Calculate your ideal gravel bike frame size using inseam measurements, riding style, and terrain preference. Gravel-specific geometry requires different sizing than road or mountain bikes.
Gravel bike sizing borrows from road bike methodology but incorporates key differences for off-road capability. While road bikes prioritize aerodynamics and efficiency, gravel bikes balance comfort, control, and versatility across mixed terrain.
The base calculation uses your inseam multiplied by 0.67, similar to road bikes. However, adjustments for riding style (racing vs. bikepacking) and terrain roughness can shift your ideal size by 1–2 cm. Gravel bikes also require more standover clearance than road bikes for safe dismounts on uneven ground.
| Frame Size | Rider Height | Inseam Range | Size Label |
|---|---|---|---|
| 48 cm | 5'0" – 5'3" (152–160 cm) | 27–29" (69–74 cm) | XS |
| 50 cm | 5'3" – 5'5" (160–165 cm) | 29–30" (74–76 cm) | S |
| 52 cm | 5'5" – 5'7" (165–170 cm) | 30–31" (76–79 cm) | S/M |
| 54 cm | 5'7" – 5'10" (170–178 cm) | 31–33" (79–84 cm) | M |
| 56 cm | 5'10" – 6'0" (178–183 cm) | 33–34" (84–86 cm) | M/L |
| 58 cm | 6'0" – 6'2" (183–188 cm) | 34–36" (86–91 cm) | L |
| 60 cm | 6'2" – 6'4" (188–193 cm) | 36–37" (91–94 cm) | XL |
| 62 cm | 6'4"+ (193+ cm) | 37"+ (94+ cm) | XXL |
Aggressive geometry optimized for speed on gravel roads.
Balanced setup for varied terrain and riding styles.
Comfort-focused geometry for loaded, multi-day rides.
Gravel bike fit differs from road bike fit in several important ways. A slightly more upright position reduces fatigue on long rides over rough terrain. Wider handlebars with flare improve control on descents and provide more leverage on loose surfaces.
Consider your tire choice when fine-tuning fit — wider tires raise the bottom bracket slightly and change the effective standover height. If you plan to run both 700c and 650b wheels, ensure your frame size works well with both setups.
