We present the coupled nonlinear integral equations (NLIE) governing the finite size effects in N = 1 super sine-Gordon model for the vacuum as well as for the excited states. Their infrared limit correctly yields the scattering data of the super sine-Gordon S-matrix conjectured by Ahn [C. Ahn, Nucl. Phys. B 354 (1991) 57-84]. Ultraviolet analysis is in agreement with the expected conformal data of c = 3 / 2 CFT. Conformal perturbation theory further corroborates this result.
