💡 For best results, start with an image at least as wide as the target size. Upscaling small images can introduce blur.

Threads post image size: the 2026 spec
This guide covers the official spec, format requirements, and the practical workflow imgsize.cc uses to get it right in your browser.
Why these dimensions
Threads post images render at 1080×1350 on the feed. The 4:5 aspect ratio is recommended — it takes up more vertical real estate in the feed and gets more engagement. Square (1:1) and landscape (16:9) are also accepted.
Crop the central content of your image to the central 80% of the frame. Threads Post Image may crop or overlay UI elements near the edges, so critical content should stay well within the safe zone.
Common mistakes
Text near the edges — covered by Threads UI
Off-center subject — looks unbalanced
Aspect ratio off — letterboxed with white
Frequently asked questions
Does Threads support multi-image posts?
Yes. Up to 10 images per post. Each image keeps its 4:5 ratio.
