TLDR
In this article, a critical grain size for twinning has been found using transmission electron microscopy and the experimentally observed minimum grain size is consistent with values derived from a balance of the cubic to tetragonal elastic strain and twin surface energies.About:

Size effects in PbTiO3 nanocrystals: Effect of particle size on spontaneous polarization and strains
TL;DR: The spontaneous polarization and spontaneous strain in mechanically unclamped and surface charge compensated PbTiO3 nanocrystals were determined as a function of particle size in the range <150nm by differential scanning calorimetry and x-ray powder diffraction, respectively as mentioned in this paper.
