Facebook Feed video length limit in 2026: 4 h max per upload, 1 min–3 min optimal range. Why max ≠ best-performing.
Facebook Feed max video length: 4 h. Best-performing range: 1 min–3 min.
Facebook Feed's maximum video length in 2026 is 4 h per single upload. The recommended optimal length — the range where Facebook Feed's algorithm reliably rewards completion — is 1 min–3 min.
The gap between "max allowed" and "best performing" matters. Facebook Feed surfaces the max length as a ceiling, not a target. Posting at the maximum length usually under-performs shorter cuts because Facebook Feed ranks on completion rate, not raw watch time. A 60s clip watched to the end out-performs a 600s clip dropped at 90s every time.
What happens if you exceed the limit: Facebook Feed's uploader rejects the file with a "video too long" error. For long-form sources, trim the clip to the recommended range before upload — auto-trim tools that cut at the time mark and re-encode will work, but lose 1 generation of quality.
Note: 240min cap is widely cited; SRT side-car upload supported.
If you're repurposing from a long-form source — podcast, webinar recording, long YouTube video — the highest-leverage conversion path is: (1) transcribe the full source, (2) score segments by hook strength + payoff density, (3) cut the top-scoring 1 min to 3 min clip, (4) reframe to 16:9 ratio, (5) burn captions. The comparison table below shows length limits across the platforms most creators cross-post to alongside Facebook Feed.
Facebook Feed compared against 4 platforms most creators publish to alongside it.
| Platform | Max video length | Category |
|---|---|---|
| Facebook Feed | 4 h | social-mixed |
| Instagram Feed | 1 min | social-mixed |
| 10 min | social-text | |
| YouTube | 12 h | video-long |
| X (Twitter) | 2 min | social-text |
4 h per upload in 2026. Most creators ship in the 1 min–3 min range for best algorithm performance.
Facebook Feed enforces the 4 h cap at the uploader level. Trim before upload, or split the source into multiple posts.
1 min–3 min is the sweet spot — long enough for a real payoff, short enough to keep completion rate high.
Not on standard accounts. The 4 h cap applies to most uploads as of 2026-05.
