[FEATURE] Terminal font family setting in desktop app

Problem Statement

The Code tab in Claude Desktop uses a fixed font with no way to change it. If you use Oh My Zsh with a theme that needs Nerd Font glyphs (Powerlevel10k, Starship, etc.), the terminal shows broken squares instead of the actual icons.

The font is installed and works in every other terminal on the system. The desktop app just doesn't pick it up.

Related issues cover font size (#48237) and dyslexic-friendly fonts (#40469), but none ask for font family selection.

Proposed Solution

A "Terminal font family" text field in Settings > Appearance. Just needs to accept a CSS font-family string so xterm.js uses the right font. No picker needed.

I'd also agree here, but purely on the basis that the font is illegible for me. If we compare MacOS native terminal against the one in Claude Code, one you start adding errors, symbols etc, its too difficult to read

Yes. Especially in light themes, the font rendering in the Claude Code Desktop terminal looks terrible.
Harsh and hard to read.

Upvoting this request 👍

Upvoting this request as well! This would be great so I can use neovim in the Terminal panel within the claude code app

The font is terrible. It looks like a typewriter with a worn-out ribbon,

+1 on this request.

My setup:

• macOS, Claude.app desktop (v2.1.158)
• Powerlevel10k with MesloLGS NF Regular 12pt
• Font is installed at ~/Library/Fonts/MesloLGS NF Regular.ttf and works perfectly in macOS Terminal.app (the default terminal)

Confirmed behavior: The font IS installed system-wide but Claude.app's integrated terminal ignores it and falls back to a default monospace font, rendering Powerlevel10k icons as broken squares.

Workaround I'm using: Launching claude . from macOS Terminal.app instead of using the built-in terminal tab — works perfectly there.

The proposed fix (a font-family field in Settings > Appearance) would be ideal. Even just reading from a config key in ~/.claude/settings.json like "terminalFontFamily": "MesloLGS NF" would solve this for power users.

I cannot use Windows Claude Desktop because of the fonts, they look terrible (see attached first image).
Would love to have the option to use the Courier New font (see second image from Claude via browser) and also an option to set the font size. Maybe even via CSS.

Thanks!

Please allow us to customize the fonts in claude desktop terminal

Please add customization for terminal font, it is currently unusable in certain scenarios.
