Instagram image sizes, 2026.
Every format. One cheat sheet.
Eight formats, one constant (1080px wide), and one recent plot twist (the grid went 3:4). Bookmark the table below and never squint at a blurry, badly-cropped upload again. Every number current for 2026.
Every Instagram size that matters
| Format | Pixels | Ratio | The one thing to know |
|---|---|---|---|
| Feed post (portrait) | 1080 × 1350 | 4:5 | The workhorse — max feed space |
| Feed post (grid-native) | 1080 × 1440 | 3:4 | Zero cropping on the new grid |
| Feed post (square) | 1080 × 1080 | 1:1 | Classic; grid crops it to 3:4 |
| Feed post (landscape) | 1080 × 566 | 1.91:1 | Smallest presence — use sparingly |
| Story | 1080 × 1920 | 9:16 | Keep top/bottom ~250px clear |
| Reel | 1080 × 1920 | 9:16 | Bottom third + right edge = UI zone |
| Profile picture | 320 × 320+ | 1:1 → circle | Center subject, test at thumbnail |
| Grid preview | auto-crop | 3:4 | All posts crop to this on profiles |

Three rules explain every number in the table
Rule one: 1080 wide, always. Instagram serves images at up to 1080px wide and recompresses everything on upload. Export wider and you invite aggressive downscaling; export narrower and you get upscaled mush. Every format in the table shares that width for a reason, and matching it is 90% of the “why is my upload blurry?” cure — the rest is exporting JPG at high quality (or PNG for text-heavy graphics).
Rule two: vertical owns the screen. Phones are tall, so tall formats get the attention: a 4:5 post occupies dramatically more feed than a landscape one, and stories/reels take the full 9:16 canvas. The practical consequence: compose vertical by default and reserve landscape for content that genuinely needs it. Details per format live in the post, story and reel guides — including the story/reel safe zones where Instagram's own UI covers your content.
Rule three: the grid crops to 3:4 now. The newest rule, and the one that broke old habits: profile grids preview every post as a 3:4 portrait tile. Squares lose their edges, landscapes lose everything but the middle. Compose with the center safe, export 4:5 or 3:4, and rescue old tiles with the Adjust-preview trick from the grid layout guide.
Sizes are the floor, not the ceiling
Correct dimensions make content eligible to perform — sharp, uncropped, full-size in feed. What it does from there is the usual game: posting into your audience's active windows, captions that hook before the fold, and knowing whether each post gained or cost you followers — which the followers tracker answers with names and timestamps. Pixel-perfect is the entry fee; the tracker tells you if the show was any good.
Image sizes, answered
What are the Instagram image sizes for 2026?
The ones that matter: feed posts 1080×1350 (4:5 portrait) or 1080×1440 (3:4), square 1080×1080, landscape 1080×566; stories and reels 1080×1920 (9:16); profile picture 320×320 displayed in a circle; and the profile grid now previews everything at 3:4. Width 1080px is the constant across all of them.
What's the best size for a normal feed post?
1080×1350 (4:5) remains the workhorse: maximum feed real estate, universally supported, and it crops gracefully to the 3:4 grid. If you optimize for the profile grid specifically, 1080×1440 (3:4) previews with zero cropping.
Why do my images look blurry after uploading?
Instagram recompresses everything, and two things make it visibly worse: uploading wider than 1080px (aggressive downscaling) or much smaller (upscaling). Export at exactly 1080px wide, JPG at high quality or PNG for graphics, and blur mostly disappears.
What changed with the grid recently?
Instagram moved profile grid previews from 1:1 squares to 3:4 portrait tiles. Posts themselves still support the old ratios, but the grid crops them to 3:4 — which is why square-composed accounts suddenly look awkwardly cropped, and why new exports should keep key content centered.
What size should Instagram stories be?
1080×1920 (9:16), full-screen vertical. Keep text and stickers inside the safe zones — roughly the top and bottom 250px get overlapped by the UI (camera, reply bar). Same canvas applies to reels.
What's the profile picture size?
Upload at least 320×320 (1:1); it displays tiny and cropped to a circle. Center the subject, avoid corner details, and test at thumbnail size — the full breakdown lives in our profile picture guide.
Do reels need a different size than stories?
Same canvas (1080×1920, 9:16), different safe zones: reels show captions, buttons and your handle over the video, so the bottom third and right edge need to stay clear of anything important. The reel guide maps the exact zones.
Does image size affect reach?
Indirectly but really: portrait formats occupy more feed space (more seconds of attention), correctly sized images skip ugly recompression, and posts that look sharp get the engagement blurry ones don't. Size is table stakes, not a growth hack.
