The GTA 6 map is twice the size of GTA 5
The claim
Leonida is around two to two and a half times the size of the GTA 5 map.
Rumor Circulating widely but not officially confirmed. Treat with caution.
Widely repeated, not officially confirmed. You will see “2x”, “2.1x”, even “2.5x the size of GTA 5” stated as fact. It is not. These are community estimates from trailer analysis and mapping projects, not a figure Rockstar has published.
What Rockstar actually said
Rockstar has described the world as its largest to date. It has not released a full playable map, and it has not given a square mileage or a direct size multiple against GTA 5. Any exact number you read is an estimate.
Why the estimates vary
Fans measure using coastline shots, driving times in trailers, and the known real world analog of Florida. Those methods produce a range, which is why the numbers disagree, landing anywhere from around two to nearly three times GTA 5. A range of guesses is not a confirmation.
Our rating
Rumor, and a reasonable one. The map is clearly large, likely the biggest Rockstar has built, but the specific multiplier is unproven. For the confirmed regions, see the map overview and the locations database.
