How big is the biggest galaxy in the Universe?

If by big we mean physical dimension, the largest known galaxy is most likely IC1101. IC1101 is gargantuan even among galaxies; it’s a super elliptical galaxy with a diffuse stellar halo that to extends to at least 1.4 million light years. The Milky Way’s halo by comparison
