IC 1101 is a class S0 supergiant ... A 2017 paper suggests that IC 1101 has the largest core size of any galaxy with a core radius of around 4.2 ± 0.1 ...

Listed below are galaxies with diameters greater than 700,000 light-years. This list uses the mean cosmological parameters of the Lambda-CDM model based on results from the 2015 Planck collaboration, where H 0 = 67.74 km/s/Mpc, Ω Λ = 0.6911, and Ω m = 0.3089. [3]
A2029 is a Bautz–Morgan classification type I cluster due to its large central galaxy, IC 1101. Abell 2029 has a diameter of 5.8–8 million light-years. This type of galaxy is called a cD-type brightest cluster galaxy and may have grown to its large size by accreting nearby galaxies. Despite its relaxed state, it is the central member of a ...
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
Sure add half-light radius = effective radius for all ellipticals and/or IC 1101, but it is misleading at best, and of little practical value. Considering astronomers efforts over just on 100 years of deep study, they still have yet to come up with a universal method of deciding a galaxy's size.

IC 1011 is a barred spiral galaxy [1] with apparent magnitude of 14.7, [3] and with a redshift of z=0.02564 (SIMBAD) [1] or 0.025703 (NASA), [3] yielding a distance of 100 to 120 megaparsecs. [3] Its light has taken 349.5 million years to travel to Earth.
