How to fit a bike helmet for a child like a pro

Riding a bike is a fun activity and a great way to get some exercise. It is also an excellent opportunity to bond with your child. While it is an enjoyable pastime, safety must always be a top priority, especially when it comes to children. A helmet is an essential safety equipment for biking, protecting the head from potential injuries. Properly fitting a bike helmet is crucial to ensure that it offers maximum protection to your child.

Why is a properly fitting bike helmet important?

Fitting your child’s helmet correctly is essential for their safety. A poorly fitting helmet is as good as not having one at all, as it will not adequately protect your child’s head in case of an accident. A well-fitted helmet will absorb the shock and reduce the impact, which will lower the risk of injury. Children’s heads are delicate and are still in the development stage, making them more vulnerable to head injuries. Injuries sustained at a young age could have significant implications on their long-term health.

When should my child wear a bike helmet?

Your child should wear a bike helmet whenever they are riding a bike, scooter, skateboard or any other activity that involves wheels. It is a good idea to make it a rule that your child wears a helmet anytime they are on wheels, even for short distances or when playing. Children learn from their parents, so leading by example and wearing a helmet yourself sends the right message about bike safety.

How to measure your child’s head for a helmet?

Knowing your child’s head circumference and shape is crucial when buying a helmet. Take a measuring tape and measure the head’s widest part, which is usually above the eyebrows and ears. Measure two or three times to get accurate measurements. Helmets come with manufacturer size guides, so compare your child’s head circumference with the helmet size guide to find the appropriate size. If your child is between sizes, choose the larger size.

What if my child’s head shape doesn’t match the helmet’s shape?

Different helmets fit differently because of varying shapes and sizes. After measuring the widest part of your child’s head, consider the helmet’s shape. Some helmets are more circular shaped, while others are more oval. If your child’s head is more round-shaped, select a helmet that is also round-shaped, and vice versa. Ensure you try on several helmets to find the best fit for your child.

How to fit the helmet properly

Step 1: Position the helmet correctly

The helmet should sit squarely on the head and cover the forehead to offer maximum protection in case of a fall. Adjust the helmet so that the front edge is just above the eyebrows, leaving no space between the helmet and the forehead. The side straps should be in a ‘V’ shape around the ears, with the straps centered under the ears’ bottom. The chinstrap should be snug and flat against the chin, and it should not be too tight or too loose.

Step 2: Adjust the straps correctly

Adjust the chinstrap first, making sure it fits snugly against the chin. The strap should fit tightly against the skin and leave no gaps. Tighten the side straps, making sure the ‘V’ shape sits securely around the ears. Adjust the sliding buckle to ensure the straps are not too tight or too loose.

Step 3: Check the fit

Check that the helmet fits snugly and does not move around or wobble when the child shakes their head. The helmet should stay comfortably in place without slipping or tilting forward or backward. The most common mistake when fitting a helmet is making it too loose, so ensure it fits snugly, but not excessively tight.

How to make sure the helmet is comfortable

If your child is comfortable wearing their helmet, they are more likely to wear it consistently. A comfortable helmet should feel snug and secure without being overly tight or causing any discomfort. Consider the following factors when determining whether a helmet is comfortable:

  • The helmet should not cause any pressure points or rub against the child’s skin
  • Ensure that the helmet has enough ventilation to reduce heat buildup on the head
  • Choose a helmet that is lightweight and does not feel cumbersome or heavy.
  • Find a helmet with adjustable straps to modify the fit and ensure comfort

When should I replace my child’s helmet?

While helmets are built to last, they should be replaced after any significant impact or after following the manufacturer’s guidelines for regular wear and tear. A helmet that has been in an accident or been dropped from a height should not be used again, even if there is no visible damage. It is generally recommended to replace a helmet every five years, even if it has never been in an accident.


A properly fitted helmet is essential for protecting your child’s head while biking or being on wheels. Make sure to measure your child’s head and choose a helmet with the right size and shape. Follow the manufacturer’s guidelines on how to fit the helmet correctly, and remember to check for comfort. Always lead by example and make wearing a helmet a rule when your child is on wheels. Remember to replace helmets following significant impacts or regular wear and tear.
