Warm Dark Matter is a CDM modification for which particle velocities are not negligible. Such modifications are introduced in order to solve some of the CDM issues on subgalactic scales. We discuss the constraints that warm dark matter particles have to satisfy in order to share the experimental success of CDM on cosmological scales. We apply these constraints to the realistic scenarios with sterile neutrino and light gravitino as dark matter particles.
