Distribution of effective radii for galaxies in the morphological sample. In grey (filled) we show the total size, in red (hatched) the bulge size, and in blue (hatched) the disk size. Disks are mostly found between roughly 1 kpc and 6 kpc, with very few galaxies with disk sizes beyond 10 kpc. The lack of disks below 1 kpc is due to the size selection criterion from Sect. 6.1. On the other hand, the majority of bulges are found below 2 kpc. The total size of galaxies is mainly driven by the disk component.
