The size-luminosity relation for local dwarf ellipticals, LSBGs, and UDGs from various studies is shown, with r_eff,g (in parsecs) on the y-axis and M_g (mag) in the g-band on the x-axis. Red crosses and magenta circles represent the LSBGs and UDGs from this work. Brown triangles, purple diamonds, and lime green squares indicate UDGs from the MATLAS survey (Marleau et al. 2021), the Virgo cluster (Lim et al. 2020), and the Coma cluster (Bautista et al. 2023). The blue circle marks the Fornax dwarf from Eigenthaler et al. (2018), orange stars represent local dwarf ellipticals from Paudel et al. (2023), and black pentagons show low-mass Virgo cluster members from Ferrarese et al. (2020). The grey lines represent constant surface brightness values, ranging from ${\overline{\mu }}_{𝑔}=20$ to ${\overline{\mu }}_{𝑔}=30$ mag arcsec⁻², with each subsequent line increasing by 2 magnitudes.
