Knowing your helmet size is important when shopping for a new helmet, as a good fit can help to protect your head in the case of an accident. Here are some tips to help you determine your helmet size:
Measure the circumference of your head: Start by using a tape measure to measure the circumference of your head, as this will provide you with the most accurate fit. Measure around your head, just above your eyebrows and ears.
Find the right size: Once you have the measurement, you can use the sizing charts provided by most helmet manufacturers. This will tell you which size of helmet to choose. Most helmet size charts start from a small size, usually around 21 inches, and go all the way up to 25 inches.
Adjust the straps: Once you have the correct size helmet, adjust the straps so it fits snugly. The straps should fit comfortably around your ears and a few inches below your chin.
Test the fit: Finally, try the helmet on and shake your head vigorously. If the helmet moves back and forth too much, then it is too big and you should go for a smaller size.
