Resize to 1080x10801:1
1080x1080 px, 1:1. 1080x1080, 1:1. The grid thumbnail and the classic feed post.
Trims the edges that do not fit, so nothing is squashed.
Faces near the top of a tall photo? Pick Top. Check the preview after it runs.

Instagram post size: 1080 wide, square, portrait or landscape
Instagram normalises every feed image to 1080 pixels wide and allows three shapes: a 1080x1080 square, a 1080x1350 portrait at 4:5, and a 1080x566 landscape at 1.91:1. Stories and Reels are a separate 9:16 frame at 1080x1920, and the profile picture is stored at 320x320. Upload anything else and the app either crops it to the nearest allowed shape or scales it, then compresses the result.
The reason to resize before posting is that compression and resizing happen together on Instagram's side. An image that arrives already at 1080 wide only gets the compression pass. The tool above produces the exact pixels for whichever shape you pick, lets you decide which part of a photo survives a crop, and can pad instead of cropping when you do not want to lose the edges.
| Use | Pixels | Ratio | Notes |
|---|---|---|---|
| Square | 1080x1080 | 1:1 | 1080x1080, 1:1. The grid thumbnail and the classic feed post. |
| Portrait | 1080x1350 | 4:5 | 1080x1350, 4:5. The tallest a feed post can be, so it takes the most screen. |
| Landscape | 1080x566 | 1.91:1 | 1080x566, 1.91:1. For wide photos you do not want cropped to a square. |
| Story / Reel | 1080x1920 | 9:16 | 1080x1920, 9:16. Stories, Reels covers and full-screen vertical posts. |
| Profile photo | 320x320 | 1:1 | 320x320. Instagram shows the DP at 110x110 but stores 320, so upload this. |
How to resize a photo for Instagram
- Drop one photo or a whole carousel's worth above (up to 20). Every file in the batch gets the same size and crop settings, so a carousel comes out uniform.
- Pick the shape. Portrait fills the most of the feed and matches the current profile grid; Square is safest for a carousel mixed with older posts; Landscape suits wide scenes you refuse to crop.
- Phone photos are 4:3, so Portrait and Square both crop a little. Use Keep this part to choose Top for standing portraits or Centre for most other shots, and check the preview row.
- Download, or Download ZIP for a batch, then post from the app. The crop screen will show the image already filling the frame.
Carousels, the 2025 grid, and the no-crop option
A carousel locks every slide to the shape of the first one, which is where mismatched batches go wrong: a portrait first slide forces a crop on a landscape third slide inside the app. Resizing the whole set here at one size avoids that entirely, and the ZIP keeps the filenames in order.
The profile grid now shows portrait tiles rather than squares, so a square post is cropped in the grid even though it opens at full size. If you want the grid and the post to look the same, shoot or crop at 4:5. And when a photo simply cannot be cropped, Pad to fit places the whole image inside the chosen shape with white or black bars, which Instagram treats as part of the picture and never trims. For a small source that had to be enlarged, the AI image upscaler will give you a cleaner 1080 than plain scaling can.
Frequently asked questions
- What size should an Instagram post be?
- 1080 pixels wide, at one of three heights: 1080 for a square (1:1), 1350 for portrait (4:5) or 566 for landscape (1.91:1). Instagram scales everything to 1080 wide, so uploading wider only means more compression. Portrait 1080x1350 takes the most screen in the feed, which is why most creators default to it now.
- Why does Instagram crop my photo?
- Because the photo's shape is outside the allowed range. Anything taller than 4:5 is cropped at the top and bottom, anything wider than 1.91:1 at the sides. Resize to one of the exact sizes above first and the in-app crop screen has nothing to take; if you want the whole photo with no trim, use Pad to fit and the bars become part of the image.
- Does the profile grid still show squares?
- Not since 2025. Instagram changed the profile grid to taller rectangles, so a square post is shown cropped in the grid preview and a 1080x1350 portrait fits it naturally. The full image still opens at its real shape; only the grid tile changed. If the grid look matters to you, post portrait.
- What size is an Instagram profile picture?
- Instagram displays it at 110x110 on a phone but stores a 320x320 version, so 320x320 is the file to upload. It is shown as a circle, so keep the face in the middle; the Centre crop position does that for a normal portrait.
- Will the quality drop after upload?
- Instagram re-encodes every upload, and it compresses hardest when it also has to resize. Uploading an image that is already exactly 1080 wide removes the resize step, which is the single biggest thing you can do for quality. Use JPEG at the quality this tool picks; PNG gets converted anyway.
- Is my photo uploaded to this site?
- No. Nothing is uploaded: the crop and the resize run in your browser, and the file never leaves your phone or computer. No account, no watermark, no limit on how many you resize.
