LinkedIn video upload limits and aspect ratios

LinkedIn publishes three video spec sheets, and they do not say the same thing. Mix them and you will treat an ads ceiling as a feed rule, or a Pages duration as a mobile-app cliff. The file is fine. The sheet was wrong.

The organic share-videos page is the one that governs a normal feed post. Pages and Career Pages are a different upload. Video ads are a third. One conservative export can sit inside all three. That is the useful target, not a rumour about which device you posted from.

Three spec sheets, not one

Surface	Duration	Aspect	Resolution	File size
Organic feed post	15 minutes max; min 3s desktop, 2s mobile	1:2.4 – 2.4:1	256×144 – 4096×2304	5 GB (min 75 KB)
Pages / Career Pages	10 minutes max	1:2.4 – 2.4:1	256×144 – 4096×2304	5 GB (min 75 KB)
Video ads	3s – 30 minutes	Named ratios including 16:9, 1:1, 4:5, 9:16	9:16 bounded 360×640 – 1080×1920	75 KB – 500 MB

Ads also require MP4 (H.264 or VP8) and a frame rate under 30 fps. Organic allows 10–60 fps. If one file has to clear ads as well, stay at 25 fps.

The organic row is what most people mean by "LinkedIn video." It does not document a 10-minute mobile maximum. The device split on that page is the minimum: three seconds from desktop, two from the app. Third-party blogs still repeat a 10/15 split as if it were the feed rule. That number lives on the Pages sheet, not on the share-videos page.

The 9:16 window of 360×640 to 1080×1920 lives on the ads sheet. Organic posts are documented as a range (1:2.4 to 2.4:1), which includes 9:16, 4:5, 1:1 and 16:9 without naming them as a closed list.

Which ratio performs is a separate question. I have not found any LinkedIn-published statement on video ranking weights; treat "which ratio wins" as an account-level empirical question. Let your own post data choose the aspect ratio is the method.

What the organic page actually allows

The organic sheet adds two numbers the table above does not: frame rate 10–60 fps, and bit rate 192 Kbps – 30 Mbps.

1:2.4 is taller than 9:16 (0.42 vs 0.56). 2.4:1 is wider than 16:9 (2.4 vs 1.78). So 9:16, 4:5, 1:1 and 16:9 all sit inside the organic range. You are not limited to four named shapes on a feed post. You are limited to that range.

The resolution cap is the one that actually bites a modern export. 4096×2304 is a landscape 4K canvas. A 4K vertical file at 2160×3840 exceeds 2304 on the long edge. A 1080×1920 9:16 file does not. LinkedIn does not document what happens to a file above the range — reject, transcode, or silent accept — and I am not going to guess. Export at a size the sheet names.

Where 1080×1920 still belongs

If you also run the same master as a video ad, the ads sheet is stricter on 9:16: maximum 1080×1920. Organic will take that file. Ads will take that file. Pages will take that file on ratio and resolution.

That is why 1080×1920 for 9:16 is still the default, even though organic would theoretically accept a taller or larger canvas inside 4096×2304. One deliverable, three sheets. You give up a 4K vertical export that the organic range already looks hostile to, and you stay inside the ads 9:16 window without a second render.

Do any upscaling or restoration work you need during production. Then export the LinkedIn deliverable at 1080×1920 (9:16) or 1080×1350 (4:5). Conflating those steps is what puts files out of spec.

4:5 sits in the organic range and is the ads-recommended vertical for some placements. 16:9 at 1920×1080 sits in all three. Pick one per format and keep it fixed across the series.

Duration: 15 minutes, 10 minutes, and the rumour

Build duration against the sheet that will actually receive the file.

• Feed post from the share box: 15 minutes, per the organic page.
• Pages / Career Pages media (Life tab, What We Do): 10 minutes, per the Pages page. This is a different upload, not a mobile-app variant of the feed.
• Video ads: up to 30 minutes, with LinkedIn recommending 15–30 seconds so the file qualifies for more placements. Do not treat the ads ceiling as a feed length.

