This paper derives the Dimensional Structural Inertia Law within the Information-Dynamic Theory (IDT). Using the structural inertia framework and relaxation geometry, we show that the effective structural inertia depends on spatial dimension as m*(d) = C r*² / (2A(4 − d)). The result suggests that stable structural regimes naturally select three spatial dimensions due to the divergence of inertia near d → 4. This provides a geometric explanation for dimensional stability in physical reality.
