How big is GTA 6? Storage needed and how to expand your PS5 or Xbox

Between 120 and 200 GB based on Rockstar's precedents. Your PS5 has less free space than you think: how much you need and which SSD works.

"How big will GTA 6 be?" is one of the most-searched questions about the game, and it's not idle curiosity: the answer determines whether you can install it on day one or spend the night uninstalling games. Here are the numbers and the solution.

How much space GTA VI will take: the estimate

Rockstar hasn't published an official size. But the company's precedents are very consistent and allow a reliable estimate:

• Red Dead Redemption 2 (2018): ~150 GB
• GTA V in its current-gen version with updates: over 100 GB
• GTA Online separately added tens of GB more

GTA VI has a map estimated at twice GTA V's, current-gen textures and, according to leaks, accessible interiors across the city. The reasonable estimate lands between 120 and 200 GB, and you should expect online mode and later patches to grow it.

The problem: your console has less space than you think

Here's the trap that catches many people out:

• Standard PS5: 825 GB nominal → ~667 GB actually usable
• PS5 Slim / Pro: 1 TB / 2 TB nominal → ~842 GB / ~1.7 TB usable
• Xbox Series X: 1 TB nominal → ~802 GB usable
• Xbox Series S: 512 GB nominal → ~364 GB usable (the tightest case)

The operating system takes a share. If you have Call of Duty installed (around 200 GB), a couple of sports games and an open world or two, you very likely won't fit GTA VI without uninstalling.

The PS5 solution: an M.2 SSD (and the requirements it must meet)

The PS5 has an internal expansion slot. Not any SSD will do; Sony's requirements are strict:

• M.2 NVMe PCIe Gen4 x4 format
• Sequential read speed of 5,500 MB/s or higher
• Heatsink mandatory — without one the console rejects it or it overheats

Options that meet the requirements:

• WD_BLACK SN850P 2TB — €329 · Our pick. Officially licensed for PlayStation: heatsink pre-fitted and guaranteed compatibility. Plug and play.
• Lexar EQ790 2TB with heatsink — €269.99 · Saves around €60 while meeting spec. A good option if a lesser-known brand doesn't bother you.

Installation takes about five minutes: remove the side panel, unscrew the slot cover, insert the SSD and format it from the console menu. It doesn't void the warranty.

The Xbox Series X|S solution: expansion card

Xbox works differently and there's less flexibility: it only accepts proprietary expansion cards that plug into the back. They cost more per gigabyte than an M.2 SSD, but installation is literally inserting it.

Cheaper alternative: you can connect an external USB drive to store current-gen games, but not to run them — you'll have to move them to internal storage to play. It works as an archive, not as a solution for GTA VI.

What if I don't want to spend?

A perfectly valid option: uninstall. Go through your library and delete what you don't play — save data and digital games stay on your account and you can reinstall whenever you want. Freeing up 150 GB solves the problem without spending a cent.

Our advice: do it before November 19, not on the day. Downloading a 150 GB game with servers hammered during a global launch can take hours.

How big is GTA 6?

Rockstar hasn't published the official figure. Based on Red Dead Redemption 2 (~150 GB) and GTA V (over 100 GB), the reasonable estimate is between 120 and 200 GB, growing later with online mode and patches.

Which SSD works with PS5?

It must be M.2 NVMe PCIe Gen4 x4, with read speeds of 5,500 MB/s or higher and a mandatory heatsink. Officially licensed PlayStation models meet every requirement out of the box.

Can I play GTA 6 from an external hard drive?

On both Xbox and PS5, current-gen games can be stored on an external drive but must run from internal storage or a compatible expansion. A USB drive works for archiving, not for playing.

Will GTA 6 fit on an Xbox Series S?

It's the tightest case: the Series S has around 364 GB usable. With a game of 120-200 GB, you'll likely need to uninstall other titles or use an expansion card.
