Rockstar has not announced the install size for Grand Theft Auto VI. The PlayStation Store and Xbox Store listings for the game do not show a file size, and Rockstar’s official materials have not mentioned one. Any number you see online, including the commonly cited 150 GB, is a community estimate or a rumor, not a confirmed fact.
Expected download size
If you want a rough benchmark, Grand Theft Auto V on modern consoles requires around 100 GB. GTA 6 is built on a newer engine with a larger map, so a bigger install is likely, but that is speculation. The final size will depend on compression, day-one patches, and whether the game ships with additional language packs or high-resolution textures.
The game releases on November 19, 2026, as a digital-only title on PlayStation 5 and Xbox Series X|S. Since there is no physical disc, you will need enough free storage at launch. Sony and Microsoft usually list download sizes a few weeks before release, so check storefronts in late October or early November for the official number. Until then, treat any specific gigabyte figure as unconfirmed.
