Aspect ratio
4:5
Use 1080 × 1350 px (4:5 portrait) for Facebook feed images — the tallest format the feed shows without cropping.

Facebook’s feed accepts almost any image, but it displays them very differently. Portrait images up to 4:5 (1080 × 1350 px) get the most screen height on mobile — where the large majority of Facebook time happens — while anything taller is center-cropped down to 4:5. Squares are safe, landscape shrinks, and link previews are their own format entirely (1200 × 630 px pulled from the page’s og:image). Since Meta’s feed treats portrait as the first-class shape across Facebook and Instagram, 4:5 is the right default for designed posts in 2026.
| Variant | Dimensions | Ratio |
|---|---|---|
| Portrait (recommended) | 1080 × 1350 pxTallest ratio the feed displays uncropped; taller uploads are center-cropped to 4:5. | 4:5 |
| Square | 1080 × 1080 px | 1:1 |
| Landscape | 1200 × 630 pxSmallest on screen — best reserved for link previews. | 1.91:1 |
| Link preview (og:image) | 1200 × 630 pxPulled from the linked page’s metadata, not uploaded with the post. | 1.91:1 |
Two crops matter. First, anything taller than 4:5 loses its top and bottom in the feed — if you repurpose a 9:16 Story graphic as a feed post, the headline near the top edge disappears. Second, multi-photo layouts tile images into squares and wide rectangles, so when you post several photos at once, keep each image’s subject dead-center. For single designed posts at 1080 × 1350, a comfortable inner margin of about 10% on all sides keeps text clear of feed rounding and accidental crops in shares.
Most Facebook consumption is mobile, and a 1080 × 1350 image occupies roughly twice the screen of a 1.91:1 landscape one. If you produce one master visual for Facebook and Instagram, 4:5 is the shape that publishes cleanly to both feeds without recropping — one export, two platforms.
When you share a URL, Facebook renders whatever the page declares as its og:image, cropped toward 1.91:1 — you cannot fix it from the composer. If the preview looks wrong, the page’s metadata is the problem. For campaigns where the visual matters, upload the image natively and put the link in the post text or first comment instead.
Meta retired its strict “20% text” rejection rule for ads years ago, but image-heavy text still underperforms in practice — small type is illegible at feed size and reads as an ad even on organic posts. Lead with one short headline in the image and move the detail into the caption, where it is searchable and screen-reader-friendly. A scheduling preview helps catch this: SocialKit shows how each post renders before it publishes to Facebook and the other 10 platforms it supports.
1080 × 1350 px (4:5 portrait) for designed feed posts — it is the tallest shape the feed displays uncropped and takes the most mobile screen space. 1080 × 1080 squares are a safe alternative.
1200 × 630 px (1.91:1), set as the og:image in the linked page’s metadata. Facebook generates the preview from the page itself, so you control it on the website, not in the post composer.
Yes — every upload is re-compressed and resized. Export clean JPGs or PNGs at the target dimensions (1080 px wide for feed images) rather than uploading huge files, and avoid re-saving already-compressed images, which compounds artifacts.
