Which size to use

Hootsuite recommends 1440 × 1920 (3:4) for Threads feed images. The API takes images from 320 to 1440 pixels wide and scales anything outside that range, so 1440 wide is as sharp as a post gets.

Carousels use the same size. A carousel holds 2 to 20 images and videos, mixed as you like, and it counts as one post toward the API’s limits. For your profile picture, a 640 × 640 square works well.

Threads video limits

The resizer handles still images. For video, these are the limits to plan around.

Tips for Threads images

  • Threads accepts JPEG or PNG up to 8 MB. Download photos as JPG.
  • Images can be as wide as 10:1, so panoramas work, but a 3:4 image fills more of the screen.
  • Mix images and videos in one carousel to tell a short visual story.
