Facebook Post Checker and Character Counter
Facebook lets a post run to 63,206 characters, yet only about 477 of them show before the "See more" link swallows everything else.
Last updated: 2026-07-31
The Facebook post limit is 63,206 characters, a number that comes from an old field size rather than from anything about how people read. You will never reach it. What you will hit is the "See more" link, which folds the post after roughly 477 characters on desktop and earlier on a narrow phone.
Length works against you here more than on any other network. Short posts, in the region of 40 to 80 characters, consistently pull more reactions and comments than the same idea told at length, which puts the practical limit closer to two sentences than to sixty thousand characters.
Use the counter to see where your fold lands, confirm the tagged Pages and hashtags are where you meant them to be, and check the same text against the tighter networks before you cross-post it.

How Facebook compares to the other networks
The hard ceiling is rarely the number that matters. Here is where Facebook sits against every other network Postify publishes to, including the point each one folds your caption behind a "more" control.

Facebook caption tips
- Aim for one or two sentences. Posts of roughly 40 to 80 characters consistently outperform long ones on Facebook, whatever the ceiling says.
- Front-load the point above the 477 character fold. The "See more" click is a real drop-off, not a formality.
- Facebook does not give links a fixed cost the way X does, so a long tracking URL spends every one of its characters. Shorten it before you paste.
- Hashtags do very little on Facebook. One or two for a campaign is fine, a block of them reads as an Instagram caption pasted into the wrong app.
- If the idea genuinely needs length, publish it somewhere with a permalink and use the post to sell the click instead.
Frequently asked questions
How many characters can a Facebook post have?
A Facebook post can hold up to 63,206 characters. It is the highest ceiling of any major network, and almost entirely theoretical: the vast majority of posts that perform well are under 200 characters.
Where does Facebook cut off a post?
The desktop feed collapses a post behind "See more" at around 477 characters. Mobile folds earlier, depending on screen width and whether your text contains line breaks.
What is the ideal Facebook post length?
Short. Posts in the 40 to 80 character range tend to earn the most engagement, and anything under the 477 character fold at least gets read in full. Treat longer posts as a deliberate choice, not a default.
Do hashtags and links count toward the Facebook character limit?
Yes, everything in the composer counts: hashtags, @ mentions of people and Pages, emoji, line breaks and the full text of any URL you paste. Facebook does not compress links into a fixed character cost.
Is the limit different for Facebook Reels and Stories?
Yes. Reels use a much shorter description field than feed posts, and Stories are built around text overlays rather than a caption. This counter measures the standard Page or profile post, which is the field the 63,206 limit applies to.
