Instagram landscape size: 1080 × 566 px at 1.91:1
1.91:1 is the widest a feed post gets; anything wider has its sides cropped. No Meta document states that width, so the table says where each figure came from.

The numbers, and where each one came from
| Spec | Value | Where this comes from |
|---|---|---|
| Widest accepted ratio | 1.91:1The same ratio Meta's link previews use across its products. Instagram publishes no current page stating it for feed posts. | UnverifiedshotMod |
| Pixel size at 1080 wide | 1080 × 566 px1080 ÷ 1.91 = 565.4, rounded up to an even number of rows so encoders do not complain. | DerivedshotMod |
| Compared with 16:9 | 1.91 vs 1.78A 16:9 export is very slightly taller than the limit, so it is accepted intact rather than cropped. | DerivedshotMod |
| What happens if you go wider | the sides are trimmedA panorama is cropped, not letterboxed — which is why an ultra-wide shot loses its ends. | UnverifiedshotMod |

What this actually means
Landscape is the least used and most misunderstood feed shape. Instagram's ceiling is 1.91:1, an odd ratio that comes from the link-preview card Meta uses across its products rather than from anything photographic. It is not 16:9, it is not 2:1, and it is not the shape any camera produces — which is why almost every wide photo needs a deliberate decision before it goes up.
It is also the shape that costs you the most attention. A landscape post occupies about a third of the vertical space a 4:5 post does on the same screen, so it scrolls past faster and gives a viewer less time to stop. Choosing it should be a compositional decision — a real panorama, a wide interior, a diagram that only works wide — not a default inherited from your camera roll.
What goes wrong
Going wider than 1.91:1 does not letterbox, it crops. A 21:9 cinematic still or a stitched panorama loses both ends, and since the ends are usually where a panorama earns its keep, the result reads as a badly framed ordinary photo. If your image is wider than the ceiling, decide yourself which part survives, or split it across a carousel where each slide keeps its own detail.
The profile grid gets you here as well, only in reverse. A very wide post becomes a centre-cropped square thumbnail on your profile, which throws away far more of a landscape frame than it does of a portrait one. A wide shot that depends on its full width will look, on your own profile, like a random square cut out of the middle — worth checking before you commit the post.
How to do it here, in three steps
- 1.91:1 · 1080 × 566 is already selected, and it is the widest the feed accepts.
- Add your wide photo and decide, before you export, which ends you are willing to lose.
- Use Bars to keep the whole frame, or Crop to fill it edge to edge, then export.
Questions, answered
What is the landscape size for an Instagram post?
1080 × 566 pixels, which is 1.91:1 — the widest ratio a feed post can use. Instagram does not publish this on a current page, so treat it as long-standing convention rather than documented specification.
Can I post a 16:9 photo on Instagram?
Yes. 16:9 is 1.78:1, slightly taller than the 1.91:1 ceiling, so it is accepted as-is rather than cropped. It simply sits a few pixels short of the widest shape available to you.
What happens to a panorama on Instagram?
Anything wider than 1.91:1 has its sides trimmed rather than letterboxed, so the ends of a panorama are removed. Splitting it across carousel slides keeps the whole scene at full detail.
