Threads Image Sizes
Threads uses the same upload rules as Instagram: 1080px wide, portrait 4:5 gets the most space. There's no cover photo — just posts and a circular avatar. Every placement below, with copy buttons.

Post portrait: 1080×1350
Threads accepts square, landscape and portrait images, all 1080px wide. Portrait 4:5 (1080×1350) takes the most room as people scroll, so it earns the most attention. There is no header or cover image on Threads.
Same pipeline as Instagram
Because Threads and Instagram share infrastructure, the safe bet is to design once at 1080×1350 and reuse it on both. The profile photo is a circular 320×320.
FAQ
What is the best image size for Threads?
1080×1350 pixels (4:5 portrait). It fills the most of the feed. Square 1080×1080 also works.
Does Threads have a cover or header photo?
No. Threads only has a circular profile picture (320×320) and post images — there is no banner.
Can I reuse Instagram images on Threads?
Yes. They share the same 1080px-wide rules, so a 1080×1350 image works on both.
