Threads
Last updated: Aug 29, 2025
Threads favors quick, bold visuals. 4:5 and square translate cleanly from Instagram; 9:16 works when repurposing Stories/Reels. Keep designs simple with large type, test in dark mode, and export clean JPG/PNG.
Best Practices
- Favor simple, bold compositions with one focal idea.
- Use 4:5 or square for compatibility; 9:16 when repurposing.
- Export crisp JPEG/PNG; avoid heavy compression.
- Test legibility in dark mode.
- Maintain consistent spacing in carousels.
Pro Tips
- Reuse Instagram templates for speed and consistency.
- Keep on-image text to a minimum; speak in the caption.
- Use a strong first slide to stop the scroll.
- Leverage brand marks/icons sparingly for recognition.
- Preview on small screens to catch tiny text issues.
