The widest, oldest audience

How to Use Video on Facebook in 2026: Reels, Feed Video and a Broader Audience

Facebook is frequently written off by people making content for a younger audience, which is precisely why it is often the least competitive place to reach an older, higher-intent one. The demographics genuinely differ from TikTok's, and content that lands on one will not automatically land on the other. If your customer is over forty, this is likely the most underpriced attention available to you.

Short guide — real, deliberately brief

The formats and what they are for

FormatAspect & sizeDurationWhat matters
Reels9:16 — 1080×1920Up to 90 secondsThe reach surface, behaving broadly like Instagram Reels and sharing much of the same infrastructure.
Feed videoSquare (1:1) or vertical (4:5) take the most feed space; 16:9 is supportedLonger form is supported and viable here in a way it is not on short-form-only feedsFacebook retains a genuine audience for longer video, particularly explanatory and narrative content.

Platform specifications and duration limits change, sometimes without announcement. The figures here were correct when written and the first-party documentation linked at the foot of each guide is the authority — check it before a launch rather than trusting any third-party article, including this one.

01

Captions are not optional

Silent autoplay is the default viewing mode, and the audience skews toward contexts where sound is inconvenient. A video without on-screen text is a video most people will never hear.

This is the single highest-leverage change most accounts can make here, and it is entirely mechanical.

  • Burn captions in rather than relying on automatic ones.
  • Keep captions large; the audience skews older and screens are often held further away.
  • Front-load the subject in text on the opening frame.

02

The audience is different, so the content should be

The same video that performs on TikTok often underperforms here, and the reason is usually pacing and reference rather than quality. Faster is not automatically better for this audience, and content that assumes fluency in short-form conventions can simply read as confusing.

Clear, complete, slightly slower content with an explicit point tends to travel further than the same idea cut for a younger feed.

  • Say the point plainly rather than implying it.
  • Longer is genuinely viable here; do not compress out of habit.
  • Groups remain a real distribution mechanism and behave nothing like the main feed.

Safe zones

Where the platform's own interface sits over your frame. Compose around these rather than discovering them after export.

  • Reels carry the caption, page name and audio credit along the bottom and an action column on the right, much like Instagram.
  • Feed video shows a page header above the media, leaving the frame itself largely clear.
  • Keep essential text out of the lower fifth on Reels, where the caption can expand over several lines.

Rhythm

Deliberately qualitative. Anyone quoting you an exact optimal posting frequency made it up.

Reels
Regular posting works, though the format rewards quality over volume more than TikTok does.
Feed video
Less frequent and more substantial. This is where longer explanatory content earns its place.

Where the pipeline helps on Facebook

Specific to this platform, not generic

  • Captions are part of assembly, not a manual pass afterwards.
  • A Facebook cut can be planned at a different pace from the TikTok cut of the same idea rather than being the identical file.
  • The 9:16 Reel and the 4:5 feed version come from one master, recomposed rather than cropped.

Facebook questions

How long can a Facebook Reel be?
Up to 90 seconds. Feed video supports considerably longer durations, and Facebook retains a real audience for longer explanatory and narrative video that most short-form-only platforms do not.
What is the best video size for Facebook?
9:16 at 1080×1920 for Reels. For feed video, square or 4:5 vertical occupy the most space as someone scrolls, which means more time on screen than a 16:9 upload.
Do I need captions on Facebook video?
In practice, yes. Video autoplays muted and a large share of viewing never turns sound on, so anything essential that exists only in audio will be missed by most of the audience.
Is Facebook still worth posting video to?
It depends entirely on who you are trying to reach. The audience skews older than TikTok's, which makes it less competitive and often better value if your customer is in that demographic — and a poor fit if they are not.
