FortNine Size Chart
Use this FortNine Size Chart as a starting point for comparing rider gear measurements before choosing a size. Because helmets, gloves, boots, jackets, pants, and protective gear can vary by brand and product style, always check the size guide and fit notes on the specific product page before ordering.
Motorcycle Helmet Size Chart
Measure around the widest part of your head, just above your eyebrows and ears. Keep the tape level and comfortably snug, then compare your measurement with the helmet chart below.
| Helmet Size | Head Circumference (in) | Head Circumference (cm) | Hat Size |
|---|---|---|---|
| XS | 20 7/8 - 21 1/4 | 53 - 54 | 6 5/8 - 6 3/4 |
| S | 21 5/8 - 22 | 55 - 56 | 6 7/8 - 7 |
| M | 22 1/2 - 22 7/8 | 57 - 58 | 7 1/8 - 7 1/4 |
| L | 23 1/4 - 23 5/8 | 59 - 60 | 7 3/8 - 7 1/2 |
| XL | 24 - 24 3/8 | 61 - 62 | 7 5/8 - 7 3/4 |
General Glove Size Chart
For gloves, measure across your hand from the knuckle of your forefinger to the knuckle of your pinky finger. Use your dominant hand and keep your hand relaxed while measuring.

| XL | 11 | 4 1/8 - 4 5/8 |
| 2XL | 12 | 4 5/8 - 5 1/8 |
Boot Size Chart
Boot sizing may vary by brand and model. Measure your foot length from heel to longest toe, then compare it with the chart shown for the product you are considering.
| Euro Size | US Size | Foot Length (cm) | Foot Length (in) |
|---|---|---|---|
| 39 | 5.5 | 24.5 | 9.6 |
| 39.5 | 5.5 | 24.7 | 9.7 |
| 40 | 6 | 24.9 | 9.8 |
| 41 | 7 | 25.7 | 10.1 |

How to Choose Your Size
- Start with the chart that matches the exact product type you are buying.
- Compare your body or foot measurement to the chart, not only the letter size you usually wear.
- Review the product page for brand-specific fit notes, size availability, and any model-specific sizing guidance.
- For protective riding gear, the fit should feel secure without limiting movement or circulation.
Measuring Tips
- Use a flexible measuring tape whenever possible.
- Measure over the base layer or riding layer you plan to wear with the item.
- Keep the tape snug, level, and flat against the body without pulling it too tight.
- For helmets and gloves, measure more than once and use the largest consistent measurement.
- For boots, measure both feet and use the larger foot as your guide.
Fit Notes & Between-Sizes Advice
If your measurement falls between two sizes, consider the product type before choosing. Helmets should feel snug and secure, while gloves should allow controlled finger movement without extra bunching. Boots should leave enough room for riding socks without heel lift or pressure points.
When you are between sizes, review the product-detail page first. Some gear is designed with a slim, regular, relaxed, or race-style fit, and those fit notes can be more helpful than a general size chart alone.
