Why this size

Instagram sizes at a glance

Square posts show fully in the feed and the profile grid. Uploading the exact size means Instagram does not crop or re-compress your image in ways you did not choose.

The tool scales once, straight to 1080 x 1080, from your original pixels, so the result stays sharp. Start from a photo at least as large as 1080 x 1080: enlarging a small image cannot add detail. For a small old photo, the AI upscaler can redraw it larger first.

Use	Size
Square post	1080 x 1080 px (1:1)
Portrait post	1080 x 1350 px (4:5)
Landscape post	1080 x 566 px (1.91:1)
Story or Reel	1080 x 1920 px (9:16)

Tips

Tips that make a difference

Start from the original photo

Use the photo from your camera or gallery, not a screenshot or a copy forwarded in a chat. Scaling down to 1080 x 1080 keeps it sharp; scaling up a small image makes it soft.

Uploads get compressed again

Most platforms, Instagram included, re-compress images after upload. A JPG at the exact size gives them the least to change, so colors and edges stay closer to your original.
