Customizing Your Editor with Better Coding Fonts

If you’re squinting at your screen after hours of coding or struggling to distinguish between 0 and O in your JavaScript, you’re using the wrong font. The right coding font transforms your development experience—reducing eye strain, improving code readability, and yes, even making those long debugging sessions more bearable.

This guide walks you through choosing and configuring modern programming fonts for your editor and terminal, with practical setup instructions for VS Code and JetBrains IDEs.

Why Default Fonts Fall Short

Most editors ship with system defaults like Courier New or Consolas. While functional, these fonts weren’t designed for modern development workflows. The best programming fonts offer:

• Clear character distinction: No more confusing 1, l, and I
• Proper hinting: Sharp rendering at typical coding sizes (12-14px)
• Unicode coverage: Support for modern JavaScript, emojis, and international characters
• Optional ligatures: Transform => and !== into single, readable glyphs

Top Modern Coding Fonts for 2025

Fira Code: The Ligature Pioneer

Fira Code remains the gold standard for ligature support. Its 150+ programming ligatures work seamlessly with JavaScript and TypeScript:

const isValid = input !== null && input.length >= 3;
const transform = (data) => data.map(item => item * 2);

Available in both standard and Nerd Font variants (FiraCode NF), it’s perfect for developers who want icons in their terminals.

JetBrains Mono: The Balanced Choice

JetBrains Mono strikes an excellent balance between readability and aesthetics. Its increased x-height and optimized character shapes reduce eye fatigue during long coding sessions. The font includes both ligature and non-ligature variants.

Cascadia Code: Microsoft’s Modern Take

Cascadia Code ships as the default in Windows Terminal. It offers multiple variants:

• Cascadia Code: Standard with ligatures
• Cascadia Mono: No ligatures
• Cascadia Code NF: Nerd Font variant with modern icon support

Monaspace: GitHub’s Innovation

Monaspace represents the latest evolution in variable monospace fonts. Its five variants (Neon, Argon, Xenon, Radon, Krypton) each serve different purposes, with the standout feature being “texture healing”—subtle width adjustments that improve readability without breaking monospace alignment.

Monaspace also ships “Frozen Fonts,” preconfigured variants designed for editors that don’t expose OpenType feature controls, ensuring ligatures and stylistic sets work consistently across tools.

Monaspace vs Fira Code: While Fira Code excels at ligatures, Monaspace’s texture healing creates more natural reading flow. Choose Monaspace for longer coding sessions; stick with Fira Code if you prioritize extensive ligature support.

Configuring Fonts in Your IDE

VS Code Setup

VS Code separates editor and terminal fonts, allowing independent customization:

{
  // Editor font settings
  "editor.fontFamily": "'JetBrains Mono', 'Fira Code', monospace",
  "editor.fontSize": 14,
  "editor.fontLigatures": true,
  
  // Terminal font settings (often needs Nerd Font variant)
  "terminal.integrated.fontFamily": "'JetBrainsMono NF'",
  "terminal.integrated.fontSize": 13
}

For ligatures in VS Code, ensure editor.fontLigatures is set to true. You can also use stylistic sets:

"editor.fontLigatures": "'ss01', 'ss02', 'cv01'"

JetBrains IDEs Configuration

Enabling ligatures in JetBrains IDEs (IntelliJ, WebStorm, PyCharm):

1. Open Settings → Editor → Font
2. Select your font (e.g., “JetBrains Mono”)
3. Check Enable font ligatures
4. Adjust size (typically 13-14 for 1080p displays)

For terminal configuration: Settings → Editor → Color Scheme → Console Font

Understanding Nerd Fonts

Nerd Fonts patch regular programming fonts with additional glyphs—file icons, Git symbols, and OS logos. The “NF” suffix indicates a Nerd Font variant (e.g., FiraCode NF, JetBrainsMono NF).

Why use them? Modern terminal tools like Starship or Oh My Posh rely on these icons for rich prompts:

 ~/projects/app  main  node v18.17.0

Install Nerd Fonts from the official repository or via package managers:

# macOS
brew tap homebrew/cask-fonts
brew install --cask font-fira-code-nerd-font

# Windows (Scoop)
scoop bucket add nerd-fonts
scoop install FiraCode-NF

Exploring Variable Fonts

Variable fonts like Monaspace and Recursive offer adjustable weight and width axes. This lets you fine-tune the font without switching families:

// VS Code
"editor.fontVariations": {
  "wght": 400,  // Weight: 300-700
  "wdth": 100   // Width: 75-125
}

Testing Before Committing

Before installing, preview fonts at Programming Fonts or Coding Font. Test with your actual code—what looks good in samples might not work with your syntax highlighting theme.

Conclusion

The right coding font is personal—what works for one developer might not suit another. Start with JetBrains Mono or Fira Code for a safe, modern choice. Experiment with Monaspace if you want cutting-edge features. Remember to install Nerd Font variants for terminal use, and don’t forget to enable ligatures if your chosen font supports them.

Most importantly, give each font a real test drive in your actual workflow. Your eyes will thank you.
