Threads image & video sizes (Updated 2026)
Threads feed stills keep their original aspect unless you crop them. Optional composer crops match Meta ratios (4:5, 1:1, 1.91:1). Stories follow the familiar 9:16 Meta canvas.

Best practices
- SocialRobot keeps feed stills full-frame and scales the long edge toward 1440px unless you crop.
- Optional crops: 4:5 (1080×1350), 1:1, or 1.91:1.
- Use 1080×1920 for Stories.
- Keep stills under 8 MB.
- Carousels support 2–20 items.
Common mistakes
- Oversized PNGs that fail the 8 MB cap.
- Single-image “carousels” under the 2-item minimum.
- Video longer than five minutes.
