Sagittarius A* ia spread about 26 million kilometers or 16 million miles in diameter. It is large compared to the black holes left behind when massive stars die.

Size of blackhole is measured by it's "event horizon" means a distance from the center of the black hole within which nothing can escape.

This is the real image of Sagittarius A*. It's impossible to take direct image of blackhole because light can't escape it's gravity.
