Meta’s current guidance treats new Facebook videos as Reels: since the 2025 change, you no longer choose between a video upload and a Reel. Meta says Reels have no length or format restrictions, while an updated Help Centre page says they can be any length or orientation.
That broad policy is not a technical export-specification sheet. The official organic guidance reviewed does not set a universal resolution, codec, container, frame rate or file-size ceiling, so do not treat numbers from an older page or an unofficial roundup as current platform rules.
What changed about Facebook video uploads
Meta announced on 17 June 2025 that Facebook would share all new videos as Reels, removing the need to choose between uploading a video and uploading a Reel. Meta’s announcement was updated on 14 July 2025. The important practical change is the publishing route: new video posts are being brought under the Reels experience rather than requiring a separate decision about format.
The change does not mean every older screen, help article or creator workflow was updated at once. The Help Centre’s updated guidance on exploring and watching Reels notes the Videos tab change and says Reels can be any length or orientation. Another Help Centre page still contains an “up to 90 seconds” statement. That older wording conflicts with the later announcement, so it should not be used as a universal current limit.
For an editor preparing an ordinary, unpaid Facebook post, the useful starting point is therefore the current Reels policy, not an old video-upload checklist copied from a different publishing era. Check the live publishing interface as well: features and labels can vary while Meta rolls out changes, and the interface is where you will see whether the account can complete the upload you intend.
This is a question about publishing to Facebook, not the technical demands of a continuous YouTube broadcast. If your wider workflow includes an always-on YouTube channel, our guide to hosting a stream on AWS from India covers a separate set of operational decisions; do not transfer its streaming assumptions to an ordinary Facebook Reel upload.
Current Reel length and orientation guidance
Meta’s statement that Facebook Reels have no length or format restrictions is broad platform guidance. The updated Help Centre page is more explicit about orientation: it says a Reel may have any length or orientation. Taken together, these sources do not support a universal rule that an organic Facebook video must be vertical or must stop at a particular duration.
That distinction matters when someone asks, “How long can a Facebook video be?” A lingering page that says Reels are up to 90 seconds may appear authoritative because it is still hosted by Facebook. But it is inconsistent with Meta’s later 2025 announcement and the updated discovery page. Read it as legacy or conflicting help text, not as a current limit that applies to all new organic Reels.
Orientation is similarly easy to overstate. A vertical edit may suit a phone-first Reel, but the current organic guidance does not say every video must be 9:16. A landscape recording, square edit or portrait clip should be evaluated in the context of the viewing experience and the content, rather than rejected on the basis of an unsupported universal requirement.
Duration and orientation policy are also different from practical editorial choices. A long teaching session might be easier to follow with clear chapter cards and a deliberate opening; a short announcement may benefit from getting to its point quickly. Those are audience and creative decisions, not evidence that Facebook imposes a matching hard cutoff. If you repurpose a looping programme, consider whether repeated footage is suitable for a social post; our discussion of replaying the same videos on a 24/7 YouTube channel is about that distinct channel context, not Facebook’s upload limits.
Supported formats and practical export checks
“Any format” in Meta’s announcement should not be mistaken for a list of file extensions, codecs or encoding settings. It describes the absence of a stated length or format restriction for Reels at the policy level. The official organic pages reviewed do not provide a universal technical table specifying accepted containers, codecs, resolution, frame rate or a maximum file size.
That means there is no evidence here for publishing a precise Facebook-wide maximum such as a particular number of megabytes, a mandatory pixel dimension or a required codec. The upload interface may apply technical validation, and support for a particular file can depend on the current product workflow. If an upload is refused, use the error message and current Facebook guidance rather than guessing that an unverified number applies to every account and placement.
Before exporting, make practical checks that do not depend on an invented platform limit:
- Confirm the image is the intended orientation and that the important subject remains visible when previewed on a phone.
- Watch the beginning, middle and end of the exported file to catch a black opening, frozen final frame or accidental edit gap.
- Check that speech and music are audible at a sensible level and are not clipped or unexpectedly out of sync.
- Export the intended version and filename, then keep a clean source copy in case you need to revise the edit.
- If the interface reports a format problem, try a conventional export supported by your editing application and test again, without assuming that one container or codec is a published universal requirement.
These are quality-control checks, not claims about Meta’s hidden or changing acceptance thresholds. A technically valid file can still look poor in the feed if text is tiny, the subject is cropped by the preview, or the first frame does not explain what the viewer is seeing. Review the actual post preview before publishing.
Policy is not the same as a technical recommendation
A useful way to read “specs” is to separate three different kinds of information: platform policy, creative recommendation, and upload validation. Confusing them is how an ad recommendation becomes an alleged rule for every organic post, or how an older Help Centre line survives after the product changes.
| Information type | What the available guidance says | How to use it |
|---|---|---|
| Organic Reel policy | Meta says no length or format restrictions; updated Help Centre guidance says any length or orientation | Treat this as the current broad publishing position, while checking the live interface for your upload |
| Reels ad creative | Meta recommends 9:16 video, audio and key messages kept in a safe zone | Apply it when designing paid Reels ads, not as a mandatory organic-video export rule |
| Technical encoding | The official organic pages reviewed do not give a universal resolution, codec, container, frame-rate or file-size table | Do not publish exact limits unless a current primary source states them for the relevant workflow |
| Legacy help text | A Help Centre creation page retains an “up to 90 seconds” statement | Note its conflict with the later policy rather than repeating it as a current universal cap |
For paid placements, Meta’s Reels advertising guidance recommends vertical 9:16 creative, audio, and keeping important messages within the safe zone. That is sensible ad composition advice: interface controls can sit over parts of the image, so essential text should not be placed where those controls obscure it. It is not proof that an organic post in another orientation is disallowed.
