We use resonant and non-resonant X-ray diffraction measurements incombination with first-principles electronic structure calculations and MonteCarlo simulations to study the relationship between crystal structure andmultiferroic orders in the orthorhombic perovskite manganites, o-$R$MnO$_3$($R$ is a rare-earth cation or Y). In particular, we focus on how the internallattice parameters (Mn-O bond lengths and Mn-O-Mn bond angles) evolve underchemical pressure and epitaxial strain, and the effect of these structuralvariations on the microscopic exchange interactions and long-range magneticorder. We show that chemical pressure and epitaxial strain are accommodateddifferently by the crystal lattice of o-$R$MnO$_3$, which is key forunderstanding the difference in magnetic properties between bulk samples andstrained films. Finally, we discuss the effects of these differences in themagnetism on the electric polarization in o-$R$MnO$_3$.
