Helmet Sizing Chart
Helmets must fit properly for optimum performance. Don't guess your size. To ensure a proper fit, take a tailor's measuring tape and measure around your head above the ears and just above your eyebrows.
If your head size is :
| Head size (inches) | 20 | 20½ | 21 | 21½ | 22 | 22½ | 23 | 23½ | 24 | 24½ | 25 |
| Head size (cm) | 51 | 52 | 53.5 | 54/55 | 56 | 57 | 58.5 | 60 | 61 | 62 | 63.5 |
| Hat size | 6½ | 6⅝ | 6¾ | 6⅞ | 7 | 7⅛ | 7¼ | 7⅜ | 7½ | 7⅝ | 7¾ |
Helmets must be securely and snugly fastened before engaging in any activity.
To find the most comfortable fit for your helmet, follow Troxel's fitting guide.
