Far-infrared dust continuum effective radius (filled circles) and rest-frame UV/optical effective radius (filled stars) as a function of the stellar mass of our galaxies, colour-coded by redshift. All our galaxies have systematically higher R_eff, FIR than R_{eff, UV/opt}. As a result, R_eff, FIR of our galaxies strongly deviate from the R_eff, FIR–M_stars relations of Gómez-Guijarro et al. (2022) at z < 2.5 and z > 2.5, shown by the solid and dashed black lines, respectively, as they are more extended. On the other hand, their R_{eff, UV/opt} agree with the R_eff, UV–M_stars relation (blue shaded area) derived for LTG at z ∼ 2.5 by van der Wel et al. (2014). The green shaded area corresponds to the R_eff, UV–M_stars relation of z ∼ 2.5 early-type galaxies (ETG; van der Wel et al. 2014).
