There is a direct relationship between the mass of a black hole and the size of its event horizon. if you know the one, you know the other. So if a black hole is the highest mass ever seen, it would also be the largest in terms of its event horizon.

That said, inside the event horizon we simply can't know what goes on. So the "actual size" (meaning, how much space the matter inside the black hole occupies) is, I believe, simply unknown.
