Long Limits, Short Attention
Facebook technically allows enormous posts, but the feed truncates them around 477 characters behind “See more” — and engagement studies consistently show short posts of 40–80 characters get the most interaction. Write long only when the story earns it, and make the first sentence carry the hook either way.
Tips for Posts and Ads
- Put the point before the fold. Assume nobody clicks “See more” unless the opening earns it.
- Ads get cut sooner than posts. Keep primary text near 125 characters so the full message shows on mobile placements.
- Your Intro is 101 characters — one clear line about who you are beats a row of emoji.
- Break up long posts with line breaks; a wall of text is the fastest way to get scrolled past.
Does Facebook cut off long posts?
No — the full text stays, but readers must click “See more”. The real limit is attention, not characters.
What post length gets the most engagement?
Short. Posts around 40–80 characters consistently earn the highest engagement in published studies — the 63,206-character ceiling is a technical limit, not a goal. Save long-form writing for articles and use the post to earn the click.
