How big can the sidewinder get?

The sidewinder, a species of rattlesnake found primarily in the deserts of the southwestern United States and northwestern Mexico, typically grows to an average length of 2 to 3 feet (0.6 to 0.9 meters). However, some individuals can reach lengths of up to 4 feet (1.2 meters). Their slender bodies and unique adaptations allow them to move efficiently across sandy terrain.
