Complete Instagram Image Size Guide
All Instagram image dimensions and aspect ratios
Instagram supports multiple image sizes. Square Posts (1080x1080) are classic Instagram format, perfect for product photos. Portrait Posts (1080x1350 at 4:5 ratio) take up more screen space and get better engagement. Stories and Reels (1080x1920 at 9:16 ratio) fill the entire screen. Profile Pictures (320x320) display as circles, so keep important elements centered.
| Size Type | Dimensions | Aspect Ratio |
|---|---|---|
| Square Post | 1080×1080 | 1:1 |
| Portrait Post | 1080×1350 | 4:5 |
| Story/Reels | 1080×1920 | 9:16 |
| Profile Picture | 320×320 | 1:1 |
Best Practices for Instagram Images
Tips to optimize your Instagram photos
Use portrait orientation (4:5) for feed posts to maximize screen real estate and engagement. Always resize before uploading to prevent Instagram's automatic cropping. For stories, keep text and important elements in the center safe zone (1080x1420). Use high-quality JPG for photos and PNG for graphics with text. Maintain consistent aspect ratios across your feed for a cohesive look.

Frequently Asked Questions
What are the best image sizes for Instagram?
Instagram supports multiple sizes: Square posts (1080x1080), portrait posts (1080x1350), stories/reels (1080x1920), and profile pictures (320x320). Use our Instagram image resizer presets for perfect dimensions every time.
How do I resize an image for Instagram without cropping?
Select "Maintain aspect ratio" and choose "Contain" fit mode. Our tool will add padding (white, black, or custom color) around your image to fit Instagram's dimensions without losing any content.
What's the difference between Instagram post and story size?
Instagram posts use square (1:1) or portrait (4:5) ratios and appear in feeds. Stories use vertical format (9:16) and appear full-screen. Our tool has presets for both - just click the size you need.
Why does Instagram crop my images?
Instagram crops images that don't match required aspect ratios. Use our Instagram image resizer to format images correctly before uploading to prevent unwanted cropping.
What image format is best for Instagram?
Instagram accepts JPG and PNG. JPG is recommended for photos (smaller file size), while PNG is better for graphics with transparency. Our tool lets you choose your output format.
Can I resize old Instagram photos to new dimensions?
Yes! If you have older square posts (1:1) and want to update them to portrait format (4:5) for better engagement, our tool can resize them with smart padding.
