Every Threads media size in one cheatsheet
Threads handles feed images, feed video, story and reel reshares through Instagram, and your profile picture — each with its own ideal size. This cheatsheet collects all of them so you can export once, correctly, instead of hunting through scattered guides. A built-in ratio checker confirms your own files match a supported format before you post.
How it works
The tool lists each Threads surface with its recommended pixel dimensions, aspect ratio, accepted formats, and a short note on how the platform displays it. Filter by image or video to narrow the list. When you enter your asset’s width and height, the tool simplifies them to a ratio using the greatest common divisor, so 1080 × 1350 reads as 4:5, letting you confirm a match at a glance.
The numbers
- Feed portrait image: 1080 × 1350 px, 4:5
- Feed square image: 1080 × 1080 px, 1:1
- Feed landscape image: 1080 × 566 px, 1.91:1
- Feed video: 1080 × 1350 px, 4:5
- Story share: 1080 × 1920 px, 9:16
- Reel share: 1080 × 1920 px, 9:16
- Profile picture: 320 × 320 px, 1:1
Tips
Default to 4:5 for posts you want to dominate the feed and 1:1 when consistency across formats matters more than size. Keep text and logos inside the centre safe area on 9:16 story and reel shares, where the Threads and Instagram interface overlays the top and bottom. Always start from a high-resolution master and let Threads downscale, rather than uploading an already-small image that the platform’s compression will degrade further.
