LinkedIn Video and Image Sizes 2026

This is one of the most common questions about LinkedIn video format: should you upload the video directly to LinkedIn, or post a YouTube link in your post? The answer matters because the two approaches get very different distribution.

Native video consistently outperforms YouTube links on LinkedIn. LinkedIn's algorithm reduces the reach of posts that send users away from the platform. A YouTube link in a post gets roughly 50-70% less distribution than the same content uploaded natively. LinkedIn has confirmed this directly in their guidance for creators.

When to use native video: Any content you want maximum people to see. Thought leadership, company updates, product launches, educational content. Follow the LinkedIn video format requirements: H.264, 1:1 or 4:5 aspect ratio, captions uploaded as SRT.

When to use a YouTube link: When your goal is YouTube watch time and subscriber growth rather than LinkedIn reach. Post the YouTube URL in the first comment (not the post text) to slightly reduce the reach penalty. This is common for long-form tutorials where YouTube monetization and search traffic are the primary goals.

The practical approach for most creators: upload short-form content (under 3 minutes) natively to LinkedIn following the LinkedIn video format requirements, and link to longer content on YouTube from the comments. Both platforms benefit.

LinkedIn's audience context is fundamentally different from consumer platforms — and this affects which aspect ratios and formats perform best, beyond just meeting the technical LinkedIn video format requirements.

Desktop-first browsing: LinkedIn is the only major platform where a significant portion of users (roughly 40-50%) are on desktop. TikTok and Instagram are almost entirely mobile. This means 9:16 vertical video — which fills a mobile screen — performs less predictably on LinkedIn. On a 1920x1080 desktop monitor, a 9:16 video plays in a small centered window. 1:1 square gives you 6x more screen real estate on desktop.

Silent viewing: As noted, 85% of LinkedIn video plays muted. This is far higher than TikTok (40% muted) or YouTube. Every LinkedIn video needs visual captions or text overlays — the content has to communicate without audio.

Professional context: LinkedIn users scroll between meetings, in offices, on public transport. Short, punchy videos (60-90 seconds) outperform long tutorials. The 15-minute maximum is technically supported but rarely the right choice for organic content.

File size: LinkedIn's 5GB video limit is more generous than TikTok (287MB) or Instagram (1GB). This allows higher-quality uploads without file size management, especially useful for polished company videos where visual quality matters.

LinkedIn research shows 85% of LinkedIn video is watched without sound. Unlike TikTok or Instagram Reels, LinkedIn is often browsed in a workplace context — open offices, meetings, commutes. If your video only delivers value through audio, you lose 85% of your potential audience.

LinkedIn supports SRT caption file uploads directly. Add captions to every video. Beyond accessibility, captions increase watch time because viewers who can't turn on audio can still follow along and choose to engage. LinkedIn's official video specs help article covers captions and supported formats in detail.
