The short answer
A LinkedIn video posted from your profile can be 3 seconds to 15 minutes long (2 seconds from the mobile app) and 75 KB to 5 GB. Any shape from 2.4:1 (wide) to 1:2.4 (tall) works, so 16:9, square, 4:5 and 9:16 videos all fit, at 256 × 144 up to 4096 × 2304 pixels, 10 to 60 frames per second.
LinkedIn Pages have a shorter limit of 10 minutes. Videos sent through apps such as schedulers follow LinkedIn's developer limits instead: MP4, 3 seconds to 30 minutes, 75 KB to 500 MB.

LinkedIn doesn't ask for one exact video size. It gives a range of shapes, lengths and file sizes, and the limits change depending on where the video comes from: your profile, a company Page, or an app that posts for you. Here's what LinkedIn's own Help Center and developer documentation say, checked in November 2026.
LinkedIn video specs at a glance
These are the limits for a video you share from your own profile, from LinkedIn's Share videos on LinkedIn and video troubleshooting pages.
| Spec | LinkedIn's rule |
|---|---|
| Length | 3 seconds to 15 minutes (2 seconds minimum from the mobile app) |
| File size | 75 KB to 5 GB |
| Shape (aspect ratio) | Anything from 2.4:1 to 1:2.4 |
| Resolution | 256 × 144 to 4096 × 2304 pixels |
| Frame rate | 10 to 60 frames per second |
| Bit rate | 192 Kbps to 30 Mbps |
| File types | MP4, MOV, AVI, WebM, MKV, WMV and a few more |
LinkedIn lists the file types with a warning: some formats, such as ProRes, may upload but then fail to process. If you're not sure, export an MP4 with H.264 video, the format almost every editor offers by default.
What size should a LinkedIn video be?
There's no single required size. LinkedIn accepts any shape between 2.4:1 (very wide) and 1:2.4 (very tall), so pick the shape that suits where you filmed it. Common sizes that sit inside LinkedIn's range:
| Shape | Example size | Good for |
|---|---|---|
| 16:9 horizontal | 1920 × 1080 | Screen recordings, talks, webinars, anything filmed on a camera |
| 1:1 square | 1080 × 1080 | Clips that need to read well on phone and desktop |
| 4:5 vertical | 1080 × 1350 | Talking-head clips that take up more of the phone screen |
| 9:16 vertical | 1080 × 1920 | Videos you also post as Reels, TikToks or Shorts |
All four are under LinkedIn's 4096 × 2304 maximum. A vertical video you made for another network doesn't need resizing for LinkedIn, which makes LinkedIn one of the easier places to reuse a clip. Our guide to posting the same video on TikTok, Instagram and Shorts covers the rest of that workflow.
Whatever the shape, LinkedIn asks you to keep text, logos and other key details away from the top, bottom and side edges, so the app's buttons and labels don't cover them.
How long can a LinkedIn video be?
It depends on who posts it and how:
| Posted from | Length | File size |
|---|---|---|
| Your profile, on a computer | 3 seconds to 15 minutes | 75 KB to 5 GB |
| Your profile, in the mobile app | 2 seconds to 15 minutes | 75 KB to 5 GB |
| A LinkedIn Page | 3 seconds to 10 minutes | 75 KB to 5 GB |
| An app, through LinkedIn's API | 3 seconds to 30 minutes | 75 KB to 500 MB |
The LinkedIn Pages limits also come with a shorter file type list: LinkedIn says Pages no longer accept AVI, QuickTime or MOV files. The app limits come from LinkedIn's Videos API documentation, which asks for MP4.
Just because LinkedIn allows long videos doesn't mean every post should be long. A short clip that makes one point is easier to watch in a busy feed, and a longer talk or tutorial can still work when the topic needs it.
Thumbnails and captions
On a computer, LinkedIn lets you add two things after you upload a video, before you post:
- Video thumbnail. Upload your own image as the cover.
- Captions. Turn on auto captions, which LinkedIn supports in 10 languages, or upload a caption file. LinkedIn's captions page says the file has to be an SRT.
The mobile app offers auto captions plus trimming, stickers and text, but the steps LinkedIn lists for mobile don't include a custom thumbnail.
Captions are worth the extra minute: they let people follow the video with the sound off.
One more thing LinkedIn points out: you can't post straight into its immersive video feed. LinkedIn fills that feed from videos already shared in the regular feed, based on their quality and relevance.
Posting LinkedIn videos with Unisenda
Unisenda is the scheduler we make. On LinkedIn it posts to personal profiles, not company Pages, and it follows LinkedIn's limits for apps:
- One video per post, 3 seconds to 30 minutes and at least 75 KB. Unisenda takes video uploads up to 500 MB.
- Any shape LinkedIn accepts. Your original file is sent as it is when LinkedIn can take it.
- Phone videos in MOV or HEVC get an H.264 MP4 copy automatically, so you don't have to convert them first. The original stays in your Media library.
- A caption of up to 3,000 characters, with Visibility set to Anyone or Connections only.
To schedule one, click Create post, select your LinkedIn profile and any other accounts, add the video, write your text, and choose the visibility in the LinkedIn tab. Then click Schedule for, pick a date and time, and click Schedule. The full steps are in our guide to scheduling LinkedIn posts.
Unisenda doesn't add a custom thumbnail or a caption file to LinkedIn videos. If you need either, post that video in LinkedIn itself, or put the captions into the video in your editor before you upload it.
To check a file against every network's limits before you post, try the free size checker. You can also try the whole composer in the demo, which uses sample accounts and never publishes anything.
Quick checklist before you post
- Length: between 3 seconds and 15 minutes on your profile, or 10 minutes on a Page.
- Shape: between 2.4:1 and 1:2.4. Vertical, square and horizontal all work.
- File: an MP4 with H.264 video is the safe choice. Avoid ProRes.
- Edges: no text or logos right at the edges.
- Captions: auto captions or an SRT file, or captions in the video itself.
- Text: up to 3,000 characters in the post itself, as LinkedIn's posting help page says. Our character limits guide lists every network side by side.
