1200 x 630 pixels is the standard Open Graph image size — the image that renders when a link is shared on Facebook, LinkedIn, Slack, iMessage, and most other platforms that read og:image tags. Its roughly 1.91:1 ratio matches the link preview card, so the image fills the card without awkward cropping.

When someone shares a page, the preview image comes from the page's og:image tag — and 1200 x 630 is the size sharing guidelines recommend so the card renders sharp at full width.A page without a correctly sized preview image gets a cropped fragment, a tiny thumbnail, or no image at all — this size is what prevents that.
Preview cards are wide and short. An image already at ~1.91:1 fills the card exactly; a square or tall image gets its top and bottom cut off by the platform’s automatic crop.Compose for the wide frame: subject centred, headline text large, nothing important near the top or bottom edges.
Facebook, LinkedIn, Slack, Discord, iMessage, and most chat apps all build their preview cards from the same og:image, so one 1200 x 630 export covers all of them.X (Twitter) reads its own card tags but handles a 1.91:1 summary image cleanly too — the same export works there for large link cards.