This separation also helps when an editor sends you a “Facebook specs” sheet. Ask what the sheet refers to: an organic Reel, a paid placement, a particular editing workflow, or an older product. A recommendation can be useful without being a platform rule. A technical requirement needs a source that actually gives the requirement, and that source should match the publishing context.
How to prepare and publish a video
Start by deciding what the post is for and where viewers are likely to see it. If a person needs to read a title card or follow a demonstration on a phone, preview the composition at phone size. If the material was recorded in landscape, do not crop it to portrait automatically; first check whether that would cut out a speaker, product or important on-screen detail.
Next, choose a clean edit and make a single review export. Watch the exported file rather than relying only on the editing timeline. Check that the audio begins when expected, the video does not stop early, and any burned-in text is legible. If accessibility matters to the audience, add captions or provide them through Facebook’s caption workflow rather than assuming that text embedded in the image is equivalent.
Facebook Help Centre explains that you can add captions to a video posted to a profile or Page by uploading a SubRip (.srt) file; see its caption instructions. This is a caption-file capability, not a video encoding specification. Keep the caption file aligned with the final edit, and review the result after upload because a timing mismatch can be distracting even when the words themselves are correct.
Then publish through the current interface. Select the intended profile or Page, choose the video, add the post text and any available captions, and inspect the preview. If the editor presents a Reel publishing flow, that is consistent with Meta’s move to share new videos as Reels. Follow any validation message the interface provides; do not override it based on a copied spreadsheet that may describe a previous product state.
After publishing, view the post as a viewer would. Check the crop, audio, captions and opening frame on a mobile device if possible. If you are also managing long-running YouTube programming, keep the operational plans separate: a playlist stream schedule addresses continuity across a broadcast, whereas this Facebook workflow is about a single published video.
Spot outdated or conflicting limit guidance
When you see an exact limit online, first identify who published it and when. Then identify the context: organic video, Reels ad, Story, a particular upload device, or an older “video” product. A number without those details is difficult to apply, and a Help Centre page can remain visible even when a later platform announcement changes the policy.
The specific conflict to recognise is the “up to 90 seconds” line on Facebook’s older Reel creation page. The page’s wording conflicts with Meta’s subsequent June 2025 announcement that Facebook Reels would have no length or format restrictions, and with updated Help Centre language saying Reels may be any length or orientation. Do not repeat the 90-second text as a current universal limit without explaining that conflict.
The reverse mistake is to stretch Meta’s broad statement into details it does not provide. “No length or format restrictions” does not document every file type, technical resolution or maximum upload size for every device. Nor does a recommendation for 9:16 ad creative establish an organic rule. Where a primary source is silent, the responsible answer is to say so and direct the reader to current in-product validation.
If you run into contradictory advice, record the page title and date you checked, then follow the newest relevant official guidance for the exact workflow. If the point affects a campaign or a deadline, test the planned file in the publishing interface before the last minute. That check is more useful than treating a confident third-party table as definitive when it does not cite a current Meta source.
Pre-publish checklist
Use this checklist for a routine organic Facebook video. It is designed to catch avoidable publishing errors without inventing technical limits that the cited Meta pages do not set.
- Confirm the context. You are publishing an organic profile or Page video, not creating a paid Reels ad. If it is an ad, follow the relevant ad creative guidance separately.
- Use current policy language. New Facebook video sharing is being consolidated under Reels. The current broad guidance says any length or orientation; do not treat the older 90-second line as a universal cap.
- Choose composition for the content. Keep the subject and essential details visible in the intended viewing context. Vertical may be a useful creative choice, but the organic guidance reviewed does not make it mandatory.
- Review the actual export. Watch it through, check sound and sync, and verify the first and last frames. Confirm that captions, graphics and any text are readable.
- Add captions where useful. If using an SRT file, make sure it matches the final edit and inspect its timing after upload.
- Read the interface response. Follow any current validation or error message from Facebook rather than applying an unsupported file-size, resolution or codec number from an old checklist.
- Preview the published post. Check orientation, crop, sound and captions from the viewer’s perspective before considering the job finished.
When you publish the same source in more than one place, keep a note of the version and any changes made for each destination. A Facebook post and a scheduled YouTube broadcast are different products, so the technical and operational instructions for one should not be assumed to govern the other. For a continuous programme, a comparison of Raspberry Pi and VPS approaches can help with the separate question of keeping a YouTube playlist running.

FAQ
How long can a Facebook video be?
Meta’s current announcement says Facebook Reels have no length restrictions, and its updated Help Centre discovery page says Reels can be any length. An older creation page still says “up to 90 seconds”; it conflicts with the later guidance and should not be presented as the current universal limit.
Does a Facebook video have to be vertical?
The updated Help Centre page says Reels can have any orientation. Vertical 9:16 is a recommendation for Reels ads, not a universal organic-video requirement in the sources reviewed.
What resolution, file size or codec should I use?
The official organic pages reviewed do not specify a universal resolution, maximum file size, codec, container or frame rate. Check the current publishing interface and its validation messages for the file you are uploading rather than relying on unverified exact limits.
Can I add captions to a Facebook video?
Yes. Facebook Help Centre documents uploading a SubRip (.srt) caption file for a video posted to a profile or Page. Match the file to the final edit and review the caption timing after publishing.
