A reliable measurement helps you select sizes to try. Record it carefully, then use the chart for the exact model you are considering.
Prepare the measurement
Use a flexible measuring tape and a mirror, or ask someone to help. Keep hair in a practical riding arrangement. Remove bulky items that would prevent the tape from following the head consistently.
Take repeat readings
Position the tape above the eyebrows and around the fullest part of the back of the head. Keep it level and close to the head. Repeat the reading; if the results differ, check the tape position instead of averaging inconsistent measurements.
Use the correct chart
Compare the result in centimetres with the model’s published size range. If you are between sizes, ask the retailer which candidates to try. Avoid choosing automatically from the size you wore in another brand or a different helmet generation.
Verify before ordering
A measurement does not show how the helmet will contact your head. Arrange a fitting or confirm a suitable unused-item return policy. Record the measured circumference, chart and fitting result together so an online order matches the item you tried.
