For systems with zero entropy and/or zero Lyapunov exponents we introduce and study the notions of scaled entropy and scaled  Lyapunov exponents which are used to characterize the sub-exponential separation of nearby trajectories. We briefly discuss their properties and relations between scaled entropy and scaled  Lyapunov exponents, and provide examples.
