what are the dimensions of an instagram post
Instagram feed posts are typically 1080 x 1080 px for square, 1080 x 1350 px for portrait, and 1080 x 566 px for landscape. The most current guides also note that 1080 x 1440 px (3:4) is now supported for feed posts and is often recommended for a taller, more grid-friendly look.
Common Instagram sizes
| Format | Dimensions | Aspect ratio |
|---|---|---|
| Square feed post | 1080 x 1080 px | 1:1 |
| Portrait feed post | 1080 x 1350 px | 4:5 |
| Landscape feed post | 1080 x 566 px | 1.91:1 |
| Tall feed post | 1080 x 1440 px | 3:4 |
| Stories/Reels | 1080 x 1920 px | 9:16 |
Best choice for posts
For most feed posts, 1080 x 1350 px or 1080 x 1440 px works best because they take up more screen space and are less likely to get overlooked in the feed. Square posts still work well if you want a clean, classic grid, but they usually feel smaller on mobile.
Practical tip
If you are designing for Instagram right now, a safe default is 1080 x 1350 px for standard feed content and 1080 x 1920 px for Stories or Reels.
