We use GALFIT to fit single S\\'ersic models to the rest-frame optical profile of our galaxies, which is a mass-selected sample complete to our redshift and mass limit. Our primary result is that at fixed rest-frame wavelength and stellar mass, galaxies get progressively smaller, evolving as $\\sim (1+z)^{-0.71\\pm0.19}$ up to $z \\sim 8$.
