The best vertical size for LinkedIn
9:16 at 1080 × 1920 is the full-screen phone format, the same shape as Shorts, Reels and TikTok. It's the largest 9:16 size LinkedIn lists for ads, and it sits well inside the organic limits. Use it when the video is made to be watched full screen on a phone.
4:5 at 1080 × 1350 is shorter and takes less of the feed. It's also an official LinkedIn ad size. Use it if your audience mostly scrolls the main feed, or if you want one file that works as both a post and an ad.
Whichever you choose, keep faces, captions and on-screen text away from the edges. LinkedIn's full-screen player says that "uploaded videos with a larger aspect ratio may be cropped on the sides as well as at the top and bottom," while wider videos "may be fitted to the screen" (LinkedIn Help). A centred safe area keeps the important parts on screen either way.
How vertical videos get into LinkedIn's video feed
LinkedIn has a full-screen vertical video feed on mobile. You open it by tapping Video in the navigation bar, or by tapping any video in your feed. You can't post into it directly. LinkedIn says "any video you post to LinkedIn may be eligible to appear in the video feed, tab, or carousel based on relevance and performance" (LinkedIn Help).
Two things to know:
- It's mobile only. LinkedIn says the video tab and carousel "aren't currently available on the desktop site."
- Quality affects reach. Visibility depends on "content relevance, quality, and member feedback," and creators whose videos keep getting strong negative feedback may be shown less often to people who don't follow them (LinkedIn Help).
Captions: burn them in
LinkedIn videos "may play automatically without sound" as people scroll (LinkedIn Help). A muted video without captions loses most of its message in the first seconds.
- For ads, LinkedIn accepts captions as a separate SRT file.
- For regular posts, burned-in (open) captions are the safe choice. They show on every device and in every player, whatever the viewer's settings. Our guide to open vs closed captions explains the trade-off, and how to burn subtitles into a video covers the steps.
Keep captions away from the very top and bottom of the frame, since the full-screen player may crop those edges.
How to turn a horizontal video into a vertical LinkedIn video
Most LinkedIn video starts as a webinar, a podcast or a 16:9 talk. To make it vertical without losing the speaker:
- Pick one idea. Cut a single point or story of 30 to 90 seconds. It should make sense to someone who hasn't seen the rest.
- Reframe to 9:16 or 4:5. Crop around the person speaking, not the centre of the frame. If two people talk, stack them or switch between them.
- Add captions and a short on-screen title in the first frame.
- Export an MP4 at 1080 × 1920 or 1080 × 1350, 30 fps.
- Write the post text with the key point first, because longer post text is collapsed in the feed.
Exemplary AI (our product) does steps 1 to 4 for long recordings: it suggests clips, reframes them to vertical around whoever is speaking, and adds animated captions. See the AI clip maker or the video resizer. For a manual method, see how to convert horizontal video to vertical.
What changed on LinkedIn video in 2026
