Tips for Better LinkedIn Publishing
- Use 1.91:1 when your image supports a link-driven post and needs consistent previews.
- Use square or portrait when you need stronger feed height and better mobile focus.
- Keep logos and CTA copy away from the very top and very bottom of cover images.
It is often faster to create a platform-first master rather than forcing one asset into every ratio. Use this calculator to create intentional variants for feed, story, reel, and thumbnail surfaces.
If you run a cross-platform content calendar, pair this page with related calculators so editors can move from one ratio to the next without rebuilding math manually.
