Instagram is one of the most visually-driven platforms, and getting your image sizes right is crucial for making your content stand out. Whether you're a business owner, content creator, or casual user, using the correct dimensions ensures your images look crisp and professional across all devices.
Quick Reference
Instagram Post: 1080×1080px (square) or 1080×1350px (portrait). Story: 1080×1920px. Reel Cover: 1080×1920px.
Instagram Post Dimensions
Instagram supports three main aspect ratios for feed posts. Each has its use case and best practices:
| Format | Dimensions | Aspect Ratio | Best For |
|---|---|---|---|
| Square | 1080×1080px | 1:1 | Classic look, product shots |
| Portrait | 1080×1350px | 4:5 | Maximum visibility in feed |
| Landscape | 1080×608px | 1.91:1 | Panoramas, landscapes |
Instagram Story Dimensions
Stories are vertical by design and take up the entire screen on mobile devices:
- Recommended size: 1080×1920 pixels
- Aspect ratio: 9:16
- Minimum width: 600 pixels
- Maximum file size: 30MB for images
Instagram Reel Cover Dimensions
Your Reel cover appears in your profile grid and in the Reels tab:
- Cover size: 1080×1920 pixels (same as Stories)
- Safe zone for text: Keep important content in the center 1080×1420 area
- Profile grid preview: Center 1080×1080 is visible
Pro Tip
Always design for the largest size and let Instagram compress down. Starting with high-resolution images ensures your content looks sharp on all devices, including the latest high-DPI displays.

Common Mistakes to Avoid
- Uploading low-res images: Instagram will compress them further, resulting in blurry posts

- Wrong aspect ratios: Cropped images lose important visual elements
- Over-compressing: Let Instagram handle compression; upload the best quality you have
