If your child is interested in riding a motorcycle or ATV, it’s important to prioritize safety by choosing the right helmet. One of the most critical factors to consider when selecting a helmet is its size. In this article, we’ll provide you with a comprehensive children’s motorcycle helmet size chart, so you can ensure your child’s helmet fits correctly and keeps them safe while riding.

Why Proper Helmet Fit is Important

Before we dive into the size chart, let’s first discuss why proper helmet fit is essential. A helmet that doesn’t fit correctly won’t provide adequate protection in the event of an accident. Here are some common problems that can arise from an ill-fitting helmet:

  • The helmet is too loose, which can cause it to shift or fall off during an impact.
  • The helmet is too tight, which can cause discomfort and headaches, and may prevent the chin strap from fitting properly.
  • The helmet doesn’t cover the forehead or back of the head, leaving those areas vulnerable to injury.

To ensure your child’s helmet provides optimal protection, it’s crucial to choose the correct size. Let’s take a look at the children’s motorcycle helmet size chart to help you find the right fit.

Tips for Ensuring Proper Helmet Fit

While the size chart provides a helpful starting point, it’s essential to also consider the following factors to ensure your child’s helmet fits correctly:

1. Try Before You Buy

Before purchasing a helmet, take your child to a motorcycle or ATV shop and have them try on different helmets. This will give you a better sense of the fit and comfort of each helmet, and allow you to make an informed decision.

2. Check the Chin Strap

The chin strap should fit snugly against your child’s chin, with no more than one finger’s width of space between the strap and their skin. Make sure the strap is properly fastened and that your child can’t easily remove the helmet.

3. Check the Padding

The padding inside the helmet should be snug against your child’s head, with no gaps or spaces. If the padding is loose or moves around, the helmet may not fit properly.

4. Check the Visibility

Ensure the helmet doesn’t obstruct your child’s vision or hearing, as this could compromise their safety while riding.

5. Check for Wear and Tear

Inspect the helmet regularly for any signs of wear or damage, such as cracks, dents, or scratches. If you notice any damage, it’s time to replace the helmet.

6. Consider the Type of Riding

Different types of riding may require different types of helmets. For example, off-road riding may require a helmet with a face shield to protect against debris, while street riding may not. Consider the type of riding your child will be doing when selecting a helmet.

7. Replace the Helmet When Necessary

Helmets should be replaced every five years or after an impact, even if there is no visible damage. Over time, the foam padding in the helmet can break down, reducing its effectiveness in protecting your child.


What if my child’s head measurement falls between two sizes on the chart?

In this case, it’s best to go with the larger size to ensure a comfortable and secure fit.

Can I use an adult helmet for my child?

No, it’s essential to use a helmet specifically designed for children, as adult helmets won’t fit properly and won’t provide adequate protection.

Can I buy a used helmet for my child?

It’s not recommended to purchase a used helmet, as it may have already been involved in an impact, reducing its effectiveness in protecting your child.

What if my child grows out of their helmet?

It’s important to replace the helmet with a larger size as soon as possible to ensure continued protection.

Are all helmets created equal?

No, different helmets may have different safety ratings and features. Look for helmets that meet or exceed safety standards, such as DOT or Snell certification.


Choosing the right size helmet is crucial to ensuring your child’s safety while riding a motorcycle or ATV. Use the children’s motorcycle helmet size chart and the tips provided in this article to find the perfect helmet for your child. Remember to prioritize safety and always replace the helmet when necessary.
