Threads
Last updated:
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.

FAQ
What's the best post size on Threads?
4:5 (1080×1350) is the sweet spot — it translates cleanly from Instagram and fills maximum feed height. Square (1:1) also works but gains less vertical space.
How much on-image text is okay on Threads?
Minimal. Threads reads more like Twitter/X than Instagram, so let the post copy do the heavy lifting and keep images clean.
Do I need to worry about dark mode on Threads?
Yes. Threads defaults to dark mode for many users. Always test contrast and avoid low-contrast overlays or thin lines that disappear on black.
Can I cross-post between Threads and Instagram?
Yes, and it's encouraged — 4:5 (1080×1350) works for both. Threads also supports video but with stricter length limits than Reels.
What video specs does Threads support?
Up to 5 minutes at launch, expanding over time. Use 1080×1920 (9:16) for vertical or 1080×1350 (4:5) to match Instagram feed video.
How many images can I attach to a Threads post?
Up to 10 images or videos per post, which render as a swipeable carousel in the feed.
