Rockstar has named six regions in the state of Leonida — Vice City, the Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia, and Mount Kalaga National Park — directly on its official GTA VI page. That's it. Rockstar has never published a square-kilometer figure for this or any past GTA game.
Every number in this article past that point — including every one you've seen elsewhere — is a fan estimate built from trailer footage, camera angles, and coordinate guesswork. Some of that work is genuinely careful. None of it is official.
Type "GTA 6 map size" into a search bar and you'll get answers ranging from 100 to 210 square kilometers, with confidence levels that don't match the uncertainty involved. So let's separate what Rockstar has said from what the community has calculated, and be honest about which is which — the same split we ran into sorting fact from fan theory on the GTA VI cast.
In this piece
What Rockstar has actually confirmed
Start with the solid ground. Rockstar's own GTA VI page names six regions that make up Leonida, its fictional take on Florida: Vice City, the sprawling Leonida Keys, the Everglades-inspired Grassrivers wetlands, the faded coastal town of Port Gellhorn, the industrial community of Ambrosia, and Mount Kalaga National Park to the north.
That's a genuinely useful confirmation — it tells you the shape of the world Rockstar is building, from swampland to mountains to island chains. What it doesn't tell you is how big any of it is in square kilometers. No developer in the GTA series has ever released that number before launch, and Rockstar hasn't broken that pattern here. It's worth remembering, too, that Leonida's real-world counterpart is close enough to inspire actual marketing decisions — Miami Beach recently approved real beach branding tied to the game, which says something about how closely fiction and geography line up here.
The size estimates, and why they don't agree
In the absence of an official figure, fan cartographers have spent two years triangulating one. The most-cited approach comes from the GTAForums Coordinate Mapping Project, which uses distances between recognizable landmarks in trailer footage and screenshots — bridges, airports, road markings — to reconstruct a scale model of Leonida.
The results cluster in a wide band: most serious estimates land between 100 and 160 square kilometers, roughly 2.1 to 2.7 times the size of GTA V. A few outlier calculations claim figures as high as 210 square kilometers, but those generally include a rumored northern panhandle that hasn't been confirmed as drivable terrain, and mainstream mapping projects treat that figure skeptically.
| Title | Community estimate | Vs. GTA V | Basis |
|---|---|---|---|
| GTA VI: Leonida | ~100–160 km² (some outliers to ~210 km²) | ~2.1x–2.7x | Fan coordinate mapping; unconfirmed |
| GTA V: San Andreas | ~76–81 km² | Baseline | Widely cited community measurement |
| GTA IV: Liberty City | ~16.1 km² | 0.2x | Widely cited community measurement |
| San Andreas (2004) | ~32–38 km² | 0.4–0.5x | Community measurement; sources vary |
| Vice City (2002) | ~9.1 km² | 0.1x | Widely cited community measurement |
None of these figures, GTA VI included, come from Rockstar. Community estimates via Sportskeeda and VICE.
Why such a wide spread even among people using similar methods? Two reasons come up constantly: whether an estimate counts open water and coastline as part of the "map," and whether it includes the disputed northern panhandle. Change either assumption and the number moves by tens of square kilometers.
Every past GTA map, by community measurement
Context helps here, because Rockstar's map sizes have never grown in a straight line. Vice City in 2002 measured a modest 9.1 square kilometers by most community counts. Liberty City in GTA IV, despite arriving four years later on more powerful hardware, actually measured smaller than 2004's San Andreas at roughly 16 square kilometers, because Rockstar prioritized density over sprawl. GTA V then jumped to around 76–81 square kilometers, folding Los Santos and Blaine County's mountains and desert into a single landmass.
If the higher end of the current GTA VI estimates holds up, Leonida would represent the single biggest jump in the series' history — bigger, proportionally, than the leap from Vice City to San Andreas.
Why San Andreas felt bigger than it measures
Here's a detail that should make everyone more cautious about square-kilometer bragging rights: 2004's San Andreas measures smaller than GTA V by most counts, yet an entire generation of players remembers it as the bigger game.
That's friction at work. San Andreas capped vehicle speeds low, wound its roads through mountains with few straightaways, and locked story progress behind three separate cities you had to unlock in sequence. GTA V removed almost all of that friction — sports cars hit triple digits in seconds, freeways ran straight, and a fighter jet could cross the entire map in under two minutes. A smaller world with more resistance can feel larger than a bigger one with none.
That's the real question hanging over Leonida's water-heavy, mountain-light geography: without San Andreas's vertical barriers to block sightlines and slow travel, Rockstar will need swamps, waterways, and traffic density to do the same job.
Size isn't the whole story
Raw square footage is an incomplete measure of how big a game feels, which is exactly why GTA IV's comparatively small Liberty City is still remembered as one of the densest, most alive cities Rockstar has built. Interior access, verticality, and how many of those square kilometers actually have something in them matter as much as the total.
On that front, Rockstar has said more than it has about map size: its own materials and the August 2026 Extended Look point toward a significant increase in enterable interiors compared to GTA V, across homes, stores, and Vice City high-rises. Specific interior counts you may see cited — claims of 500 or 700-plus enterable buildings — haven't been confirmed by Rockstar and should be read as fan projection, not fact.
FAQ
How big is the GTA 6 map compared to GTA 5?
No official figure exists. The most-cited community estimates put Leonida at roughly 2.1 to 2.7 times the size of GTA V's San Andreas, with total footprint estimates ranging from about 100 to 160 square kilometers depending on methodology.
Has Rockstar confirmed the GTA 6 map size?
No. Rockstar has never published an official square-kilometer figure for any GTA game before launch, GTA VI included. It has confirmed six named regions — Vice City, Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia, and Mount Kalaga National Park — without giving their combined size.
Is the GTA 6 map bigger than Red Dead Redemption 2?
Most community estimates say yes, since RDR2's map is generally measured at around 75 square kilometers, below even the low end of current GTA VI projections. As with GTA VI's own size, this comparison rests on unofficial community measurements for both games.
Why do map-size estimates vary so much between websites?
Mainly two reasons: whether an estimate counts water and coastline as part of the total area, and whether it includes a rumored, unconfirmed northern panhandle. Adjusting either assumption shifts the total by tens of square kilometers, which is why you'll see figures anywhere from about 100 to 210 square kilometers.
Why did San Andreas feel bigger than GTA V despite being a smaller map?
Friction. Low vehicle speeds, winding mountain roads, and three sequentially unlocked cities made 2004's San Andreas feel like a long journey despite measuring smaller than GTA V. GTA V removed most of that friction, which is part of why raw square kilometers alone don't predict how big a game feels.
