Engadget and MP1st reported on October 27 that the X account PlayStation Game Size claims GTA 6 is a 210GB download on PS5, with the same figure reportedly applying to PS5 Pro and Xbox Series X|S. Insider Gaming is said to have corroborated the number.
The figure is unconfirmed. Engadget notes it is unclear whether 210GB is the full install footprint or only the initial download, and day-one patches could change the total. Rockstar has not published an official file size, and the pre-order pages on the PlayStation Store and Xbox Store do not state one at the time of writing.
Why it matters: with launch on November 19 and the Standard Edition sold as a download-focused release in some markets, players on smaller SSDs may want to clear space now. Treat 210GB as a working estimate until Rockstar or a store listing confirms it. Nothing on pricing or editions changes.
