Sizing for an Helmet
Measuring for a water sport 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. Use it to find which size of helmet suits you:
Wrap the measuring tape around the fullest part of the head - this will be just above the ears and about a half-inch above the eyebrows for most - and take the measurement at the forehead. To get the most accurate measure, have a friend help with this step.
Take the measurement and compare to the size chart on the page for the desired helmet (you might have to scroll down). Each manufacturer has sizing which is specific to its own models, so only rely on the size chart produced for the helmet brand being considered.
A well-fitting helmet contributes to a safer and more comfortable ride. If the helmet does not fit right, it can cause
pain which often leads to dangerous distractions, and it may not completely protect the rider's head in a crash. Therefore, finding an helmet which fits the rider correctly is very important to the helmet's twin missions of comfort and safety. Spend enough time finding the right helmet and you will find that the helmet almost disappears while wearing and yet it is right where it needs to be should the ride go wrong. Be smart. Be safe. Ride with a correctly sized motorcycle helmet and enjoy the ride for years to come.