If a cut has any chance of being reused as Pages media, keep it under 10 minutes. That is a reuse constraint, not a hidden mobile rule. A 12-minute talk is a valid feed post on the documented organic spec; it is not a valid Pages video.

One export that clears the documented windows

Here is the spec I would default to for LinkedIn video, chosen so that a single render is valid as a feed post, as Pages media, and as a 9:16 ad:

1. Aspect ratio: 9:16 for short-form, 4:5 for feed-native pieces you want taller than square without going full height. Pick one per format and keep it fixed across the series.
2. Resolution: 1080×1920 for 9:16, 1080×1350 for 4:5. Inside the organic range and inside the ads 9:16 / 4:5 windows.
3. Duration: under 10:00 if the file might also land on a Page. Under 15:00 if it is feed-only.
4. Captions burned in. LinkedIn video autoplays into a feed that people scroll in offices. Sound-off legibility is not a nice-to-have on this platform.
5. Frame rate 25 fps, consistent across the timeline. Mixed source rates produce judder that is invisible in a preview scrubber and obvious in a feed. 25 fps sits inside organic (10–60) and under the ads ceiling (less than 30). If a clip arrives at 24, handle it deliberately rather than letting the render decide — the 24 fps on a 25 fps timeline problem is the specific version of this.
6. No platform watermark. A file carrying another app's watermark reads as recycled on a professional network even where it is not against the rules.

That set is deliberately conservative. It gives up the theoretical 4K vertical canvas and the full 15-minute feed ceiling when the file might be reused. In exchange every file matches the strictest sheet you actually use.

Producing it without re-rendering three times

The version of this that gets expensive is producing separate masters per ratio. One 9:16 render, one 4:5 render, one 16:9 render, each with its own caption pass and its own round of notes.

The cheaper shape is one timeline, several outputs. Versely's editor is EDL-based — a single timeline you re-render rather than a set of separate projects — so a change to the aspect ratio is a re-render of the same edit. That is the mechanic behind reframing one edit into three aspect ratios.

The editor's 480p preview pass is free and carries a short per-user cooldown, which makes it the right place to check framing, caption safe-areas and duration before committing to a final export. The final export is charged once regardless of how many clips are on the timeline — the arithmetic is on editor previews and final export. Default output is 25 fps, and there are no watermarks on any plan, so nothing in the delivered file needs cleaning up before it goes to LinkedIn.

Before publishing, run the pre-publish check: duration against the sheet that will receive it, dimensions at 1080×1920 or 1080×1350, captions legible at feed size, first frame not a black flash.

FAQ

Which aspect ratio should I use for LinkedIn video?

The organic page allows 1:2.4 to 2.4:1 and does not recommend among the shapes inside that range. Talks and screen recordings need the horizontal room; short-form cuts do better vertical. Pick one per format, run it for enough posts to see past the variance, and let your own data decide rather than a general rule. The wider vertical video spec reference covers how LinkedIn's numbers compare with the other destinations you are probably publishing to.

Why do some guides say 10 minutes on mobile and 15 on desktop?

Because they are blending sheets. The organic share-videos page documents a 15-minute maximum and a 3s/2s minimum split by device. The 10-minute maximum is on the Pages / Career Pages spec. If a 12-minute file fails, check which uploader you used before assuming the mobile app silently enforces a different feed cap.

Is 4K vertical worth exporting for LinkedIn?

No. Organic documentation tops out at 4096×2304. A 4K vertical export at 2160×3840 exceeds 2304 on the long edge, and ads bound 9:16 at 1080×1920. Do any upscaling during production, then export the deliverable at 1080×1920. You lose nothing visible at feed viewing size and you stay inside the documented windows.

Do I need separate versions for the company page and personal posts?

The organic feed spec is the same either way. Pages media (Life tab, What We Do) is the 10-minute sheet. What usually differs is the cut: company page video tends toward the longer, more produced end, and personal posts toward the shorter vertical end. Check which surface will actually host the file.
