The PlayStation Store listing for GTA 6 has been reported to show a download of about 210 GB. Rockstar has not published an official install size, so treat this as a good estimate and not a promise.
Plan for more than 210 GB
Patches and updates usually add data after the first download. Aim to have at least 250 GB free before you start, so the install does not stop halfway.
How to free up space on PS5
- Open Settings > Storage and look at what is using the most space.
- Delete games you no longer play. You can download them again later.
- Remove old video clips and screenshots after you have copied them to a USB drive.
- Consider an M.2 SSD for the PS5 if your console is full all the time.
Can I play from a USB drive?
No. A USB drive can store PS5 games, but you must copy them back to the console storage (or a compatible internal M.2 SSD) to play.
