The font of copilot chat in Eclipse is too small. And the font setting of Eclipse do not take effect for copilot chat.

The font size issue in GitHub Copilot Chat within Eclipse is a known limitation. Here are several solutions you can try:

1. Adjust Eclipse UI Font Settings:

• Go to Eclipse > Preferences > General > Appearance > Colors and Fonts
• Look for "Text Font" or similar settings
• Increase the size to your preference
• This may help with the overall UI font size

2. Eclipse Plugin Settings:

• Check the GitHub Copilot extension settings in Eclipse
• Look for font size or UI scaling options specific to the Copilot panel
• Some versions have zoom controls in the chat panel itself (Ctrl+Mouse wheel)

3. Operating System DPI Settings:

• On Windows: Settings > Display > Scale and layout
• On macOS: System Preferences > Displays
• Increase DPI/scaling to make everything larger including Eclipse

4. Use VS Code Alternative:

• If Eclipse settings don't provide sufficient control, consider using GitHub Copilot Chat in VS Code
• VS Code has better font scaling options for extensions

5. File a Bug Report:

• If the issue persists, report it to the GitHub Copilot extension team
• Include your Eclipse version and OS for better debugging

This appears to be a UI rendering issue specific to the Eclipse integration, so adjusting display settings at multiple levels should help resolve it.

I have tried 1~3, it does not work. As to point 5, how to raise the bug to GitHub Copilot extension team?

Ctrl + + does not work for copilot chat in Eclipse, and the copilot version is GitHub Copilot 0.13.0

[suryaprakash0010]

Then in that case you can go to three dot option present in upper right side of your browser and adjust webpage size

It's not a webpage, the chat window is embedded in Eclipse.

Building on the previous suggestion, here are additional methods to adjust the Copilot Chat font size in Eclipse:

Primary Methods:

1. Browser-Style Zoom (Most Reliable)

   • Click inside the Copilot Chat window to focus it
   • Windows/Linux: Press Ctrl + Plus (+) to increase, Ctrl + Minus (-) to decrease
   • Mac: Press Cmd + Plus (+) to increase, Cmd + Minus (-) to decrease
   • Or hold Ctrl/Cmd and use mouse wheel to scroll zoom

2. Eclipse Preferences (Permanent Fix)

   • Go to: Window → Preferences (or Eclipse → Preferences on Mac)
   • Search for "Font" in the search box
   • Look for "Copilot Chat" or "General" → "Appearance" → "Colors and Fonts"
   • Find the chat/editor font setting and increase the size
   • Apply and restart if needed

3. WebView/Browser Settings

   • The chat window is rendered as a web view in Eclipse
   • Some font sizes are controlled by Eclipse's internal browser settings
   • Try: Preferences → General → Web Browsers → Check "Use external browser"

4. Check Eclipse Theme

   • Some themes (Light, Dark) have different default font sizes
   • Try switching themes to see if it helps
   • Window → Preferences → General → Appearance → Theme

5. Report as Bug (If nothing works)

   • If this is an accessibility issue, file a bug at:
   • GitHub Copilot for Eclipse repository issues
   • Include: Eclipse version, Copilot extension version, and accessibility needs

The browser zoom method is usually the quickest temporary fix, while adjusting preferences provides a permanent solution.

The Copilot Chat panel in Eclipse currently does not inherit the IDE’s font or text-rendering preferences. As a result, modifying editor or UI fonts via Preferences → General → Appearance → Colors and Fonts does not affect the font size used within the Copilot Chat view.

Available Workarounds

1. Enable Eclipse UI Scaling
   If your Eclipse version supports it, you may enable UI scaling through:
   Preferences → General → Appearance → Enable UI Scaling
   After enabling this option, restart Eclipse. This will scale most sidebar and webview-based panels, including Copilot Chat.

2. Adjust Operating System Display Scaling
   On macOS, changing the display scaling under
   System Settings → Displays → Scaled
   will affect all embedded webviews, which can indirectly increase the Copilot Chat font size.
