Driver SF was pretty big, LA Noir as well at 8 sq miles (4 times Los Santos in GTA V)


As comparison here's Los Santos (city)


LA Noir was huge.

That map of Los Santos is from GTA: SA, not GTA V. GTA V's Los Santos is WAY bigger, though I'm not sure its biger than LA in LA Noire.

What about LC in GTA IV or Rome in AC: B?
