Facebook post limits: post text length, image size and video length
Facebook is the most forgiving network to plan for: a very long text limit, text-only posts that publish fine, and images in any shape — it fits the image rather than refusing it. The limit that matters is the ~480 characters shown before “See more”.

These are the limits for publishing through a scheduling tool — Facebook’s publishing API — and they are the same rules our editor checks as you write. Posting by hand in the Facebook app can allow a little more on some limits.
Planning a Facebook post
- Keep the point of the post inside the first ~480 characters; the 63,206-character limit is not a target.
- Links are clickable and generate a preview card, so a link post needs no image of its own.
- Up to 10 photos or videos can go in one post.
Pages, not profiles
Scheduling tools publish to Facebook Pages — the business presence a brand runs — not to personal profiles. Meta’s publishing API has never posted to personal timelines, and it withdrew posting to groups in 2024. If a client’s brand lives on a personal profile, it needs a Page before its posts can be scheduled.
Whoever connects the Page needs a role on it with permission to publish. For agencies, the client usually grants that through their business settings, so nobody shares a password.
Text, links and the “See more” line
A Facebook post can run to 63,206 characters, which in practice means no limit at all. The number that matters is the ~480 characters shown before “See more” — more than any other network, but still the first few lines. Put the point there.
Facebook is one of three networks where a text-only post publishes fine, and it treats links well: a link is clickable and draws a preview card from the page it points to — its title, description and image. A post that only needs to send people somewhere needs no image of its own.
Images in any shape
Facebook fits whatever shape it is given rather than refusing it, as long as the image is at least 320 px wide. That makes it the most forgiving network for reusing creative — but not every shape uses the feed well.
- 4:5 portrait (1080 × 1350 px) takes the most room in a mobile feed
- 1:1 square (1080 × 1080 px) is the safe choice when the same image goes to Instagram
- Very tall or very wide images are shown smaller, with space around them
Up to 10 photos and videos can go in one post. Facebook lays several images out as a collage, so the first one or two are the ones people see largest.
Video
Facebook takes video from 1 second up to 4 hours long — far more than any feed viewer will watch. Most video in the feed starts playing silently, so burn in captions or make sure the first seconds work without sound.
Vertical video fills the screen on a phone; square and 4:5 sit comfortably in the feed on both phone and desktop. If one edit has to serve Facebook and Instagram, 4:5 is the shape that suits both feeds.
