Instagram Image Sizes
| Type | Size (px) | Ratio |
|---|---|---|
| Square Post | 1080 × 1080 | 1:1 |
| Portrait Post | 1080 × 1350 | 4:5 |
| Landscape Post | 1080 × 566 | 1.91:1 |
| Stories / Reels | 1080 × 1920 | 9:16 |
| Profile Picture | 320 × 320 | 1:1 |
Instagram supports images between 320px and 1080px wide. Images smaller than 320px will be enlarged (causing blur), and images larger than 1080px will be compressed. For the best quality, always upload at exactly 1080px wide.
Facebook Image Sizes
| Type | Size (px) | Ratio |
|---|---|---|
| Shared Image | 1200 × 630 | 1.91:1 |
| Cover Photo | 820 × 312 | 2.63:1 |
| Profile Picture | 170 × 170 | 1:1 |
| Event Cover | 1200 × 628 | 1.91:1 |
| Stories | 1080 × 1920 | 9:16 |
Facebook compresses images during upload. To minimize quality loss, upload PNG files for graphics with text, and JPG files at maximum quality for photographs. Keep file sizes under 100KB for the sharpest results after Facebook's compression.

Tips for Resizing Images
- Always start with the highest resolution — Downscaling preserves quality; upscaling creates blur.
- Use the correct aspect ratio — Mismatched ratios cause awkward cropping on social platforms.
- Optimize file size — After resizing, compress your image to reduce load times without visible quality loss.
- Test on mobile — Most social media is consumed on mobile devices. Preview your images on a phone screen.
- Use PNG for text-heavy graphics — PNG preserves sharp text edges better than JPG compression.
