Writing for Threads

Threads posts are short by design (500 characters) and the feed rewards replies more than likes. Opinions, questions and one-liners do better than announcements.

Threads has no text formatting. Unicode styled characters work and Threads keeps line breaks, but with a 500-character limit a bold first line is usually enough.

Post formats that work in 2026

  • The list: "3 things I got wrong about…": the first line names the count.
  • The contrarian take: one belief, why it is wrong, what to do instead.
  • The story: a specific moment, what changed, the lesson in one line.
  • The question: a real one you want answered: comments follow.
  • The how-to: steps, short lines, no fluff.
