Galaxy size as a function of M_★ for the LEGA-C galaxies at 0.6 ≤ z_spec ≤ 1. Based on their sSFR, galaxies are separated into star-forming (blue stars) and quiescent (red points) populations. Post-starburst galaxies are indicated as yellow squares. For each galaxy population, we fitted a linear relation between the median sizes in each 0.1 dex mass bin and the stellar mass (gray symbols). To avoid the flattening of the relations at the low-mass end, we fit star-forming galaxies with log(M_★/M_⊙) ≥ 9.8 and quiescent galaxies with log(M_★/M_⊙) ≥ 10.3.
