Calculate the contracted length of an object moving at relativistic speeds. Length contraction means objects appear shorter along the direction of motion when observed from a stationary frame.

Length measured in the object's rest frame
Velocity as a fraction of the speed of light
How this calculator works
Contracted length equals the proper length divided by the Lorentz factor. Moving objects are shorter along the direction of motion.
