Helmet size and fit chart
The proper fit of a helmet is vital to the performance of a helmet during an impact.
The best possible protection in the event of a fall or accident can only be assured if your helmet is the correct size.
The best possible protection in the event of a fall or accident can only be assured if your helmet is the correct size. For maximum protection, the helmet must fit correctly with the chin strap securely fastened and provide adequate peripheral vision.
Follow the steps below to determine the correct helmet for you:
- Measure your head size with a tape.
- Determine the right helmet size.
- Check that the helmet fits you correctly.
1. Measure your head size.
Measuring the head is only a starting point. Due to variation in shapes, heads that are apparently the same size when measured with a tape may not necessarily fit the same size helmet. The circumference of the head should be measured at a point approximately one centimetre above the eyebrows at the front and at a point at the back of the head that results in the largest possible measurement.
Take several measurements. The largest measurement is the one you should consider first. If you wear a balaclava or balaclava for your head, always measure and fit the helmet with it on.
When fitted correctly, the helmet should be worn low on the brow, eyes near the centre of the eye opening, resting on the top of the head with an even, firm pressure all around, tight without excessive pressure points.

Use a flexible sewing tape and ask a friend or family member to help you take the most accurate measurements. Add one centimetre to the measurement taken.
2. Determine the correct helmet size according to the brand.

3. Check that the helmet fits correctly.
Check that the helmet fits correctly.
With the helmet on and the chin strap fastened and correctly adjusted, check that the helmet is your size and fits correctly.
Step 1:
Check that all the pads inside the helmet are in firm contact with your head but do not put undue pressure on the head pads, cheek pads and forehead pads.
Step 2:
With the helmet on, hold it firmly between both hands and move it up and down. Try to rotate the helmet.
These movements should make you feel the skin on your face and scalp move as the helmet moves. If the helmet moves too easily, the helmet is too big.
Step 3:
With the helmet on, grab it by the chin strap and try to pull it backwards off your head. If you can do this, the helmet is either too big or the chin strap is too loose.
Step 4:
Grip the back of the helmet with both hands and try to rotate it forward on your head.
If you can remove the helmet from your head in this way, the chin strap is too loose or the helmet is too large. Readjust the chin strap or, if necessary, select a smaller helmet size.
