  We study various aspects of capacity of entanglement in the squeezed states
of a scalar field theory. This quantity is a quantum informational counterpart
of heat capacity and characterizes the width of the eigenvalue spectrum of the
reduced density matrix. In particular, we carefully examine the dependence of
capacity of entanglement and its universal terms on the squeezing parameter in
the specific regimes of the parameter space. Remarkably, we find that the
capacity of entanglement obeys a volume law in the large squeezing limit. We
discuss how these results are consistent with the behavior of other
entanglement measures including entanglement and Renyi entropies. We also
comment on the existence of consistent holographic duals for a family of
Gaussian states with generic squeezing parameter based on the ratio of
entanglement entropy and the capacity of entanglement.
