How to Change Font Size on Computer Screen in Windows 11: A Guide

By / September 11, 2025

Ever feel like the text on your Windows 11 computer screen is too tiny to read comfortably—or maybe too large, taking up too much space? Don’t worry, you’re not alone. The good news is, Windows 11 lets you easily change the font size across the entire system without needing third-party tools.

In this guide, I’ll walk you through different methods to adjust text size on your Windows 11 PC, whether you want a slight boost for readability or a complete scale-up for accessibility.

Why Change the Font Size in Windows 11?

Changing the font size isn’t just about looks—it’s about comfort and usability.

  • Better readability: Ideal for people with vision difficulties.

  • Less eye strain: Larger fonts reduce squinting during long work sessions.

  • Improved accessibility: Makes navigation easier for seniors or visually impaired users.

  • Customization: Tailor your PC to match your workflow.

Method 1: Change Font Size via Settings

The easiest and most common way to change text size is through the Settings app.

Steps

  1. Press Windows + I to open Settings.

  2. Go to Accessibility in the left sidebar.

  3. Select Text size.

  4. Drag the slider under Text size preview to increase or decrease font size.

  5. Click Apply to save changes.

✅ Your screen text will now appear larger or smaller system-wide.

Method 2: Change Font Size Using Display Scale

Scaling changes not just text but also icons, menus, and apps—perfect if everything feels too small.

Steps

  1. Open Settings (Windows + I).

  2. Go to System > Display.

  3. Under Scale & layout, find Scale.

  4. Choose a percentage (e.g., 100%, 125%, 150%).

👉 Example: At 125%, text, apps, and icons will all appear larger.

Method 3: Change Font Size for Specific Apps

Not all apps obey system-wide settings. Some let you adjust font size individually.

  • Web browsers (Edge/Chrome/Firefox): Use Ctrl + Plus (+) or Ctrl + Minus (-) to zoom in/out.

  • Microsoft Word/Excel: Adjust font size directly in the toolbar.

  • Mail & Calendar app: Go to settings inside the app and tweak text size.

This way, you don’t have to scale the entire system if you only struggle with specific apps.

Method 4: Use Magnifier for Temporary Font Enlargement

If you don’t want permanent changes, Windows 11’s Magnifier tool is your friend.

Steps

  1. Press Windows + Plus (+) to open Magnifier.

  2. Use Windows + Plus (+) to zoom in further, or Windows + Minus (-) to zoom out.

  3. Close Magnifier with Windows + Esc.

✅ This is great for occasional use when you need to zoom in quickly.

Method 5: Registry Hack (Advanced Users Only)

If you want full control over system fonts (not just size), you can tweak Windows Registry. ⚠️ Be careful—mistakes can cause issues.

Steps

  1. Press Windows + R, type regedit, and hit Enter.

  2. Navigate to:

    HKEY_CURRENT_USER\Control Panel\Desktop

  3. Find and modify values like LogPixels for scaling.

  4. Restart your PC to apply changes.

👉 Only recommended if you know what you’re doing.

How to Reset Font Size Back to Default

If things look weird after changing font size, you can easily reset.

  1. Open Settings > Accessibility > Text size.

  2. Drag the slider back to 100%.

  3. Or go to System > Display > Scale and select 100% (Recommended).

This restores the original Windows 11 look.

Tips for Better Readability on Windows 11

  • Enable ClearType: Improves text sharpness. Search “Adjust ClearType text” in Start menu.

  • Increase screen resolution: Higher resolution = sharper text.

  • Use Dark Mode: Reduces glare and makes text easier on the eyes.

  • Try different scaling: Some laptops look best at 125% or 150%.

Common Problems and Fixes

Problem 1: Text looks blurry after scaling

  • Fix: Log out and log back in. If still blurry, try a recommended resolution.

Problem 2: Some apps don’t follow font size changes

  • Fix: Adjust text size inside the app itself or use Compatibility Settings.

Problem 3: Fonts look too large and break layout

  • Fix: Reset scaling to 100% or experiment with smaller increments.

Final Thoughts

Changing the font size in Windows 11 is a simple tweak that can drastically improve your comfort and productivity. Whether you go with a subtle increase for readability, full system scaling, or just zoom in apps, Windows gives you plenty of flexibility.

So, if text on your screen feels too small or too overwhelming, now you know exactly how to fix it.
