Using the correct image dimensions prevents automatic cropping and compression by the platform.
Correct dimensions
| Format | Dimensions | Aspect Ratio | Notes |
|---|---|---|---|
| Square post | 1080 × 1080 px | 1:1 | Default and most recommended |
| Portrait post | 1080 × 1350 px | 4:5 | Gets more feed space — highest engagement |
| Landscape post | 1080 × 566 px | 1.91:1 | Wide format, less feed space |
| Story / Reel | 1080 × 1920 px | 9:16 | Full screen vertical |
| Profile photo | 320 × 320 px | 1:1 | Displayed as circle — keep subject centered |
Instagram compresses images that don't match these dimensions. Use the correct size to get the best quality.
Tips
- Always use the highest resolution original — you can always resize down, never up without quality loss

FAQs
What happens if I use the wrong size?
The platform auto-crops or compresses your image, often losing quality or cutting off important content.
Should I resize before or after editing?
Edit first, then resize to the target dimensions as the last step.
What format is best?
JPG at 85-90% quality is best for photos. PNG is best for graphics, logos and images with text.
