For every integer n ≥ 2 and every origin-symmetric convex body $K\subset\mathbb R^n$, we prove that the Gromov width of $\mathop{\mathrm{int}}\nolimits K\times\mathop{\mathrm{int}}\nolimits K^\circ$ is 4. We construct smooth symplectic embeddings of standard balls of every capacity $0\lt c\lt 4$ into this polar product. Volume preservation then resolves the symmetric Mahler conjecture positively in every dimension.
