Ever upload a photo to Instagram, and try as you might to pinch it into the perfect position, you still can’t get it to fit into the box the way you want? Yeah, me too. The only way to prevent this is to ensure your content fits Instagram’s preferred post dimensions.
Of course, the app has changed the aspect ratio for reels and feed posts over time to…keep things interesting, I guess?
Not to worry, though; this Instagram post size guide will tell you the exact dimensions your content should be to avoid unexpected cropping, as well as how to make it work when you’ve got content that doesn’t align with the needed dimensions.
Why Instagram Crops Photos
Instagram crops photos because the app is designed around specific aspect ratios and display formats. If your image doesn’t fit those dimensions, Instagram will automatically trim, zoom, or reposition your content to fit within the app.
Unfortunately, Instagram doesn’t display content the same way everywhere. A photo or reel cover that looks perfect in the feed might appear cropped on your profile grid or when shared as a preview.
How to stop the crop
The best way to prevent Instagram from cropping your photos is to upload images with the recommended dimensions and aspect ratios (more details below). If your content already fits the platform’s preferred sizes, unwanted zoom or trim is much less likely.
Here are our best practices:
Use Instagram-friendly dimensions
Before uploading, resize your images to match Instagram’s recommended sizes:
- Portrait posts: 1080 x 1350 pixels (4:5)
- Square posts: 1080 x 1080 pixels (1:1)
- Landscape posts: 1080 x 566 pixels (1.91:1)
- Stories and Reels: 1080 x 1920 pixels (9:16)
Tap the expand icon while uploading
When uploading a feed post, Instagram typically defaults to a square or portrait preview. Tap the expand/full-size icon in the lower-left corner of the image to restore the original aspect ratio.
Keep important elements centered
Profile grids, Reel previews, and Explore placements may crop your content differently than the main feed. To avoid losing anything important, keep your text, face (if you’re in it), graphics, and any other design elements near the center of the image.
Add borders or background padding
If your image doesn’t fit Instagram’s dimensions, you can add white space or a colored background around it to avoid Instagram cropping it automatically. Tools like Canva or Adobe Express make this easy.
Preview before posting
A quick preview can save you from posting an accidentally cropped image or cut-off text. Always check how your content looks in:
- the feed
- your profile grid
- Reel previews
- carousel slides

Reels
- Aspect ratio: 9:16
- Dimensions: 1080 x 1920 pixels
Reel covers have the same aspect ratio and dimensions as reels themselves. Use the preview function when you’re choosing your reel cover to make sure it doesn’t crop weird on your grid. The best practice is to keep text and stickers within the central 4:5 area (1080 x 1440 pixels).

Stories
- Aspect ratio: 9:16
- Dimensions: 1080 x 1920 pixels
Avoid placing text or interactive stickers within the top or bottom 250 pixels, where the profile icons and reply bars live.

Feed posts
With feed posts, you can use portrait, square, or landscape photos.
Portrait (recommended)
- Aspect ratio: 4:5
- Dimensions: 1080 x 1350 pixels
Square
- Aspect ratio: 1:1
- Dimensions: 1080 x 1080 pixels
Landscape
- Aspect ratio: 1.91:1
- Dimensions: 1080 x 566 pixels
Carousels
With carousels, you can go with portrait or square, but you can’t do both at once. All slides in a carousel must use the same aspect ratio chosen for the first slide.
Portrait
- Aspect ratio: 4:5
- Dimensions: 1080 x 1350 pixels
Square
- Aspect ratio: 1:1
- Dimensions: 1080 x 1080 pixels

Profile picture and Highlights
Profile pictures and Instagram Highlights are the same size:
- Aspect ratio: 1:1
- Dimensions: 320 x 320 pixels (minimum), 1080 x 1080 pixels (recommended for high resolution)
Just keep in mind that these will display as circles, so you have to center the part of your photo or logo you want shown.
| Content type | Recommended size | Aspect ratio |
|---|---|---|
| Reel | 1080 x 1920 pixels | 9:16 |
| Story | 1080 x 1920 pixels | 9:16 |
| Feed/carousel portrait | 1080 x 1350 pixels | 4:5 |
| Feed/carousel square | 1080 x 1080 pixels | 1:1 |
| Feed/carouse landscape | 1080 x 566 pixels | 1.91:1 |
| Profile picture | 1080 x 1080 pixels | 1:1 |
| Highlight | 1080 x 1080 pixels | 1:1 |
The Best Instagram Photo Sizes for Engagement
If your goal is to maximize reach and engagement on Instagram, portrait content is your best bet. Over time, Instagram has also shifted toward vertical content formats that take up more screen space on mobile devices. That’s why, in general, Instagram content performance tends to follow this order:
Portrait > Square > Landscape
That doesn’t mean square or landscape posts are a no-go. But if you’re trying to stop the scroll, bigger visuals usually win.
No matter which format you choose, the key is making sure your content is high-resolution, easy to read on mobile, and properly centered. Otherwise, Instagram may crop important parts of your image, including text, products, or faces.
