What is the character limit on Facebook?

What Meta says, and where it says nothing

All read on 10 October 2026. The list above is what was missing, not a claim that Facebook has no limit. A limit that isn’t printed can still exist; it is just not Meta’s to cite.

The number you will see: 63,206

For a Facebook post, 63,206 characters is the figure guides repeat. It is not on a Meta page we could read, so this page doesn’t give it as Meta’s. It is also the number Mellow Hub checks against, because no smaller one is published. If Facebook’s real limit is lower, the refusal would come from Facebook after Hub’s check, not before it.

What Meta does print: ad text

Meta’s Ads Guide gives text recommendations for an image ad in Facebook Feed: primary text of 50 to 150 characters and a headline of 27, with an image at 4:5, 1440 × 1800 pixels. Those are for paid ads, not for ordinary posts, and they are recommendations.

Other networks do publish a number

The full table across nine networks is on the character limits page, and the free character counter counts one post against all of them.

Posting to Facebook with Mellow Hub

Hub publishes to a Facebook Page you administer, with up to 10 photos or videos in a post, never mixed, and checks the caption against 63,206 characters. A caption over a network’s limit is cut at the last paragraph, line or sentence that fits, and the post’s notes say so, which is how the same post can go to Facebook whole and to X or Bluesky shortened.

Hub is paid: plans start at $19 a month (Solo), after a 7-day trial with a card on file that costs nothing if you cancel before it ends, and a monthly plan's first month is 20% off. Publishing is unlimited on every plan, under a fair-use ceiling that stops automated floods (900 publications a month on Solo). One publication is one post on one account, so a post sent to five networks counts as five. There are no automatic overage charges.
