It isn’t officially confirmed yet, so the safest answer is that GTA 6’s exact size is still unknown. Online rumors vary a lot, with many guesses landing around 150–300 GB, while some newer posts claim much larger numbers like 676.7 GB, but those are unverified and conflict with other speculation.

What people are saying

  • Lower estimates: about 100–150 GB or 150–200 GB.
  • Mid-range estimates: about 200–300 GB.
  • Viral outlier claims: 676.7 GB, but these appear to be rumor-based and not reliably confirmed.

Practical takeaway

Plan for a large install, but don’t treat any exact number as final until Rockstar publishes the official storage requirement. A realistic expectation from the current chatter is roughly 200–300 GB, with the possibility of more on PC depending on textures and extra content.
