LinkedIn video specs 2026: sizes, length and a demo format

LinkedIn video specs — 16:9, 1:1, 4:5 and 9:16 at up to 1080p, under 15 minutes, 5 GB — and a device-mockup demo format that works in a B2B feed.

Published September 4, 2026

LinkedIn is the one feed where a laptop mockup outperforms a phone: the audience is buying software for work, and a MacBook or a Pro Display XDR running your dashboard reads as "serious tool" in a way a phone does not. The feed also rewards vertical-ish video — 4:5 and 1:1 take more screen than 16:9 on mobile — which changes how you compose the device.

LinkedIn video specs (September 2026)

Aspect ratios 16:9, 1:1, 4:5 and 9:16 (feed and ads)
Resolution 256 × 144 minimum to 4096 × 2304 maximum; 1080p recommended
Length Up to 15 minutes for organic posts (ads up to 30 minutes)
File size Up to 5 GB for posts; 500 MB for ad videos
Format MP4 recommended; H.264 with AAC audio
Captions Strongly recommended — most feed views are muted

LinkedIn accepts a wide range of sizes, but the feed crop is what matters: 4:5 (e.g. 1080 × 1350) and 1:1 (1080 × 1080) occupy the most vertical space on a phone without being cut off the way 9:16 sometimes is in the feed.

The export settings that fit LinkedIn

For a feed post, compose at 4:5 with the laptop turned three-quarters and the headline in the top fifth of the frame; export the 4:5 preset and let LinkedIn scale it. For a company-page hero or an article embed, 16:9 at 1920 × 1080 is right. Length: 20–45 seconds — LinkedIn viewers tolerate slightly longer than X, but the first three seconds still decide whether they stay. Add a text shot with the problem statement before the demo, and a logo shot at the end.

A LinkedIn demo that people actually watch

Making it in OpenMock

  1. Open OpenMock in a desktop browser and set the canvas ratio to 4:5 (or 1:1) in the top bar.
  2. Pick a device (or the frameless screen) and drop your screenshot or screen recording onto it.
  3. Use the MacBook Pro 14-inch with the lid at about 105°, and keyframe a slow sideways drift across the screen recording.
  4. Add a text shot for the hook and a logo shot at the end if you want a branded close; both are shots on the same timeline.
  5. Export video with the 4:5 — 1920×2400 preset (LinkedIn downscales to 1080 × 1350) or 1:1 — 1080×1080. Free exports are 720p/30 fps with a watermark; Pro gives you the full-resolution, watermark-free file.

FAQ

What aspect ratio should a LinkedIn product video be?

4:5 (1080 × 1350) or 1:1 (1080 × 1080) for feed posts — they take the most mobile screen without cropping. 16:9 (1920 × 1080) for company-page heroes and article embeds. 9:16 is accepted but can be cropped in the feed.

How long should a LinkedIn app demo be?

Twenty to forty-five seconds for a feed demo. LinkedIn allows up to 15 minutes, but a product clip should show one workflow and stop.

Does a laptop mockup really perform better than a phone on LinkedIn?

For B2B software, yes in our experience and in most practitioners' — the device signals the context of use. If your product is a mobile app, show the phone; if it is used at a desk, show a MacBook or monitor.
