Measuring for motorcycle helmet size is as simple as looking for a good fitted hat. The difference is in how the helmet fits over the rider's head. The best tool for this is a seamstress or tailor's tape measure. It is flexible enough to wrap around the rider's skull and marked in useful increments for determining an accurate size.

Start by wrapping a flexible measuring tape horizontally around your head, approximately 1 inch above your eyebrows, write down the measurement, refer to the brand's size chart, and select the best corresponding size. If you are in between sizes, try the smaller size first, as suggested in the MC Garage video.

Measure the circumference of the rider’s head just above the eyebrows and ears using a cloth tape measure. Compare the measurement to the size chart provided by the helmet manufacturer to find out the appropriate size. You can try on different styles and brands of helmets to find the best fit. Shake your head to check for proper fit.

You can follow these three simple steps to have the expected outcome: Determine your head shape. Measure with a flexible tape. Note the dimension and check the motorcycle helmet size chart.
