Changing Text Size in Windows: A Complete Guide

Introduction / Why This Is Needed

By default, Windows selects a UI scale optimal for your monitor. However, this size may be inconvenient: text can seem too small on a large screen or, conversely, giant on a small laptop. Incorrect scaling also causes blurriness in text and interface elements in older programs.

This guide shows how to fully control the size of text and elements in Windows 10 and 11. You will be able to:

• Increase or decrease the overall UI scale.
• Adjust the font size for specific elements only (menus, window titles, messages).
• Solve the problem of blurry text in individual applications.
• Use both modern settings and classic Control Panel methods.

Requirements / Preparation

Before you begin, ensure:

1. You have administrator rights on the computer (required for some compatibility settings and registry edits).
2. You are working under an account with standard settings (not a shared or restricted account).
3. Applying changes to the system scale will require signing out and signing back in or rebooting.
4. It is recommended to create a system restore point, especially if you plan to change settings via the registry.

Step-by-Step Instructions

Step 1: Change the Overall UI Scale (Primary Method)

This is the simplest and most effective way to change the size of ALL elements: icons, text, window borders.

1. Open Windows Settings. Press Win + I or click Start → gear icon.
2. Go to System → Display.
3. In the Scale & layout section, find the Scale slider.
4. Select the desired percentage from the list (e.g., 100%, 125%, 150%). Windows will suggest optimal values for your screen resolution.
5. Important: After selecting a new scale, the system will display a notification: "You must sign out and sign back in to apply these changes". Click Sign out now. After signing back in, all windows, text, and UI elements will become larger or smaller.

💡 Tip: If the desired percentage is not in the list, click the link Try a different scale (may not be available in all versions). Be careful: very high values (e.g., 200%+) can lead to incorrect display in some programs.

Step 2: Configure Text Size Only (Without Changing Scale)

If you want to keep the size of buttons and icons the same but increase only the readable text (in menus, titles, taskbar), use this method.

1. In the same System → Display section, scroll down the page.
2. Find and click the link Advanced scaling settings.
3. In the window that opens, under Scale & layout, find the Text size setting.
4. Use the slider to select the desired font size (e.g., 100%, 110%, 125%).
5. Click Apply. The system will prompt you to sign out and sign back in to apply the changes to all system elements.

⚠️ Important: This setting only affects Windows system elements and applications that use system fonts. Font size in browsers (Chrome, Edge) and many third-party programs is controlled within those programs themselves (e.g., Ctrl + mouse wheel or font settings in their preferences).

Step 3: Classic Method via Control Panel (For Individual Elements)

This is an older but sometimes useful method, especially in Windows 10, which gives maximum control over specific text categories.

1. Open Control Panel. Press Win + R, type control, and press Enter.
2. Go to Hardware and Sound → Display.
3. In the left pane, find and click Change only the text size.
4. In the new window, from the dropdown list Select the item you want to change the size of, choose a category:
   • Window titles
   • Menus
   • Message boxes
   • Tooltips
   • Palette titles
   • Icons
5. Below, select the desired font size (e.g., 9, 10, 11, 12 pt) and, if necessary, the font (usually leave as Segoe UI).
6. Click Apply. The system will prompt you to restart your computer for full application of changes.

⚠️ Note: In Windows 11, this method may be limited or not work for all categories. Methods 1 and 2 are preferable.

Step 4: Fixing Blurry Text in Individual Applications (DPI Scaling)

Sometimes after increasing the system scale, older or simple programs (e.g., older Java apps, utilities) display blurry.

1. Locate the executable file (.exe) for that program (e.g., on the Desktop or in C:\Program Files\...).
2. Right-click on it → Properties.
3. Go to the Compatibility tab.
4. Click the button Change high DPI settings.
5. In the window that opens, check the box Override high DPI scaling behavior.
6. Select one of the options from the dropdown menu:
   • Application — the program manages scaling itself. Try this if the interface "jumps" or elements are positioned incorrectly.
   • System (Enhanced) — Windows attempts to scale the program. Often provides a clear image but may "cut off" UI elements.
   • System — classic scaling, which almost always results in blurriness. Use only if other options don't work.
7. Click OK → Apply → OK in the file properties.
8. Restart the program itself (not the entire system).

Step 5: Advanced Configuration via Registry (Expert Method)

Caution! Incorrect registry changes can make the system unstable. Create a restore point.

For fine-tuning the system font size (e.g., for elements that don't change via Settings):

1. Press Win + R, type regedit, and press Enter.
2. Navigate to: HKEY_CURRENT_USER\Control Panel\Desktop
3. Find the string value parameter LogPixels.
   • If it doesn't exist, create it: Right-click → New → String Value → name LogPixels.
4. Set the value according to the desired scale (in hexadecimal format, HEX):
   • 96 (decimal) = 100% (default)
   • 120 = 125%
   • 144 = 150%
   • 168 = 175%
   • 192 = 200%
   • Full list: 96, 120, 144, 168, 192, 216, 240.
5. Sign out and sign back in or reboot the PC.
6. To apply changes to some system elements, you may also need to modify the parameters Win8DpiScaling (set to 1) and DPIscalingVer (set to 0x00001000 for Windows 8.1/10) in the same registry branch. After changing these, a reboot is also required.

Verifying the Result

1. After signing back in or rebooting, open several typical windows:
   • Windows Explorer.
   • Start menu.
   • Taskbar (icons and text).
   • Window properties (title, buttons).
2. Ensure the text is readable without eye strain and UI elements do not overlap each other.
3. Launch the problematic application from Step 4 and check if the blurriness is gone.
4. If something went wrong, revert the settings back (100% scale) or use your system restore point.

Potential Issues

• After changing the scale, the interface "jumps" or windows are misplaced. This often happens with outdated programs. Use the method from Step 4 for the specific .exe file. Try the Application or System (Enhanced) options.
• Text in the browser (Chrome, Firefox) or in VS Code does not change with the system scale. This is normal. Font size in these programs is managed within them. Use Ctrl + mouse wheel or font settings in the browser/IDE's Settings.
• Nothing changed after configuring via registry (LogPixels). Ensure you signed out and signed back in. Check if this setting conflicts with the DPIscalingVer parameter. For most users, methods 1-3 are sufficient.
• After increasing the scale, the interface became blurry (not sharp). This may be related to the graphics driver or monitor settings. Try:
  1. Update your graphics driver from the manufacturer's website (NVIDIA, AMD, Intel).
  2. In your graphics driver control panel (NVIDIA Control Panel / AMD Software), find DPI or scaling settings and try toggling them.
  3. Verify that your monitor is using its native (recommended) resolution.
• Cannot select the desired scale percentage in Windows Settings. This may mean your graphics or monitor driver is not providing Windows with information about supported modes. Update your display drivers. As a last resort, you can use the registry method (LogPixels).
