What size is an Instagram post?

The square feed post is 1080×1080 pixels. Instagram displays it at 1:1, so matching that size keeps it sharp.

Why square instead of portrait?

Portrait (4:5) is allowed and shows up a bit bigger, but the square is the most predictable and the traditional feed look.

Will my photo be cropped?

With Cover, a non-square photo is cropped from the centre to fill the frame. Switch to Contain to keep all of it with padding.

Fit

Fills the frame, crops the overflow.

An Instagram feed post looks best as a 1080×1080 square. Instagram shows feed images in a 1:1 frame, and uploading at exactly that size means your photo stays sharp instead of being re-compressed and cropped unpredictably by the app.

Tips for a clean feed

Use the same size for every slide of a carousel so they line up.
Keep the square consistent across posts for a tidy profile grid.
Leave a little breathing room around faces and text near the edges.

Square, portrait or landscape?

Instagram also allows portrait (4:5) and landscape, but the 1080×1080 square is the most reliable and the classic look. By default the tool fills the square (Cover) and crops the rest; switch to Contain to keep the whole image.
