Bern, SixSixOne, Bell, & Giro Helmet Sizing

Achieve the Perfect Fit in just a few Easy Steps

To get the right fit for any of our helmets you'll need just one quick measurement. If you don't have a cloth measuring tape, you can use our Printable Measuring Tape or simply use a length of string and compare it to a ruler or regular tape measure.

Once you have your measurements, refer to the "Size Chart" on the helmet you're interested in and compare your figures to the values on the size chart to find your best fit.


With tape level, measure the widest point of your head,
approximately one inch (2.5 cm) above your eyebrows.
