Most prose on the web uses proportional fonts because that’s what books do. But a blog isn’t a book. The unit of writing is the paragraph, not the page, and reading speed is gated more by the screen than by the typeface.

Monospace flips a few small things in your favor:

  • The column has a natural width — about 80 characters — that you don’t have to think about.
  • Inline code doesn’t visually shift the line.
  • The text looks like a draft, which lowers the stakes of publishing.

The downside is that long-form prose can feel relentless. So far the trade seems fine for short posts.
