The spectral diameter of a symplectic ball is shown to be equal to its
capacity; this result upgrades the known bound by a factor of two and yields a
simple formula for the spectral diameter of a symplectic ellipsoid. We also
study the relationship between the spectral diameter and packings by two balls.
