Mass-size relation of early-type galaxies. Massive early-type galaxies (shown in gray circles, Janz et al. 2016), compact early-type galaxies (shown in gray plus symbols, Ferré-Mateu et al. 2021), and dwarf early-type galaxies in the Virgo cluster (shown in tan colored symbols, Lisker et al. 2006) are compared with the sample of isolated and quenched dwarfs (shown as symbols color-coded in a similar way to Fig. 1). Virgo dwarfs hosting NSC located in the cluster’s outskirts, as discussed in Fig. 1, are marked in dark red. The stellar masses are taken from the corresponding cited references. The vertical gray line marks the log(M_⋆/M_⊙) = 9.5.
