What is the Facebook character limit?

Meta doesn't publish one. 63,206 characters is the figure most tools use, and PostDaily enforces it.

How long can a Facebook Reel be?

In Facebook's app, any length since 2025. Through Meta's API, which scheduling tools use, 3 to 90 seconds.

How many photos can a Facebook post have?

Meta states no limit for a multi-photo Page post. PostDaily allows up to 10 in one post.

What is the maximum photo size on Facebook?

Under 10 MB through Meta's API. Facebook's help suggests keeping photos under 15 MB, and PNGs under 1 MB.

How many links can a Facebook Page post?

On Pages where Meta applies the limit, links in 2 organic posts or comments a month, or more on a paid Meta One plan.

Can apps post to Facebook Groups?

No. Meta removed the Groups publishing permission on 22 April 2024, so no scheduling app can post to a Group.

Limits by network

Facebook character limit, photo size and video length

Meta doesn't publish a character limit for Facebook posts. The 63,206 quoted everywhere is the figure scheduling tools enforce, not one any Meta page states. What Meta does document: photos under 10 MB through its API, Reels of 3 to 90 seconds from apps, Story limits, and a monthly link limit on some Pages. Here is every Facebook limit we could source, with the Meta page each comes from.

Every number checked against its source on Nov 12, 2026.

Is 63,206 the real limit?

No Meta page says so. The Graph API's reference for Page posts gives no maximum for the text, and neither do the Pages API guide or Facebook's help centre. The number comes from tools and press articles. PostDaily holds posts to 63,206 because that is the figure the industry works to. Long before it, Facebook folds a post behind See more, and Meta doesn't document where that happens either.

Reels: the app and the API disagree

Since mid-2025 every video posted in Facebook's app is a reel, and Meta's business help says a reel can now be any length or shape. Meta's Reels publishing API, the route every scheduler uses, still takes 3 to 90 seconds, vertical 9:16, at least 540×960 pixels, and up to 30 reels per Page a day. PostDaily posts a longer video as a feed video instead.

Stories

A Story is one photo or one video, with no caption, comments or link sticker when it's published through Meta's API. Meta's Page Stories page gives a video Story two lengths: 90 seconds in its table of specs and 60 seconds in its list of limitations. PostDaily applies 60, the stricter one.

The monthly link limit

On some Pages, Meta now limits links in organic posts. Where it applies, a Page can put links in 2 posts or comments a month, resetting on the 1st, and unused links don't carry over. Paid Meta One plans raise it: 8 on Advanced, 20 on Expert and no limit on Max. Links in comments the Page itself posts count too. A second link in the comments of a post that already has one doesn't, and neither do links to Meta's own apps or in ads. Link in the first comment: what's proven.

Numbers to stop quoting

Two figures you will still find elsewhere are no longer on any Meta page. Feed videos of 10 GB and 240 minutes came from a business help article that now redirects to the reels page, and a 4 MB photo limit was never Meta's: its API says under 10 MB. Apps can't post to Groups or to personal profiles at all: Meta removed Group publishing on 22 April 2024, and the profile feed endpoint doesn't accept posts.

What PostDaily checks, and what it doesn't

Before a post is scheduled, PostDaily checks the text length, the photo count, that photos and a video aren't mixed, image and video files, Reel and Story video lengths, video titles (255 characters) and first comments. It doesn't track your Page's monthly link allowance, so a link post can still be refused or hidden when the allowance is spent. Schedule Facebook posts, Reels and Stories.
