Obsidian: Custom Fonts Like a Pro

So, you want to wrestle Obsidian’s fonts into submission, huh? Ditch the app’s built-in settings and take full control with CSS? Good. That’s the kind of power move I respect.

Obsidian lets you inject your own CSS snippets, meaning you can customize every inch of its typography—interface, text, monospace, even the default font size. Here’s how you seize the reins:

1. The Interface Font (Menus, Sidebar, UI Elements)

This governs the non-note parts of Obsidian—buttons, modals, sidebars, the whole bureaucratic infrastructure. Override it like so:

body {
  --font-interface: "Your Interface Font", sans-serif;
}

2. The Text Font (Your Actual Notes)

This is where your ideas live and breathe. If the default font feels like a corporate drone whispering in your ear, change it:

body {
  --font-text: "Your Text Font", serif;
}

3. The Monospace Font (Code Blocks & Inline Code)

For those moments when precision matters—code snippets, command-line poetry, or just making something look important:

body {
  --font-monospace: "Your Monospace Font", monospace;
}

4. Global Font Size (Mimics Obsidian’s “Font Size” Setting)

Obsidian defaults to 16px. But who said you have to follow the herd?

body {
  --font-text-size: 18px; /* Or whatever suits your eyeballs */
}

Putting It All Together

Here’s a full CSS snippet you can drop into vault/.obsidian/snippets/custom-fonts.css:

body {
  --font-interface: "Inter", sans-serif;
  --font-text: "Georgia", serif;
  --font-monospace: "Courier New", monospace;
  --font-text-size: 18px;
}

Activate it in Settings > Appearance > CSS Snippets, and boom—welcome to your new custom-typed reality.

Obsidian isn’t just a note-taking app; it’s a canvas for your thoughts. Why settle for someone else’s design choices? Shape it into something that feels right.
