries and reduces the risk of severe trauma during accidents. Additionally, a comfortable helmet that sits securely on your head enhances your riding experience, allowing you to concentrate better and enjoy the open road with peace of mind.

Tools You’ll Need

To measure for a motorcycle helmet accurately, you’ll need a flexible measuring tape or a piece of string and a ruler. These tools will enable you to obtain precise measurements for an optimal fit.

Measuring Your Head

To get started, follow these steps to measure your head accurately:


Begin by pulling your hair back to expose your forehead and the base of your skull. If you have long hair, consider tying it back in a ponytail to prevent interference during the measuring process.

Measuring Tape:

Take your measuring tape or string and wrap it around the widest part of your head. Ensure that the tape sits just above your eyebrows and ears, maintaining a level position all the way around. Make sure the tape is not too tight or too loose, as this can lead to inaccurate measurements.

Obtaining the Measurement:

Once the tape is securely positioned, take note of the circumference measurement. If you’re using a string, mark the point where it meets and measure the length against a ruler. This measurement will help you determine the helmet size that best fits your head.

Choosing the Right Helmet Size

Motorcycle helmets come in various sizes, typically ranging from extra small (XS) to extra large (XL). The measurement you obtained from the previous step will help you select the appropriate size. Refer to the manufacturer’s sizing chart, which is often available on their website or product packaging, to find the helmet size that corresponds to your head circumference.

Additional Considerations

While measuring your head circumference is crucial for choosing the right helmet size, it’s important to consider other factors to ensure a perfect fit. These include:

Helmet Shape: 

Different helmet manufacturers design their helmets with varying head shapes in mind. Some helmets are rounder, while others are more oval-shaped. Try on different helmets to find the one that matches your head shape and provides a snug fit without uncomfortable pressure points.

Helmet Retention System: 

Pay attention to the helmet’s retention system, which typically includes chin straps and quick-release buckles. Ensure that the straps can be adjusted to fit comfortably under your chin, providing a secure and snug fit.

Helmet Fitment Test: 

Once you’ve chosen a helmet, wear it for a few minutes to assess its fit. The helmet should feel snug but not overly tight, with no pressure points or excessive movement when you shake your head or move your jaw. Perform a fitment test by gently moving the helmet up and down, left and right, to ensure it stays in place during riding.


Why is it important to measure for a motorcycle helmet?

Measuring for a motorcycle helmet is vital because it ensures a proper fit, which is crucial for your safety and comfort while riding. A helmet that is too loose may come off during an accident, while one that is too tight can cause discomfort and distract you from focusing on the road. By measuring your head accurately, you can select a helmet size that provides optimal protection and enhances your riding experience.

Can I use a regular tape measure to measure for a motorcycle helmet?

Yes, you can use a regular flexible measuring tape to measure for a motorcycle helmet. Alternatively, if you don’t have a measuring tape, you can use a piece of string and a ruler. Wrap the measuring tape or string around the widest part of your head, just above your eyebrows and ears. Ensure it’s level and not too tight or too loose. The measurement you obtain will help you determine the helmet size that suits you best.

How do I choose the right helmet size based on my head measurement?

Once you have measured your head circumference, refer to the manufacturer’s sizing chart to select the appropriate helmet size. The sizing chart will typically be available on the manufacturer’s website or product packaging. Compare your head measurement with the corresponding size on the chart. Keep in mind that different helmet brands may have slightly different sizing guidelines, so it’s essential to refer to the specific manufacturer’s recommendations for the most accurate fit.


Measuring for a motorcycle helmet is a crucial step in ensuring your safety and comfort on the road. By accurately measuring your head and considering additional factors like helmet shape and retention system, you can find the perfect helmet that provides optimal protection and enhances your riding experience. Remember, a well-fitted helmet is an investment in your safety that should never be compromised.
