What's the best length for a LinkedIn video clip in 2026?

The best length for a LinkedIn video clip in 2026 is roughly 30 to 90 seconds — longer than the TikTok sweet spot — because LinkedIn's audience is watching with professional intent and will give a clear, useful point more time to land before swiping.

The floor matters too. Clips under about 15 seconds tend to underperform on LinkedIn; they read as filler in a feed where users expect a complete thought. A clip that makes one argument with one example, in 45 seconds, is close to ideal.

Native upload is non-negotiable. LinkedIn suppresses reach on posts that link out to YouTube or TikTok, so upload the video file directly and put any link in the first comment.

Captions are essential and should be burned in. A large share of LinkedIn video is watched muted during the workday, and LinkedIn's own auto-captions are less reliable than a clean burned-in track.

Vertical 9:16 works, but 1:1 and 4:5 often perform better in the LinkedIn feed because they occupy more vertical space without triggering the full-screen player, keeping the viewer in-feed where the like and comment buttons are.

Lead with the claim, not the credentials. LinkedIn viewers scroll past 'Here's what I learned in 10 years of…' — a clip that opens on the actual conclusion holds them.

In OptimaClip, the 4:5 and 1:1 exports plus burned-in captions cover what LinkedIn specifically needs, and the moment-detection tends to surface the single-argument segments that fit the platform's longer, slower feed.
