Instagram post size
Prepare a photo for the Instagram feed with a choice of four shapes. Start with a 1080 × 1350 portrait, switch to square or landscape, or try a taller 3:4 composition. Your picture stays on your device throughout editing.

How to use it
- Choose the original image from your device or drag it into the upload area.
- Select portrait, square, landscape or the taller 3:4 preset.
- Use Fill to crop and drag the subject into place, or Fit to retain the full photo.
- Download the JPG, then check its crop in the Instagram composer before posting.
Choose the shape for the picture
A portrait frame gives you room above and below a subject. A square works well for a centered product or an existing square graphic. Landscape is useful when the relationship between people or objects matters more than a close crop. Select a size before adjusting the position, because each shape changes which part of the source photograph fits.
What the pixel numbers mean
Every preset here exports a file 1080 pixels wide. The height changes with the selected shape: 1350 for 4:5, 1080 for square, 566 for landscape and 1440 for 3:4. These are the dimensions of the downloaded picture, not a prediction of its size on every phone. Instagram can display smaller versions and process the file again.
Keep a whole photo or fill the frame
Fill and crop enlarges the picture until there are no empty edges, then lets you move the crop. Fit with padding preserves the entire photograph inside the chosen shape. A blurred background is useful for a horizontal photo in a portrait post. A solid background works better when the image already has a simple studio backdrop.
Prepare for the profile grid
The image in the feed and its thumbnail on your profile are different views. Keep your face, product name or main subject near the middle rather than relying on details at a corner. A tall post can still look different in a grid. Review the profile preview in Instagram before publishing, particularly when a series is designed to align across several tiles.
Export from the original
Start with the camera file or the original design export when you have it. A screenshot of a previously published post already contains scaling and compression. Increasing its dimensions cannot recover the missing detail. The resizer warns when it enlarges a small picture; compare the downloaded image at full size before deciding whether the softer result is acceptable.
Finish inside Instagram
Save the JPG and select that file in your post composer. Inspect the selected crop before adding your caption. If a scheduling service offers fewer shapes than the Instagram app, choose one it supports or upload directly through the app. Add a written description of important visual information so the meaning of a post does not depend entirely on reading text inside the image.
