  We derive von-K\'arm\'an plate theory from three dimensional, purely
atomistic models with classical particle interaction. This derivation is
established as a $\Gamma$-limit when considering the limit where the
interatomic distance $\varepsilon$ as well as the thickness of the plate $h$
tend to zero. In particular, our analysis includes the ultrathin case where
$\varepsilon \sim h$, leading to a new von-K\'arm\'an plate theory for finitely
many layers.
