The problem

Threads crops square and landscape images in the feed. The 4:5 portrait format fills more of the screen but your photos aren't the right shape.

The fix

Upload your image. Select Threads Post (1080×1350). Drag to reposition. Download the perfectly framed result.

How it works

Threads Post: 1080×1350 (4:5)
Fills more of the feed than square
Crop mode with live preview
Same format as Instagram Portrait

FAQ

What size should a Threads image be?
Threads supports multiple aspect ratios but the 4:5 portrait (1080×1350) fills the most screen space in the feed and is widely recommended for maximum visibility.
What aspect ratio does Threads use?
Threads supports 1:1 (square), 4:5 (portrait), and 1.91:1 (landscape). Portrait 4:5 at 1080×1350 gives the largest feed presence on mobile.
Is Threads the same image size as Instagram?
The formats overlap. Threads uses the same 4:5 portrait (1080×1350) and 1:1 square (1080×1080) as Instagram. Threads does not support Stories or Reels.
Can I post a landscape image on Threads?
Yes. Threads supports landscape images at up to 1.91:1 ratio. However, portrait format (4:5) takes up significantly more feed space, which typically leads to more engagement.
