Rockstar has not published an official map area for GTA 6, and no square-kilometer figure appears in any store listing or Newswire post. Community estimates, based on the 26-minute Extended Look footage and presumed scale of Leonida state, put the map well above GTA 5’s roughly 80 square kilometer footprint, but those numbers remain speculation until Rockstar confirms them.
What is officially known: the game releases November 19, 2026 on PS5 and Xbox Series X|S, digital only, with no PC version announced. The 150 GB install size you may have seen is a community guess, not store data. The Extended Look trailer shows Vice City, surrounding wetlands, a Keys-style island chain, and rural roads, suggesting a mix of dense urban zones and open countryside, but exact dimensions are absent.
For scale reference, GTA 5’s map could be crossed in about 15 minutes of driving. GTA 6 is expected to be meaningfully larger, but “expected” is the operative word. Treat any specific area or file size claim as unverified until Rockstar or the store pages say otherwise.
