Instagram Content Best Practices

Use 4:5 portrait (1080×1350) for feed posts - maximum screen real estate on mobile
The new 3:4 (1080×1440) format perfectly matches the updated profile grid preview
Reels under 3 minutes get recommended to non-followers by the algorithm
Carousels support up to 20 slides - use them for educational or storytelling content
Keep Stories content within the center safe zone to avoid UI overlay
Upload Reels at 1080×1920 - Instagram caps playback at 1080p, no 4K support
