Windows Page File Size Calculator
Here's a comprehensive table summarizing all you need to know about Windows Page File Size:
| Aspect | Details |
|---|---|
| Default Behavior | Windows automatically manages the page file size12 |
| Recommended Size | 1.5 to 4 times the physical RAM1 |
| Minimum Size | 1.5 times the physical RAM1 |
| Maximum Size | 4 times the physical RAM1 |
| System-Managed Limits | Minimum: Varies based on usage history and RAM (RAM ÷ 8, max 32 GB) Maximum: 3 × RAM or 4 GB, whichever is larger5 |
| Location | Typically on the system drive (C:)2 |
| Manual Configuration | Accessible via Advanced System Settings > Performance > Advanced > Virtual Memory24 |
| When to Adjust | If experiencing lag, BSOD errors, or for specific performance needs1 |
| Custom Size Recommendation | Initial and maximum size set to 50% of system RAM6 |
| Disabling | Possible, but not recommended unless certain of sufficient RAM6 |
| Impact on Performance | Can improve performance, especially on systems with slower disks6 |
| Relation to Physical Memory | Extends committed memory beyond physical RAM limits3 |
| System Commit Limit | Sum of physical memory and all page files combined3 |
| File Name | pagefile.sys |
Additional Considerations
- SSD/NVMe Drives: With faster drives, a larger static page file size may be beneficial6.
- Memory Dumps: Adequate page file size is crucial for generating complete memory dumps for diagnostics4.
- Multiple Drives: Page files can be distributed across multiple drives for improved performance2.
- 64-bit Systems: May require larger page files due to increased memory addressing capabilities5.
Remember that while manual configuration is possible, it's often best to let Windows manage the page file automatically unless you have specific performance requirements or are experiencing issues related to virtual memory.
