LinkedIn Video Length Limit 2026 (15 Min)

LinkedIn's video length limit for a standard organic post is 15 minutes, and per LinkedIn's own help page that ceiling now applies regardless of device. The only device difference left is the minimum: at least 3 seconds uploading from desktop, 2 seconds from the mobile app. Video ads run through Campaign Manager get the most room at up to 30 minutes. You will still see a 10-minute mobile cap quoted around the web; that number is stale.

Native video: 15 minutes on any device

Uploading a video directly to your LinkedIn feed allows videos up to 15 minutes long whether you post from a desktop browser or the mobile app. This is the ceiling for a standard organic post, useful for longer thought leadership pieces, panel clips, or webinar recordings you want to host natively rather than link out to. The device split that used to exist here now applies only to minimum length: LinkedIn requires at least 3 seconds on desktop and 2 seconds on mobile.

Video ads: up to 30 minutes, but shorter performs better

Paid video ads through Campaign Manager technically accept durations from 3 seconds up to 30 minutes. In practice, LinkedIn's own guidance and most advertiser data point to under 30 seconds for awareness campaigns and generally under a minute for the best engagement, so the 30 minute ceiling exists mostly for edge cases like full webinar replays run as ads, not as a target length.

Quick reference

Upload path	Length
Native video, any device	Up to 15 minutes
Minimum, desktop	3 seconds
Minimum, mobile app	2 seconds
Video ads	Up to 30 minutes

Why the device gap closed

LinkedIn used to cap mobile uploads at 10 minutes while allowing 15 from desktop, a split that made sense years ago when mobile video processing was more limited. That gap has closed: per LinkedIn's current help documentation, the 15 minute ceiling now applies regardless of which device you upload from, with only the minimum length still differing by a couple of seconds. If you have seen the older 10 minute mobile figure recently, it is out of date, a common side effect of how slowly some platform spec guides get updated after LinkedIn quietly changes a limit.

Picking a length that actually performs

Regardless of the technical ceiling, videos between 15 and 60 seconds produce the strongest engagement for most B2B content on LinkedIn, since attention drops off quickly in a professional feed. Save the longer allowances for genuinely long-form content like recorded talks, and check the accompanying LinkedIn video file size limit before uploading.
