What is actually published: no size, and a pre-load date of November 12
Checked on 3 September 2026: no official Grand Theft Auto VI store listing publishes a download size. Not PlayStation Store, not Xbox Store. What is published is the pre-load date. Rockstar Games and Take-Two stated in their 24 June 2026 announcement that digital pre-orders can begin pre-loading on 12 November 2026, seven days before the 19 November 2026 launch. The same announcement puts the physical version, which carries a download code in the box, on shelves from 12 November for exactly that reason: so the pre-load can start on the same day.
Those seven days are the only firm number you can plan around right now. Every specific gigabyte figure circulating today is an estimate or a datamine rather than store data, which is why none appears on this page.
PlayStation Store: seven days of pre-load, no file size
The PlayStation Store Standard Edition page lists four things in the edition contents: the game, the Vintage Vice City Pack, one month of GTA+, and a line reading "7-Day Pre-load". Seven days is precisely the 12–19 November window, so the store and the publisher announcement agree; they just say it differently.
What the page does not carry is a download size. PlayStation does not print package size on the web product page at all. That figure appears in the store on the console itself and in the download queue, and only once the package is genuinely downloadable. Everything else on the page is checkable: platform PS5, a "PS5 Pro Enhanced" badge, one player, offline play enabled, Remote Play supported, and a release timestamp of 11/19/2026 05:00 AM UTC.
Xbox Store: no size row, and what the 329 MiB record really is
The Xbox Store page for product 9NL3WWNZLZZN gives publisher, developer, a release date of 11/19/2026, an "Optimized for Xbox Series X|S" badge, 13 supported languages, and single-player capability. It shows no size row, and it does not mention the pre-load date; that comes from Rockstar's announcement, not from Microsoft's listing.
One detail deserves to be stated plainly, because it is easy to misread. The store record loaded behind that page currently reports an install size of 344,731,648 bytes, roughly 329 MiB, and the same value appears in the US, Hungarian and Polish markets. It is not shown in the visible part of the page, and it is not the size of the finished game: it is the placeholder for a pre-order package. No final install size has been published by Rockstar, Microsoft or Sony.
Do the free work first: audit space, do not buy hardware
Without a size figure, preparing for launch is a housekeeping job rather than a purchase, and it costs nothing.
On the console, Settings > Storage shows how much free space you have and what each game occupies. That list usually surfaces titles you have not launched in months. On PS5, Game Library > Move Games and Apps shifts them to USB extended storage; on Xbox, the equivalent is moving or copying them to an external drive. The worst outcome is that you re-download something later.
If that still does not free enough room, expansion is the next step. It is worth waiting until the store publishes the real size, though, because until then you do not know what capacity you actually need.
PS5: what Sony requires of an M.2 SSD
PlayStation's support page states the requirements exactly. These are the physical and electrical limits of the expansion bay, not suggestions:
- Interface: PCI-Express Gen4x4 supported M.2 NVMe SSD (Key M), Socket 3 (Key M). M.2 SATA SSDs are not supported.
- Capacity: 250 GB to 8 TB.
- Form factor: 2230, 2242, 2260, 2280, 22110.
- Size including the cooling structure: width up to 25 mm, length 30/42/60/80/110 mm, thickness up to 11.25 mm, of which up to 8.0 mm above the board and up to 2.45 mm below it.
- Sequential read speed: 5,500MB/s or faster is recommended.
- Cooling: a heat-dissipation mechanism such as a heatsink or heat transfer sheet is required.
The same page states two limits that product round-ups tend to drop. Sony does not guarantee that every drive meeting the published specification will work, and a drive faster than 5,500MB/s will not necessarily match the performance of the console's internal SSD. If a game misbehaves on M.2 storage, the official advice is to move it back to internal storage. The M.2 SSD also has to be formatted in its entirety on first use, so anything already on it is erased.
PS5 and USB drives: fine for storage, not for playing
USB extended storage on PS5 requires a SuperSpeed USB 5 Gbps or later connection and a drive between 250 GB and 8 TB. It cannot be connected through a hub, and only one extended storage drive can be in use at a time. The decisive limit is different, though: PS5 games cannot be played directly from USB extended storage. You have to copy the game data back to console storage first. PS4 games are exempt and run from the USB drive.
For Grand Theft Auto VI, then, an external USB drive is an archive: it parks old titles so the internal SSD has room. That is the cheapest route, and for many players it will be enough on its own.
Xbox: the expansion card and a USB drive are not interchangeable
Xbox's own storage primer separates the two in a table. An external USB 3.1 HDD or SSD stores any Xbox game and plays Xbox One, Xbox 360 and original Xbox titles directly, but it does not play games optimized for Xbox Series X|S and does not replicate the speed of the internal SSD. The Storage Expansion Card, which slots into the Storage Expansion port on the back of the console, does both: it was designed against the Xbox Velocity Architecture API to reproduce the internal SSD's performance exactly, and the same card works in Series X and Series S. The internal SSD delivers 2.4 GB/s of raw I/O throughput.
Grand Theft Auto VI carries the "Optimized for Xbox Series X|S" badge in the Xbox Store. Read together, those two official facts mean you will not be able to launch the game from an external USB drive; you will only be able to store it there. That is our reading of the two listings, not a separate statement from Microsoft.
Microsoft introduced the card at 1 TB. Current capacities and prices sit on your own Xbox Store accessories pages and change over time, which is why no price appears here.
Four things nobody has published
Worth knowing before anyone quotes you a confident number:
- Download size per platform. Not published, for PS5, Xbox Series X or Series S.
- A separate Series S size. Not published. Xbox wrote in 2020 that Series S games can be up to 30% smaller on average because they do not need the highest 4K texture set, but that is a general design note, not a Grand Theft Auto VI figure.
- Free space required to install. Not published.
- The exact hour the pre-load opens. The announcement gives the day, 12 November, and no time.
How to check the number the day it appears
The only source that will give you an exact figure is the product page in your own regional store: on PS5, the Grand Theft Auto VI page inside the console's PlayStation Store; on Xbox, the install-size line on the Microsoft Store product page. From 12 November that becomes verifiable in practice, because the package will genuinely be downloadable.
Until then, two pages take this further. The platform list covers which machines the game is actually coming to, and the PC status and system requirements page explains why no official PC figure exists yet.
