      Hi OMGMaster2005,

      Great question! I’m not sure there is an actual limit of how big a black hole can get. For example, the black holes I look at can be as large as 100 billion of our own Sun, or even larger! For black holes this big though, they are located at the centre of galaxies, so I guess the maximum size would depend on how big the galaxy itself can get!
