GTA 5 launched in 2013 with a map that defined a generation of open-world expectations. Thirteen years later, GTA 6 is the first Rockstar map built specifically to surpass it. This piece is a direct comparison - not a launch hype piece, but a structural look at where the two maps differ and what those differences mean in actual play.

If you want the full GTA 6 picture in isolation, see our GTA 6 map guide and GTA 6 map size analysis. This page is the comparison piece.

Raw size: how much bigger is Leonida?

GTA 5's playable area is roughly 49 sq miles - Los Santos plus Blaine County, plus a meaningful underwater zone. Leonida hasn't been measured officially, but trailer footage and the geography Rockstar is referencing put estimates between 1.5x and 2x that figure. Our GTA 6 map size deep-dive tracks the latest evidence.

Raw acreage is the wrong headline number though. The bigger story is what's inside the map - which is where GTA 6 pulls dramatically ahead.

Density: where the gap is biggest

GTA 5 had around 140 enterable interiors. Trailer footage and developer comments suggest GTA 6 lands in the high hundreds, possibly four-figure when you count smaller buildings. That's not a 1.5x increase - that's a generational jump in density.

Vice City specifically is built denser than Los Santos by a wide margin. Our GTA 6 Vice City map guide breaks down what trailer footage shows: more side streets, more interiors per block, more vertical variation.

Terrain variety: a real new biome

GTA 5 had three primary terrain types - urban Los Santos, rural Blaine County, and the desert/mountain north. Leonida has those three plus a genuinely new one: the Everglades-style wetlands in central Leonida and the Florida Keys-inspired island chain to the south.

Wetlands are the headline. Rockstar has never built a true swamp environment before, and the gameplay systems it unlocks (airboat traversal, alligator encounters, dense-foliage stealth) don't have an equivalent in any prior GTA.

Underwater and aerial space

GTA 5 had a decent underwater zone with some sunken-ship content. GTA 6's underwater volume is larger by virtue of the longer coastline and the Keys archipelago. Aerial space is also more meaningful - the geographic distance between regions makes aircraft genuinely useful in a way they weren't in GTA 5, where most points of interest were within easy driving distance.

Expect this to reshape vehicle balance: helicopters and small planes should matter more in GTA 6 than they did in GTA 5.

What stays the same

Don't read this as 'GTA 5 was small.' Both maps share the same Rockstar design DNA: hand-built density, satirical world-building, dual urban/rural balance, and hidden detail rewarding exploration. GTA 6 is an evolution of GTA 5's approach, not a departure from it. The protagonist switching mechanic carries over (now Lucia and Jason instead of Michael, Franklin, Trevor), and most of the open-world systems players expect are present.

If you're returning from GTA 5, expect everything to feel familiar - just bigger, denser, and with more terrain variety. For frame-by-frame trailer evidence, see our trailer location breakdown.

Implications for modding

The GTA 5 modding scene has had over a decade to mature. The GTA 6 modding scene starts from scratch when PC ships - but it's starting from a much higher technical baseline (modders bringing skills built on GTA 5 transfer directly). Custom map content - tracked at GTA 6 map downloads when ready - will likely catch up faster than GTA 5's scene did.
