Game Storage Space Calculator
Calculate how much storage you need for your game library.
See how many games fit on common SSD and HDD sizes.
Game Storage Space requirements have grown dramatically over the years. Modern AAA games routinely exceed 100 GB, making storage planning essential for any PC or console gamer.
How this calculator works: The total storage needed is calculated as:
Total = (Number of Games × Average Size per Category) + OS Reserve
The OS reserve accounts for your operating system, system files, temporary files, and essential applications. Windows typically needs 40-60 GB, while keeping at least 10-15% of your drive free is recommended for optimal performance.
Average game sizes by category:
- Indie games (~5 GB): Smaller titles like Celeste, Hollow Knight, or Hades. These are lightweight and storage-friendly.
- AA games (~25 GB): Mid-tier games like Helldivers 2, Valheim, or Subnautica. Good production quality without massive file sizes.
- AAA games (~75 GB): Major releases like Elden Ring, Cyberpunk 2077 (base), or Baldur’s Gate 3. High-quality assets drive the large size.
- AAA with DLC (~120 GB): Games like Call of Duty: Modern Warfare (with Warzone), Final Fantasy XV, or Microsoft Flight Simulator. DLC, updates, and high-res texture packs push these to enormous sizes.
SSD vs HDD: Solid State Drives (SSDs) are significantly faster than Hard Disk Drives (HDDs). Game load times on an SSD can be 2-5 times faster. Many modern games are designed with SSDs in mind, and some titles on PS5 and Xbox Series X require SSD storage. For PC gaming, an NVMe SSD is the gold standard, while a SATA SSD is still a major improvement over an HDD.
However, HDDs remain cost-effective for storing games you do not play frequently. A common setup is a smaller SSD (500 GB to 1 TB) for active games and a larger HDD (2-4 TB) for your archive.
Common drive sizes:
- 256 GB SSD: Enough for the OS plus 2-3 AAA games
- 512 GB SSD: OS plus 5-6 AAA games
- 1 TB SSD: OS plus 10-12 AAA games or a large indie library
- 2 TB SSD: Comfortable for most gamers with mixed libraries
- 4 TB HDD: Great for archiving a large collection
Tips for managing storage:
- Uninstall games you have finished or are not actively playing.
- Use Steam’s Storage Manager to see which games use the most space.
- Disable HD texture packs for games where you do not notice the difference.
- Keep at least 10-15% of your SSD free to maintain performance and drive longevity.
- Consider game streaming services for titles you only play occasionally.
