LinkedIn Video Size & Dimensions (2026)

LinkedIn supports three main orientations: 16:9 landscape (e.g., 1920 × 1080), 1:1 square (e.g., 1080 × 1080), and 9:16 portrait (e.g., 1080 × 1920). All three work in the feed, but they look and perform differently.

16:9 landscape is the traditional choice for professional content — webinar replays, product demos, and thought-leadership videos feel authoritative in widescreen. It is also the default export of most screen recorders, so there is no reformatting step for screen-recorded content.

1:1 square often outperforms landscape in the LinkedIn feed because it takes up more vertical space on mobile — users see a larger preview before they scroll past. For software tutorials and short tips, square is worth testing. A 1080 × 1080 square export from a 1920 × 1080 recording requires cropping to the most informative region, which tools like Limelight can automate.

9:16 portrait is increasingly common as LinkedIn has invested in vertical video discovery (the “Videos for You” feed). Use it for content that is designed for mobile-first viewing, like talking-head clips or repurposed Reels and Shorts.

LinkedIn requires H.264 video in an MP4 container. The maximum file size is 5 GB and the maximum duration is 10 minutes. Minimum duration is 3 seconds. LinkedIn recommends a frame rate between 10 and 60 fps — 30 fps is the standard for screen recordings.

For audio, LinkedIn accepts AAC stereo at a minimum of 96 kbps, though 128 kbps or higher is recommended. Videos without audio are allowed but auto-captioning will not trigger — for professional content on LinkedIn, adding narration or background music is generally better for reach.

LinkedIn auto-generates captions for native uploads. The quality varies, and you can replace them with a custom .SRT file after upload. Adding accurate captions significantly improves accessibility and watch time, as most LinkedIn video plays without sound in the feed.

Limelight for Mac exports screen recordings as H.264 MP4 at 1080p in both 16:9 landscape and 9:16 vertical. The 16:9 output is the standard LinkedIn-compatible format — 1920 × 1080, H.264, 30 fps. Upload directly to LinkedIn without any conversion.

For the square 1:1 format, use Limelight’s 9:16 vertical export and then let LinkedIn’s upload editor crop to square, or use any image editor to crop the 1080 × 1920 to 1080 × 1080 before uploading. Center the most important content vertically in the frame so the square crop looks right.

Limelight’s auto-zoom tracks your cursor and zooms into each click, keeping the active region visible even after the frame is cropped to a smaller format. This makes it practical to record once in landscape and repurpose to multiple aspect ratios without re-recording.

Native upload beats links. LinkedIn heavily suppresses posts that include external links (to YouTube, Vimeo, etc.) in the feed. Upload your video directly to LinkedIn — do not paste a link. External link goes in the first comment if you need it.

Hook in the first 3 seconds. LinkedIn auto-plays silently. The first frame should be visually compelling and any text on screen should work without sound. A face or a bold text statement outperforms a title card at the start.

Post during business hours for your target timezone. Unlike TikTok or Instagram, LinkedIn engagement is concentrated in business hours — typically Tuesday through Thursday, 8 am to 12 pm in the audience’s local time. Scheduling posts for peak hours increases the initial velocity that drives organic reach.
