Facebook Post Character Limit 2026: All Hidden Caps

Facebook will let you type 63,206 characters into a single post. That's a novella. Nobody reads a novella in their feed, and Facebook knows it — which is why almost everything after the first few hundred characters gets folded behind a "See more" link. The gap between what you can post and what anyone actually sees is where most Facebook copy goes wrong, so that gap is what this article is really about.

Yes, the 63,206 Limit Is Real (No, You Won't Use It)

The number sounds invented, but it's accurate: 63,206 characters per post, the biggest allowance on any major social platform. For scale, comments cap at 8,000 and a single Messenger message can carry 20,000.

In practice, that ceiling is trivia. Long-form storytelling might justify a few thousand characters. A detailed announcement, maybe a thousand. But a post that genuinely needs tens of thousands of characters is a full article, and full articles belong on a blog or in a note — not crammed into a status update. The limit exists so you never have to think about it. What you do have to think about is the cutoff.

What the Feed Actually Shows Before "See More"

Here's the number that matters. On desktop, the feed displays roughly the first 477 characters of a post before collapsing the rest. On mobile, where most of your audience is scrolling, the cutoff lands around 125 characters. Attach an image and the visible text shrinks even further.

So a "63,206-character post" is really a 125-character post with an optional appendix. Most people scroll on without ever tapping through. Curious where your own draft gets cut? Paste it into the Facebook character counter and watch the count while you trim.

The Fields Where Facebook Actually Squeezes You

Now the flip side. While posts get a comically large allowance, several fields are genuinely cramped — and these are the ones people hit in real life.

The bio is the harshest one: 101 characters to describe yourself. Every word has to earn its spot.

Ads are where counting characters turns into money. The headline technically stretches to 255 characters, but Facebook recommends 40 to avoid truncation — same story with primary text, where 125 characters is the safe zone even though there's no strict cap. Writing to the recommended figure, not the maximum, is what keeps your copy intact. Run ad text through the character counter before it goes live.

Profiles and Pages Follow Different Rulebooks

A personal profile and a business Page look similar, but their fields don't line up. Profiles keep everything tight: 50 characters for the name, 101 for the Intro, 101 for the About text.

Pages get a different set of boxes:

• Page name — 75 characters, a bit more generous than the profile's 50
• Short description — 155 characters
• Full description — 255 on paper, but only around 155 display before it gets cut
• Mission — 244 characters
• Company overview — 50,000 characters, effectively unlimited

If you run a Page, the short description is the field worth sweating over. It's what shows up most often, and 155 characters go fast.

So How Long Should a Post Actually Be?

Shorter than you think. The engagement research is blunt: posts under 80 characters pull roughly 66% more engagement than longer ones. For link posts, the sweet spot narrows to somewhere between 40 and 80 characters.

Does that mean long posts are dead? No. Anything under 250 characters holds up fine, and posts beyond that can still land when there's a genuine story to tell. The catch is the mobile cutoff from earlier — whatever your total length, the first 125 characters have to carry the hook, because that's all most readers see before deciding whether to tap through.

Beyond raw length, the usual levers still apply. A strong image buys attention that text alone won't. A question at the end tends to pull comments. And test — your audience might happily read long posts even when the averages say otherwise.

Frequently Asked Questions

What is the Facebook post character limit?

Facebook posts can be up to 63,206 characters — the roomiest cap of any major social network. The feed cuts posts off much sooner, though: after roughly 477 characters on desktop and about 125 on mobile, readers have to click "See more" to keep reading.

How long should a Facebook post be for engagement?

Short wins most of the time. Posts under 80 characters see about 66% higher engagement, and 40-80 characters is the sweet spot for link posts. Longer storytelling posts can still work — just make sure the hook lands in the first 125 characters.

What is the Facebook comment character limit?

Comments max out at 8,000 characters, so there's plenty of room for a detailed reply. Shorter, focused comments still tend to earn more responses.

How many characters can a Facebook bio have?

The Intro on a personal profile allows just 101 characters. Business Pages get more room: 155 characters for the short description and 255 for the full one.
