Quick Takeaways
The Facebook character limit is 63,206 characters per post, a number a Facebook engineer picked as a joke. It's so large it's meaningless in practice, because the feed hides your post behind "See more" after roughly 480 characters. Almost every other Facebook limit you'll read is observed by tool makers, not published by Meta.
The Facebook character limit is 63,206 characters, and the story behind that oddly specific number tells you everything about how little it matters. No platform gives you more room, and no room matters less.
Facebook confirmed the change back in 2011, when its VP of Engineering announced posts could exceed 60,000 characters. An engineer named Bob Baldwin later explained he set the limit to something nerdy: hex(FACE) minus K, or 64206 minus 1000.
That's the real origin. The biggest character limit in social media is an inside joke, and the number that actually governs your reach is one Meta won't tell you.

Where the Facebook Character Limit Came From
The number isn't round because nobody meant it to be. Facebook raised the status limit repeatedly through 2011, from 500 characters to 5,000 in September, then past 60,000 that December.
The final figure was a programmer's pun. Baldwin built it from the hexadecimal spelling of "Facebook," landing on 63,206, and Facebook kept it.
That history matters for one reason. A limit chosen as a joke was never designed around how people read, which is exactly why it's useless as a writing target.
For scale, Facebook itself noted a novel runs about 500,000 characters. Your post cap is roughly a ninth of a novel, which no one is reading in a feed.
Every Facebook Character Limit, and Who Says So
Search this and you'll find tidy tables listing a dozen Facebook limits. They mostly agree, which looks like confirmation but usually means everyone copied one list.
Here's the same information with the part those tables leave out:
Each field, its limit, and whether Meta publishes it.
Only the post limit and the ad specs trace to Meta. The rest are numbers tool makers measured by typing until the field stopped accepting input.
That doesn't make them wrong. It means you should confirm against a live counter rather than trust a table, including this one.

The 480-Character Fold That Actually Matters
Your post collapses behind a "See more" link long before 63,206 characters. Everything past that point only reaches people who already chose to tap.
Meta doesn't publish where the fold falls, which is the tell. Estimates range from about 400 to 480 characters, and they vary because different people measured on different screens.
That range is your real limit. Not the joke number, but the sentence or two visible before a reader decides whether to expand.
Treat the first line as the whole job. It has to earn the tap, because most of your carefully written post is sitting on the far side of a link nobody clicked.
So write the hook first and the depth second. Your ceiling is 63,206, but your budget for attention is closer to 400.
Why Short Posts Beat the 63,206 Ceiling
The fold isn't the only reason to write short. Facebook's own distribution favours posts that hold attention, and a wall of text loses people before the algorithm ever spreads it.
The pattern is consistent across engagement studies. Short posts in the 40 to 80 character range tend to earn the most reactions, while longer posts trade reach for depth.
That doesn't mean long posts are useless. Educational content that earns saves and shares can justify the length, provided the opening line pulls readers past the fold.
The failure mode is the same one every platform punishes. It's a long post whose first sentence was throat-clearing, so nobody expanded it to reach the point.

What to Do With Genuinely Long Content
Sometimes you really do need the room, and Facebook handles that better than its rivals. A post that would fragment into a dozen tweets fits Facebook as a single block.
Structure it for skimming. Open with the payoff, break the text with line breaks, and put your call to action high rather than burying it at character 2,000.
Cross-posting is where the ceiling helps most. Content written for Facebook usually drops onto X, Bluesky, or Threads needing cuts, rarely the reverse, because those platforms cap far lower.
Before you lean on the length, though, try trimming. A 2,000-character post is often a 400-character post wearing a long introduction it doesn't need.
Checking Your Facebook Character Limit Free
Facebook shows a counter in some fields and not others, which is why people paste and hope. UltraWordCounter counts as you type, in your browser, with nothing uploaded and nothing saved.
The free Facebook character counter tracks your draft and shows where your opening lands against the fold. You'll watch the count move as you tighten the hook.
Two passes cover a post. Check that your first line works inside roughly 400 characters, then confirm the whole thing sits under the ceiling.
Everything runs free up to 800 words per session, which covers several posts. Questions about how the counter treats emojis and line breaks are answered on the UltraWordCounter FAQ page.
Anyone drafting a month of content at once will pass the session cap. The Pro plan removes the 800-word limit for $19 a month, or $12 if you pay annually ($144/year), with a 7-day free trial.

Frequently Asked Questions
What is the Facebook character limit for a post?
It's 63,206 characters, which Facebook set in 2011 and has kept since. That's roughly 12,000 words, or about a ninth of a novel, so it's effectively unlimited for normal writing. The practical constraint is the feed hiding your post behind "See more" long before you reach it.
How many characters show before "See more" on Facebook?
Meta doesn't publish an exact number, and observed estimates range from about 400 to 480 characters depending on the device and layout. Treat the first 400 as your real working limit. Whatever sits past that only reaches readers who already decided to expand your post.
Why is the Facebook limit such a strange number?
A Facebook engineer, Bob Baldwin, set it as a joke based on the hexadecimal spelling of "Facebook," giving 63,206. It was never designed around readability, which is part of why it's so much larger than any sensible post length. The number stuck, and Facebook never rounded it off.
Do short or long Facebook posts perform better?
Short posts generally win on engagement, with the 40 to 80 character range often earning the most reactions. Longer posts can work for educational content that earns saves, but only if the opening line pulls readers past the fold. Either way, the first sentence carries the reach.
Does Facebook count emojis and spaces in the limit?
Yes, spaces, line breaks, and emojis all count toward your total. Most emojis consume two characters because of how they're encoded, and some complex ones cost more. Since a post that reads short can measure long, paste it into a counter rather than estimating by eye.
Conclusion
The Facebook character limit is 63,206, and knowing that number helps you almost not at all. It was a programmer's joke, it's larger than any post anyone reads, and the fold that decides your reach is one Meta won't confirm. Write for the fold, not the ceiling.
Earn the tap in your first line, then use only as much room as the idea needs. Paste your draft into UltraWordCounter, watch where your hook lands, and cut the warm-up. Try it free and stop writing for a number a Facebook engineer picked as a pun.
