Use a 1.91:1 image of at least 1200 x 630 px for og:image. That is Facebook's recommendation and clears LinkedIn's minimum of 1200 x 627 px. Keep the file under 5 MB so it works on LinkedIn too; Facebook allows up to 8 MB and shows anything below 600 x 315 px much smaller.
| Placement | Size | Aspect ratio | Max file size | Copy or link |
|---|---|---|---|---|
| og:image for Facebook link shares | 1200 x 630 px | 1.91:1 | 8 MB | |
| Facebook large link preview (minimum) | 600 x 315 px | Not published | Not published | |
| og:image for LinkedIn shares | min 1200 x 627 px | 1.91:1 | 5 MB |
Every row links to the full spec below, with its source. "Not published" means Open Graph and link previews doesn't state it, so we don't either. Download all 4 specs as CSV.

Facebook recommends at least 1200 x 630 px (1200 by 630 pixels), close to 1.91:1, under 8 MB. LinkedIn requires at least 1200 x 627 px at 1.91:1, up to 5 MB, so 1200 x 630 px works for both.
Facebook accepts images down to 200 x 200 px, but below 600 x 315 px link posts show a much smaller image. LinkedIn's minimum is 1200 x 627 px.
1.91:1. Facebook says images close to 1.91:1 display in full without cropping, and LinkedIn recommends the same ratio.
8 MB for Facebook and 5 MB for LinkedIn. Stay under 5 MB if the page will be shared on both.
X's current developer docs no longer publish a card image size; the old summary card pages now redirect. A 1.91:1 image at 1200 x 630 px meets Facebook's recommendation and LinkedIn's minimum.
Neither publishes an image size in official documentation we could check. A 1.91:1 image at 1200 x 630 px meets every published spec on this page.
