Instagram keeps cropping your photo — the ratio rules behind it

2026-09-07

You post a photo and Instagram slices the top of someone's head off, or shaves the sides of a landscape. You didn't crop anything — Instagram did, and it didn't ask.

The rule it's following

Instagram's help page ("Image resolution for photos you share", checked 2026-08-28) states the boundaries: photos upload at up to 1080 pixels wide, and a photo keeps its original framing only when its aspect ratio is between 1.91:1 (wide) and 3:4 (tall). "Photos with an unsupported ratio are cropped to fit a supported one." Below 320 pixels wide it gets enlarged; above 1080 it gets scaled down.

What that means in practice

• A 16:9 landscape (1.78:1) fits — barely — but a wider panorama does not, and loses its edges.
• A full-height phone photo is 9:16 (0.56:1) — far taller than 3:4 (0.75:1) — so the top and bottom get cut. That's the beheaded-portrait effect.
• Square (1:1) always fits.

Crop it yourself, before Instagram does

Automatic cropping centers the cut, and centers are rarely where your subject is. Cropping the photo yourself to a supported ratio means you pick what survives. In our crop tool you set the ratio and drag the frame while seeing exactly what gets removed — it runs in your browser, with nothing uploaded.

Which ratio to pick

• 3:4 — the tallest allowed; fills the most feed space, the usual choice for portraits.
• 1:1 — safe everywhere, works in grids and profiles.
• 1.91:1 — the widest allowed; the practical ceiling for landscapes.

What we deliberately don't do

We don't add blurred bars or AI-extended edges to force a fit. Padding a photo to a ratio changes what the image is; that's an artistic call, not a default a tool should make for you.

The short version

• Allowed range is 1.91:1 to 3:4, width up to 1080px (Instagram Help, checked 2026-08-28).
• Outside the range, Instagram crops from the center — without asking.
• Crop to 3:4, 1:1 or 1.91:1 yourself so you choose what's lost.
