Selecting the right helmet size for your atv racing helmet

Take a tape measure and wrap it around your head evenly at the point just above your head, so that it wraps from where you start around the back, across your forehead in a complete circle. Remember, it doesn't matter how tall your head is, its about how wide it is around.

FITTING YOUR HELMET

The helmet should fit so that the visor line is above the eyebrows. The fit should be snug and there should be no additional gap. A properly fitted helmet will minimize the internal bounce factor in the event of an impact, so this is important.

The chin strap will be adjustable and should fit snugly. If the strap is too loose the helmet won't be able to do its job and will shift or break loose on impact. It is also important that the strap is snug and comfortable and not cranked too tight as this can affect your airway and possibly choke you if you wipe out. If its not comfortable then its probably too tight, if there is a gap under it, then its probably too loose. The chin strap should easily adjust, and should fit under your chin and not in contact with your throat.

ENGLISH MEASUREMENTS

Alright now, wrap that tape measure around your head above your ears at the level of your eyebrows.  Congratulate  yourself on having a perfect shaped head and consult this section if your browser has difficulties processing tables

Inches

21.5 to 22.5

You will need a small helmet

22.5 to 23 1/4
This is the size range for medium helmets

23 1/4 to just under 24 inches

Your head will require a large helmet

24 inches to 24 and 3/4 inches

This requires an extra large helmet (xl)

If you are a sturdy person with a large head, it makes particular sense to protect that obviously massive brain.  If you are  measuring anything larger than XL you will want a double extra large helmet (XXL) for keeping it all together.

METRIC MEASUREMENTS

For measuring your helmet using the metric system use this section

Small - 54 to 56 cm

YOUTH SIZES

Youth sizes for helmets are for any heads that are smaller than the small size. There are variants in youth sizes and the youth helmet selection has an assortment of these. You will have to check the product detail page to make sure that any helmet that is selected for a youth size fits appropriately.

You should use this chart if you aren't sure what your helmet size is.  Just grab a tape measure and do it.  If you are estimating the size for someone elses head, try and remember how big their head is compared to yours and adjust accordingly.  

As with all apparel products, sizes may vary somewhat by manufacturer
