Best Video Length for LinkedIn in 2026 (Plus Format, Captions and Posting Tips)
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.
LinkedIn video length at a glance
Sweet spot for feed clips: about 30–90 seconds. Avoid very short clips (under about 15 seconds) unless the idea is a single punchy line. LinkedIn allows much longer uploads (up to around 10–15 minutes depending on how you post), but long videos in the feed are best reserved for content people seek out, like a full talk or webinar recording.

Which aspect ratio works best on LinkedIn
Square 1:1 and portrait 4:5 take up more of the feed than landscape and suit desktop and mobile. Vertical 9:16 is supported too. Export 4:5 or 1:1 for feed posts and keep 16:9 for longer talks.
OptimaClip exports every clip in 9:16, 1:1, 4:5 and 16:9, so the LinkedIn version and the TikTok version come from the same cut.
Captions and the post itself
Burn in captions: much LinkedIn viewing happens with sound off. Write a post that adds context in the first two lines (those show before "see more"), upload the video natively, and put any outside link in a comment rather than in the post.
What kind of clips work on LinkedIn
One clear idea per clip: a lesson, a contrarian take, a short case study, a customer story, or a sharp answer from a podcast or webinar. Open with the conclusion and support it with one example. Clips from webinars, panels and founder interviews are a natural fit.
Frequently asked questions
What is the recommended video length for LinkedIn?
About 30–90 seconds for feed clips. Long uploads are allowed but work best for full talks or webinars that people choose to watch.
Should LinkedIn videos be vertical?
Vertical works, but 4:5 or 1:1 often fit the feed better on both desktop and mobile.
Does LinkedIn penalize links in posts?
Posts that send people off LinkedIn tend to get less reach, so upload video natively and add any link in the comments.
