How big is the GTA 6 map?

Rockstar hasn't published a size. The most credible reports, from attendees of Rockstar's July 2026 preview collated by Vice, put the map at about twice GTA V's and roughly three times Red Dead Redemption 2's playable area, with Vice City alone said to be twice the size of Los Santos. Rockstar has named six regions: Vice City, Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia and Mount Kalaga.
