Threads Post Image Resizer

What matters

Threads Post Image dimensions at a glance

Threads post images display well at 1080×1080 square. The platform supports multiple aspect ratios but square is the most predictable across all feed contexts.

Threads is primarily text-focused, so attached images need to be immediately impactful to complement the post rather than feeling like an afterthought.

Odd ratios may be cropped or displayed with uneven padding in the feed, making the post look less polished than text-only alternatives.

Best practices

Use the crop intentionally

• Match Instagram post dimensions for cross-posting consistency.
• Keep images simple and punchy — Threads is a fast-scrolling text feed.
• Square is the safest bet until the platform's image display stabilizes.
