Borderlands 4 has a surprisingly small file size compared to its predecessor. The download size is approximately:
- PlayStation 5: 28.168 GB
- Xbox Series X/S: 29.5 GB
- PC: Around 65 GB (though some sources note up to 100 GB available space is recommended)
This is notably smaller than Borderlands 3, which was about 53 GB on PS5 at launch and grew with updates and DLCs to over 100 GB on PC. The relatively small size for Borderlands 4 is likely due to texture optimizations and improvements from using Unreal Engine 5. However, day-one patches might increase this size slightly.
Regarding the in-game world size, the map of Borderlands 4 is estimated to be around 33 square miles, which indicates a substantial but manageable open- world area for players to explore.
In summary, Borderlands 4 is about 28-30 GB on consoles and larger on PC due to higher graphical requirements, with an open world map roughly 33 square miles in size.
