GTA 6 Map Size: How Big Is Leonida Really?
On this page
Current status
- Current status: No official size; six regions confirmed; fan estimates converge around ~2× GTA 5.
- Last verified: July 2, 2026.
- Official sources checked: Rockstar GTA VI site (region names), trailers and screenshots.
- What is confirmed: the named regions and the world's visible variety.
- What is not confirmed yet: any measurement — every number below the confirmed row is estimation.
What's actually confirmed: Leonida's six regions
Rockstar's own site names the playable state's regions — the one hard scale fact:
| Region | Real-world flavor |
|---|---|
| Vice City | Miami — the neon heart |
| Leonida Keys | Florida Keys island chain |
| Grassrivers | Everglades swampland |
| Port Gellhorn | Gulf-coast port town |
| Ambrosia | Sugar-industry inland |
| Mount Kalaga | Highland/forest country |
Six distinct biomes — city, keys, swamp, coast, farmland, mountains — confirmed by name. GTA 5, for comparison, offered one city and one county. Whatever the square-mileage, the confirmed regional variety already exceeds any prior GTA — the map and setting guide tours each region in depth.
The size estimates, tiered by credibility
| Claim | Source | Verdict |
|---|---|---|
| GTA 5's map ≈ 75 km² (49 land) | Established measurement | Confirmed baseline |
| RDR2 ≈ comparable to GTA 5 overall | Established measurement | Confirmed baseline |
| GTA 6 ≈ 1.5–2× GTA 5 | Community mapping projects triangulating trailer/screenshot landmarks | Reported/Analysis — the credible band |
| GTA 6 ≈ 180–250 km²+ | Extrapolations of the above | Analysis — wide error bars |
| "Twice RDR2" / "biggest map in gaming" claims | Viral posts | Unverified — exceeds any evidence |
| Specific leaked dimensions | 2022 leak-era maps | Rumor — dated builds, never authoritative |
The mapping-project methodology — matching filmed landmarks to plotted coordinates — has a decent track record from the RDR2 era, which is why the ~2× band is taken seriously. But no estimate survives contact with an official map, which Rockstar hasn't shown.
The better question: density, not diameter
Rockstar's own history argues size is the wrong metric (Analysis):
- GTA 5's map felt smaller than its 75 km² — much was mountain and desert buffer.
- RDR2's similar footprint felt enormous — density and detail did the work.
- GTA 6's signals all point density-first: the rumored hundreds of enterable buildings, simulation depth in every trailer frame, and a budget that bought detail, not just acreage.
- And online expansion room: a live-service decade benefits more from unbuilt density headroom than raw edges — GTA Online famously never grew its map.
A ~2× GTA 5 world at RDR2-class density would be, functionally, the biggest world Rockstar has ever shipped — regardless of where the exact number lands. The GTA 5 comparison runs the head-to-head.
Confirmed vs rumored: map size claims
| Claim | Status |
|---|---|
| Official GTA 6 map size published | False — no figure exists |
| Six named regions across Leonida | Confirmed — Rockstar site |
| Roughly 2× GTA 5 | Reported/Analysis — mapping-project estimate |
| Biggest Rockstar map ever | Analysis — likely if estimates hold |
| Specific km² figures circulating | Unverified — false precision |
| 2022-leak map layouts as authoritative | Rumor — dated builds |
The bottom line
Confirmed: six regions of unprecedented variety. Estimated: about twice GTA 5. Official: nothing — yet. When Rockstar publishes the real map, this page converts estimates to measurements the same day. Until then, the map guide covers what the world contains rather than how many kilometers contain it.

Frequently asked questions
- How big is the GTA 6 map?
- Officially unpublished. Community mapping projects estimate roughly twice GTA 5's ~75 km² — which would make Leonida Rockstar's largest world ever.
- What regions are confirmed in GTA 6?
- Six, named by Rockstar: Vice City, Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia, and Mount Kalaga.
- Is GTA 6's map bigger than GTA 5's?
- Almost certainly — the confirmed regional variety alone exceeds GTA 5, and every credible estimate lands at 1.5–2× its size.
- Is GTA 6's map bigger than RDR2's?
- Estimates say yes, but no official comparison exists — RDR2 and GTA 5 occupy similar footprints, and GTA 6's estimates exceed both.
- When will Rockstar show the official map?
- Unannounced — full maps historically arrive at launch or in final marketing. Fan cartography rules until then.
