This work shows that multiple length‐scales must be considered concurrently to explain a polymer fiber's impressive mechanical performance and resilience. The considerations of interatomic interactions alone cannot explain the fracture strength observed in biological fibers. Instead, the fracture strength of a fiber depends strongly on the length‐scale of observation, including a fiber's sensitivity with respect to cracks and other flaws.
