We give a formula for the superdimension of a finite-dimensional simple [Formula: see text]-module using the Su–Zhang character formula. This formula coincides with the superdimension formulas proven by Weissauer and Heidersdorf–Weissauer. As a corollary, we obtain a simple algebraic proof of a conjecture of Kac–Wakimoto for [Formula: see text], namely, a simple module has nonzero superdimension if and only if it has maximal degree of atypicality. This conjecture was proven originally by Serganova using the Duflo–Serganova associated variety.
