Instagram has 6 different image sizes depending on where the image appears. Using the wrong size means your photo gets cropped, stretched, or displayed with black bars. Here are the exact dimensions you need.
Instagram Image Sizes (2026)
| Placement | Dimensions (px) | Aspect Ratio | Max File Size |
|---|---|---|---|
| Square feed post | 1080 x 1080 | 1:1 | 30 MB |
| Portrait feed post | 1080 x 1350 | 4:5 | 30 MB |
| Landscape feed post | 1080 x 566 | 1.91:1 | 30 MB |
| Story / Reel | 1080 x 1920 | 9:16 | 30 MB |
| Profile picture | 320 x 320 | 1:1 | N/A |
| Carousel | 1080 x 1080 or 1080 x 1350 | 1:1 or 4:5 | 30 MB per image |
Which Size Gets the Most Engagement?
Portrait (4:5) posts take up the most screen real estate in the feed, which means more time in view, which means more engagement. Data from multiple studies shows 4:5 posts get 10-15% more engagement than square posts. Use 1080x1350 as your default unless you have a specific reason for square or landscape.
Common Mistakes
- Uploading at original camera resolution. A 4000x3000 photo gets compressed by Instagram. Upload at 1080px wide for the best quality-to-compression ratio.
- Using landscape for feed posts. Landscape images are tiny in the feed. They get scrolled past faster.
- Ignoring the safe zone for Stories. The top 250px and bottom 250px of Stories are covered by the username and reply bar. Keep important content in the middle 1420px.
