Link preview (Open Graph) image size
The image shown when a link is shared on Facebook, LinkedIn, Slack, WhatsApp and iMessage should be 1200 by 630 pixels. How to make one that is never cropped badly.

In short: A link preview image, set with the og:image tag, should be 1200 by 630 pixels (1.91:1), a JPG or PNG, and ideally under 1 MB so every app loads it.

Why previews get cropped
Apps crop the preview to their own shape. Some show it square, some wide. Keeping text and faces inside the central square of a 1200 by 630 image means every crop still makes sense.
