How to Measure Your Child For The Perfect Fitting Karting Helmet

Ensuring optimal safety for young motorsport enthusiasts begins with selecting the right-sized karting helmet. While any helmet is better than none, a poorly fitting helmet can compromise protection, among many other things. In this guide, you’ll learn the specifics of measuring and judging the size of a child’s karting helmet, focusing on Zamp Helmets for a tailored fit that maximises safety on the track.

The Importance of Proper Helmet Size

In motorsport, a helmet’s effectiveness is directly linked to its size. The primary purpose of a karting helmet is, of course, to provide protection in case of accidents or impacts. A well-fitted helmet ensures that it stays securely in place during high-speed racing or sudden stops, reducing the risk of head injuries.

An appropriately fitting helmet also ensures maximum visibility during racing i.e. correct visor placement and no slipping of the helmet over the drivers’ eyes, meaning that not only is it paramount for safety, but for comfort and therefore performance and outcome too.

Measuring for the Perfect Fit

Measuring your child’s head accurately for a karting helmet involves a few precise steps to ensure a snug and protective fit:

  1. Grab a fabric measuring tape or a piece of string and a ruler/tape measure
  2. Ensure your child is comfortable and sitting or standing in a relaxed position
  3. Position the Measuring Tape or String:
    • For the fabric measuring tape: Place it around the head approx. one inch (2.54 cm) above the eyebrows, encircling the widest part of the head.
    • For the string: Wrap it around the head in the same manner, making sure it is level and snug but not too tight.
  4. Take the Measurement:
    • If using a fabric measuring tape, read the measurement directly from the tape.
    • If using a string, mark or cut the point where the two ends meet and then straighten it out next to a ruler or tape measure to determine the circumference.
  5. Double-check the measurement to ensure accuracy. It’s crucial to have a precise measurement for selecting the right-sized karting helmet.
  6. Refer to the sizing chart: Karting helmet manufacturers typically provide sizing charts for each helmet model. Consult the sizing chart provided by the specific helmet brand, such as Zamp Helmets, to determine the appropriate size for your child’s head.


Equipping yourself with the knowledge needed to choose the perfect Zamp Helmet for your child allows you to prioritise safety without compromising comfort. Not only does this ensure your child’s safety, but it also allows them to perform at their very best because they are comfortable and confident in their equipment to support them through their racing achievements.
