The comparison is to Manhattan Island

Grand Theft Auto V’s playable world is commonly described as larger in area than Manhattan, the densely built-up island at the heart of New York City. The comparison is about the map’s overall footprint—not a claim that every part of the game world is packed with streets and buildings at Manhattan’s density.

Why the game world feels so expansive

Los Santos, the game’s fictional city, is only one part of the map. Roads lead out into suburbs, open countryside, desert, and mountainous terrain, while the coastline and surrounding water make the setting feel larger still. Players can cross these very different environments without leaving the game world, so the map’s scale comes through as a journey rather than a number.

That variety also serves the game’s design: a city chase, a drive through the hills, and an escape across open country can all happen on the same connected map. Manhattan is a useful real-world benchmark for the land area, but the memorable difference is how much the game changes around you as you travel across it.
