Threads Post Image size 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.
Why 1080×1080 matters
Threads is primarily text-focused, so attached images need to be immediately impactful to complement the post rather than feeling like an afterthought.
What happens when the size is wrong
Odd ratios may be cropped or displayed with uneven padding in the feed, making the post look less polished than text-only alternatives.

- Match Instagram post dimensions for cross-posting consistency.
