LinkedIn feed video size
LinkedIn is mostly consumed on mobile despite the desk-job assumption, so vertical-leaning ratios take more screen. 4:5 is the tallest the feed renders in full.

What to watch out for on LinkedIn
- Most of the audience watches muted in a work context, so captions are not optional.
- The first frame doubles as the thumbnail unless you upload one.
- Landscape still works for recorded talks and demos where the wide frame carries information.
