Post size and profile preview are different
An uploaded image is not always displayed uncropped in a profile thumbnail. The tool lets you inspect full posts and a simulated profile crop separately. Instagram’s photo help page describes ratios from 1.91:1 to 3:4 and images up to 1080 pixels wide.
Build the full canvas first
For a profile grid, multiply the tile width by 3 and the tile height by the number of rows. A nine-post layout using 1080 × 1440 tiles needs a 3240 × 4320 canvas. Apply one crop to the full canvas, not a different crop to each tile.
Keep important details away from seams
Faces, small text, and logos can become difficult to read when split across posts. Preview both the full image and the individual posts before exporting. A low-resolution source will not gain detail simply because it is enlarged.
