Instagram image & video sizes (Updated 2026)
Instagram enforces a hard aspect range for feed images and re-encodes uploads. Starting at 1080px wide in a supported ratio keeps posts sharp and fully visible.

Best practices
- Use 4:5 (1080×1350) for feed photos to take more vertical space.
- Export Stories and Reels at 9:16 so they fill the screen.
- SocialRobot converts stills to JPEG and fits the legal aspect range at publish.
Common mistakes
- Uploading ultra-tall or ultra-wide images that fall outside 4:5–1.91:1.
- Placing key text under Story UI chrome at the top or bottom.
- Sending WebP or oversized PNGs that get rejected or re-compressed badly.
