Rockstar has not officially stated the GTA 6 map's size. The widely reported estimate is that the state of Leonida is roughly twice the size of GTA 5's map (or more), with far greater density and interior access.
What's confirmed vs estimated
- [Confirmed] Setting is the state of Leonida — Vice City plus surrounding regions (Everglades-like Grassrivers, the Leonida Keys, Port Gellhorn, Ambrosia, Mount Kalaga). Explore them on the interactive map.
- [Reported] ~2x+ GTA 5 land area, denser world, more enterable buildings — analyst/preview consensus, not a Rockstar figure.
- [Rumor] Specific square-mileage numbers circulating online are unverified.
The honest comparison
See our full GTA 6 vs GTA 5 breakdown and the map regions explained. The takeaway: bigger, but the real leap is detail per square mile — that's where Leonida separates from Los Santos.
