Instagram Carousel Size
Upload every carousel slide at 1080×1350 px (4:5 portrait) for the most feed space, or 1080×1080 px (square). Instagram locks all slides to the ratio of the first one, so pick 4:5 or 1:1 before you start. You can add up to 20 slides.
| Placement | Pixels | Ratio | |
|---|---|---|---|
| Portrait (best) — 4:5 Most feed space; set this on slide 1 |
1080×1350 | 4:5 | |
| Square — 1:1 Safe classic; uniform in grid |
1080×1080 | 1:1 | |
| Landscape — 1.91:1 Allowed but smallest on screen |
1080×566 | 1.91:1 | |
| Max slides Up to 20 images/videos per carousel |

Set the ratio on slide 1
Instagram forces every slide in a carousel to match the aspect ratio of the first slide. Choose 4:5 portrait (1080×1350) for maximum feed real estate, or 1:1 square (1080×1080) for a uniform grid. Mixed ratios get cropped to the first slide's shape.
Keep subjects centered
On the profile grid each carousel shows only its first slide, cropped to 1:1. Design slide 1 to read well as a square thumbnail even if the carousel itself is 4:5.
Up to 20 slides
A carousel holds up to 20 photos or videos. Export each at 1080 px wide; Instagram downscales anything larger to 1080 px.
