Instagram feed preview

Shows your image cropped to the square your profile grid uses, which is not the shape you posted — a 4:5 portrait loses its top and bottom on the grid.

The grid crop is the thing people plan for least and notice most. Your feed shows a 4:5 portrait in full, but your profile grid crops the same post to a square from the middle, cutting roughly 12.5 percent off the top and the bottom. Text near either edge survives in the feed and disappears on the profile. If your grid is part of how the account reads — and for a brand or a portfolio it usually is — compose so the important content sits inside the central square and treat the extra portrait height as breathing room rather than as content.
