If your note in the right panel looks too narrow and centered, this is usually caused by Obsidian’s Readable Line Length setting or theme constraints. Here’s the fastest way to fix it.

1. Disable “Readable Line Length” (Easiest Fix)

Best for: Most users

Steps:

  1. Go to Settings → Editor → Display
  2. Toggle OFF Readable line length

Result:
Your note expands to use the full available width.
This was confirmed as the simplest working solution in the original discussion. ([Obsidian Forum][1])

2. Adjust Width via Theme Settings

Best for: Users with custom themes (e.g., Minimal, AnuPpuccin)

Some themes override default width behavior and provide their own controls.

Look for options like:

  • “Maximum Preview Width”
  • “Line Width”
  • Theme-specific layout settings

Many themes include built-in controls or require plugins like Style Settings.

3. Use a CSS Snippet (Advanced Control)

Best for: Precise width control

Add a CSS snippet:

body {
  --file-line-width: 850px;
}

How to apply:

  1. Go to Settings → Appearance → CSS Snippets
  2. Create a new snippet file
  3. Paste the code and enable it

This overrides the default editor width variable.
