What Instagram Reels doesn't publish
Creators ask about these, but there's no official number. We leave them out rather than guess.
- Maximum file size for reels uploaded in the app
- Minimum length for reels recorded in the app
- A safe zone for organic reels separate from Meta's Reels ad guidance
Exporting for Instagram Reels
Export 9:16
1080x1920 fits the 9:16 ratio Meta recommends and stays under the 1920 px width cap.
Keep it under 3 minutes to grow
Reels can run to 20 minutes, but only reels up to 3 minutes are recommended to people who don't follow you.
Respect the safe zone
Leave the top 14%, bottom 35% and 6% on each side free of captions and key text. On a 1080x1920 frame that's roughly the top 270 px and bottom 670 px.
Encode conservatively
H.264 or HEVC in an MP4, 23–60 fps, video bitrate at or under 25 Mbps, AAC audio at 48 kHz or less.
Mimic exports vertical 9:16 video with captions and titles kept inside the apps' safe zones and off the speaker's face.
