Instagram sizes in 2026
Portrait 1080 x 1350 (4:5), square 1080 x 1080 (1:1), landscape 1080 x 566. The profile grid now previews posts as 3:4, so keep faces near the centre.
See it before you post
The preview shows your photo inside a mock of Instagram for feed, profile grid, including the areas that get covered or cropped, so you can fix the framing before you upload.
Tip
Use Crop to fill and drag the photo in the preview so faces sit in the middle, or Whole photo to keep everything with a soft blurred background around it.
Resize a whole batch
Drop many photos at once. Each one keeps its own crop position, and you can download them all as a ZIP. Everything runs in your browser, so nothing is uploaded.
