Use a tape measure to wrap horizontally around the head, passing over the temples and the back of the head, avoiding the eyes and top of the head

If no tape measure is available, use a string or similar item to measure and then compare to a known length (e.g., ID card length 8.5 cm)

Accurate head circumference measurement is essential for selecting the correct helmet size

Adjust helmet straps so that the buckle sits about one finger width (approximately 1.5 cm) below the ear

The chin strap should be snug but not tight, with about one finger width clearance to avoid discomfort

Ensure the strap is positioned under the chin, not on the throat, for secure and comfortable fit

Due to different measurement methods, slight deviations may occur; actual product dimensions and fit should be prioritized.
