Turn a tweet into a LinkedIn image

LinkedIn renders feed images at roughly 1.91:1, the same landscape shape as a link preview card. A square or vertical tweet screenshot gets letterboxed or cropped, which is why reposted tweets so often look sloppy there.

Paste a link above to see the preview here.

This page starts at 1200 by 627 on a plain light background, because LinkedIn's own interface is light and a black card fights it. Metrics stay visible here — on LinkedIn the engagement numbers are often the reason the tweet is worth sharing.

Questions

What image size works best on LinkedIn?
1200 by 627 pixels. LinkedIn crops taller images in the feed and shows them at that landscape ratio anyway.
Should the card be light or dark for LinkedIn?
Light. LinkedIn's feed is light by default, so a light card looks native rather than pasted in.
Can I share a tweet on LinkedIn without an image?
You can paste the link, but LinkedIn suppresses reach on posts with external links. An image keeps the engagement on the post.
