Matching presets
- LinkedIn Post (1200×627) — landscape, matches the link-preview ratio.
- 1:1 Square (1080×1080) — a common choice that holds up on mobile.
- Instagram Post (1080×1350) — 4:5, the tallest ratio LinkedIn allows, so it takes the most room in the feed.
LinkedIn does not publish one ideal pixel size for organic posts, so pick by layout: wide desktop UI suits 1200×627; a phone screen suits 4:5. Open the studio, choose the preset under Export → Canvas Aspect Ratio, and keep text large enough to read on a phone. For X, see the X post image size guide.
Readability on LinkedIn
Most LinkedIn browsing happens on mobile, so a dense desktop screenshot shrinks quickly. Crop to the part of the interface you are talking about, add a short headline with the text tool, and keep the background quiet. Images with a clear single focus tend to be easier to understand at a glance than full-page captures.
