Instagram Image Sizes (2026): Posts, Stories, Reels & Profile
The best all-around Instagram image size is 1080x1080 pixels for square posts, 1080x1350 for portrait posts (the tallest a feed photo can be), and 1080x1920 for Stories and Reels. Instagram scales every upload to a maximum width of 1080 pixels, so matching these exact dimensions before you post is the single most reliable way to keep your images sharp and stop the app from cropping or over-compressing them.
Instagram image sizes at a glance (2026)
Instagram displays feed images at a maximum width of 1080 pixels. Anything wider is downscaled; anything narrower is upscaled and looks soft. The height depends on the aspect ratio you choose, and Instagram only accepts feed aspect ratios between 1.91:1 (landscape) and 4:5 (portrait).
Pick your format first, then export at the exact pixel size below. Uploading at the native size means Instagram has no reason to re-crop or heavily re-compress the file.
- Square post: 1080 x 1080 px (1:1)
- Portrait post: 1080 x 1350 px (4:5) - tallest feed size, most screen space
- Landscape post: 1080 x 566 px (1.91:1)
- Story: 1080 x 1920 px (9:16)
- Reel: 1080 x 1920 px (9:16)
- Reel cover/thumbnail: 1080 x 1920 px (displays as 1015 x 1350 in the grid)
- Profile picture: at least 320 x 320 px, square, shown as a circle
- Carousel: 1080 x 1080 or 1080 x 1350 - all slides should share one ratio
Portrait 1080x1350 (4:5) is the best size for feed posts
A 4:5 portrait image at 1080x1350 pixels takes up the most vertical space Instagram allows in the feed, so it fills more of the screen as people scroll and tends to earn more attention than a square or landscape shot.
If your original photo is a different shape, resize it to 1080x1350 rather than letting Instagram crop it. Use resize to 1080x1350 pixels for an exact fit, or crop to a 4:5 ratio first if you need to control which part of the frame is kept. For a one-click preset, the Instagram resizer outputs the correct size for every format.
Square and landscape posts
The classic 1:1 square at 1080x1080 is still the safest choice for grids and carousels because it looks consistent no matter where it appears. Every slide in a carousel should use the same aspect ratio, or Instagram will crop the odd ones out to match the first slide.
Landscape 1.91:1 photos display at 1080x566. This is the shortest feed format and gives you the least screen height, so reserve it for wide scenery or images that genuinely need the horizontal framing. Match the exact ratio before uploading with the crop tool to avoid an automatic crop that cuts off edges.
Stories and Reels: 1080x1920 (9:16) plus safe zones
Stories and Reels are full-screen vertical at 1080x1920 pixels (9:16). The catch is that Instagram overlays interface elements on top of your image: the profile and menu row at the top, and captions, action buttons, and the send bar at the bottom.
Keep any important content - text, logos, faces, product details - out of the top ~250 pixels and bottom ~250 pixels of the 1920px canvas. That leaves a central safe zone of roughly 1080x1420 where nothing gets covered. Design your key message inside that band and treat the top and bottom as decorative margins.
- Canvas: 1080 x 1920 px (9:16)
- Top safe margin: keep content below the first ~250 px
- Bottom safe margin: keep content above the last ~250 px
- Usable safe zone: roughly 1080 x 1420 px in the center
- Reel captions/buttons live in the bottom third - avoid text there
Profile picture size
Upload a square profile photo of at least 320x320 pixels. Instagram stores it square but always displays it inside a circle, so anything in the corners of the frame is hidden.
Center your face or logo and leave breathing room around the edges so the circular mask doesn't clip it. A larger square such as 640x640 uploads cleanly and gives Instagram a sharp source to downscale from on high-resolution screens.
Why Instagram crops and compresses off-size uploads
Instagram enforces its own display rules. If your image is wider than 1080px, it is downscaled. If the aspect ratio falls outside 1.91:1 to 4:5, the app crops it to fit the nearest allowed ratio - which is where heads and captions get cut off. And every upload is re-encoded to JPEG at Instagram's compression settings, so a bloated file loses more quality in the process.
You get the cleanest result by handing Instagram a file that already meets its specs: exactly 1080px wide, an allowed aspect ratio, and a reasonable file size. Resize to the target dimensions with the pixel resizer, and if the file is still heavy after export, run it through an image compressor so less quality is lost in Instagram's own re-compression. Because imgbox processes everything in your browser, your photos are never uploaded to a server while you prepare them.
Frequently asked questions
What is the best Instagram post size in 2026?
1080x1350 pixels (4:5 portrait) is the best size for feed posts because it uses the most vertical screen space allowed. Use 1080x1080 (square) for carousels and grids where consistency matters most.
What size is an Instagram story?
1080x1920 pixels at a 9:16 aspect ratio. Keep important content out of the top and bottom ~250 pixels so interface elements don't cover it.
What is the maximum image size Instagram allows in the feed?
Instagram scales feed images to a maximum width of 1080 pixels and accepts aspect ratios from 1.91:1 (landscape) to 4:5 (portrait). The tallest feed image is 1080x1350.
What size should my Instagram profile picture be?
At least 320x320 pixels and square. It's displayed as a circle, so center your face or logo and keep the corners clear.
Why does Instagram crop or blur my photos?
It crops when your aspect ratio is outside the allowed 1.91:1 to 4:5 range, and it blurs when your image is wider than 1080px and gets downscaled, or when a heavy file is re-compressed. Uploading at 1080px wide in an allowed ratio prevents both.
Are Instagram Reels and Stories the same size?
Yes, both use 1080x1920 pixels (9:16). Reels place captions and buttons in the bottom third, so keep text out of the lower portion of the frame.
