Islabikes guide to fitting a child’s helmet

Helmets that are the wrong size or incorrectly fitted will be uncomfortable to wear and, more importantly, may not protect your child’s head from injury.

Helmets normally come with a fit recommendation in centimetres, covering a range of sizes. This fit measurement relates to the circumference of the head.

To measure your child’s head, follow these simple steps:

  • Take a cloth measuring tape and wrap it around the head about an inch above the eyebrow, making sure the tape is level all the way around.
  • Record the measurement

If you do not have a measuring tape you can use some string instead. Using the string in place of a tape measure, cut it to the circumference of your child’s head, then measure.



How to fit a child’s helmet

Correctly fitting a child’s helmet is a quick and simple process

Step One (Eyes):
Make sure the helmet is facing the right way and that the helmet sits just above the brow, covering your child’s forehead. The brim of the front of the helmet should be about a centimetre above the eyebrows - high enough to not restrict their vision, but low enough to protect their forehead in the event of a fall.

Step Two (Ears):
Make sure the helmet fits securely and does not wobble. First adjust the dial at the back of the helmet until the plastic retention cradle is snug against the head and the helmet does not move side to side or backwards and forwards. You should then adjust the side straps so that they are positioned comfortably in a “V” shape just below each ear.

Step Three (Mouth):
Adjust the chin strap so that it is snug but not restrictive. You should be able to get 2 fingers between the strap and the neck, but no more.

It is also advisable to carry out a quick weekly check to ensure that the helmet has not gone out of adjustment through day-to-day use and the straps have not become twisted.
