  Infinite-range interactions are known to facilitate the production of highly
entangled states with applications in quantum information and metrology.
However, many experimental systems have interactions that decay with distance,
and the achievable benefits in this context are much less clear. Combining
recent exact solutions with a controlled expansion in the system size, we
analyze quench dynamics in Ising models with power-law ($1/r^{\alpha}$)
interactions in $D$ dimensions, thereby expanding the understanding of spin
squeezing into a broad and experimentally relevant context. In spatially
homogeneous systems, we show that for small $\alpha$ the scaling of squeezing
with system size is identical to the infinite-range ($\alpha=0$) case. This
indifference to the interaction range persists up to a critical value
$\alpha=2D/3$, above which squeezing degrades continuously. Boundary-induced
inhomogeneities present in most experimental systems modify this picture, but
it nevertheless remains qualitatively correct for finite-sized systems.
