[FEATURE] Terminal font family setting in desktop app

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.

Update for anyone still subscribed: the setting asked for here has shipped, but it doesn't reach the terminal.

Settings → Code appearance → Code font says it sets the font "for code and terminal." It applies to code blocks and diffs only — the terminal hardcodes fontFamily: '"SF Mono", ui-monospace, Menlo, Consolas, monospace' at its call site and never reads the configured value, so Nerd Font glyphs still render as tofu.

I traced it to the exact call site and filed it with a suggested one-line fix in #82205.
