The short answer

For most posts, use 1080 × 1350 px (4:5 portrait): it fills the most screen space in the feed. Use 1080 × 1440 px (3:4) if you want the photo to match the profile grid exactly, and 1080 × 1920 px (9:16) for Reels and Stories. Instagram displays everything at 1080 px wide, so exporting wider adds file size without extra sharpness.

How to post without cropping

01
Pick the ratio

Decide where it will be seen most: the feed (4:5), the profile grid (3:4) or full screen (9:16).

02
Export at 1080 px wide

Resize to the exact pixels below and save as JPG (photos) or MP4 (video).

03
Check the crop before posting

In the upload screen, make sure nothing important sits near the edges, then share.

Every Instagram size at a glance

Portrait post · 4:5

1080 × 1350 px. The recommended default for feed photos and ads — the tallest ratio the feed shows in full.

Tall post · 3:4

1080 × 1440 px. Matches the 3:4 preview Instagram uses on the profile grid, so the tile isn't trimmed.

Square post · 1:1

1080 × 1080 px. The classic format; shows uncropped in the feed but smaller than portrait.

Landscape post · 1.91:1

1080 × 566 px. Works for wide shots, but takes up the least screen space in the feed.

Reels · 9:16

1080 × 1920 px. Full-screen vertical video; keep text away from the bottom, where the caption and buttons sit.

Stories · 9:16

1080 × 1920 px. Same as Reels; leave roughly the top and bottom 250 px clear of important text.

Carousel

Up to 20 photos or videos in one post (in the app). The first item's ratio sets the frame for the whole carousel.

Profile photo

Shown at 320 × 320 px inside a circle. Upload a larger square (e.g. 640 × 640) and keep the subject centred.

Why Instagram crops your photo

When you post from the app, the feed shows photos between 1.91:1 (wide) and 3:4 (tall) without cropping; anything wider or taller is cropped to fit. The profile grid now previews posts at about 3:4, so a 4:5 photo loses a thin strip on the left and right of its grid tile. Keep the subject centred and both views stay clean.

Sizes change — double-check in the app

Instagram adjusts its formats from time to time (the 3:4 grid and 20-item carousels are recent changes), and some limits differ when posting through scheduling tools or the API. The upload screen always shows the crop that will actually be used.

Tips for sharp, uncropped uploads

Export at exactly 1080 px wide — Instagram resizes anything else, and upscaling a small image only makes it softer. Save photos as high-quality JPG in sRGB colour so they don't look washed out. For Reels and Stories, keep important text inside the centre safe area. And if you need the original file of a public post — your own, or one you have the right to use — paste its link into the downloader above to save it at the full size Instagram serves.
