Ever wondered why your computer slows down when running heavy applications or games? One reason could be an insufficient page file size. In Windows 11, the page file (also called a paging file or virtual memory) acts as an extension of your physical RAM. By adjusting its size, you can optimize your system’s performance.
In this step-by-step guide, we’ll show you how to change the page file size in Windows 11, why it matters, and the best settings for your PC.
What Is a Page File in Windows 11?
Think of your RAM as your desk space and your page file as a drawer. When your desk gets too cluttered, Windows uses that drawer to store extra stuff temporarily.
Key Facts:
-
It’s stored on your system drive (usually C:).
-
It’s used when your RAM is full.
-
It helps prevent system crashes and “low memory” errors.
Why Change the Page File Size?
Windows automatically manages the page file size by default. However, manual adjustments may be needed when:
1. Running Heavy Applications
Games, video editors, or 3D rendering software may require more virtual memory.
2. System Performance Issues
If you frequently see “Your system is low on virtual memory” messages, increasing the page file helps.
3. Limited Disk Space
Reducing the page file size can free up storage space (but be careful).
What Is the Recommended Page File Size for Windows 11?
Microsoft recommends:
-
Initial Size: 1.5 times your installed RAM
-
Maximum Size: Up to 3 times your installed RAM
Example: If you have 8 GB of RAM,
-
Initial size = 12,288 MB
-
Maximum size = 24,576 MB

Should You Increase or Decrease Page File Size?
Increase If:
-
You run memory-intensive apps.
-
Your system often shows low memory warnings.
Decrease If:
-
You need more disk space.
-
You have large amounts of physical RAM (e.g., 32 GB or more).
Does Changing Page File Size Improve Performance?
Yes—if done correctly! A properly set page file:
-
Reduces system crashes
-
Improves multitasking
-
Speeds up load times for heavy apps
However, setting it too low may cause errors, while making it too high can waste disk space.
Common Problems and Solutions
1. Page File Keeps Resetting
-
Ensure you have administrative rights.
2. System Crashes After Changing Page File
-
Boot into Safe Mode and restore default settings.
3. Not Enough Disk Space
-
Move the page file to another drive if possible.
Is It Safe to Disable Page File in Windows 11?
No! Disabling it entirely can cause apps to crash when RAM runs out. Even with 16–32 GB RAM, keeping a small page file is recommended.
Can You Move Page File to Another Drive?
Yes! If you have multiple drives:
-
Uncheck Automatically manage paging file size.
-
Disable it on C:.
-
Set a custom size on another drive (preferably an SSD for faster performance).
Best Practices for Page File Settings
-
Keep it on an SSD for better speed.
-
Avoid setting both minimum and maximum sizes too low.
-
Monitor performance after changes.
Final Thoughts
Changing the page file size in Windows 11 is a powerful way to fine-tune your system’s performance. Whether you’re a gamer, video editor, or just want smoother multitasking, adjusting your virtual memory can make a noticeable difference.
Just remember: don’t set it too low, and always restart after making changes.
