Portrait 4:5 posts take up the most space in the Instagram feed, so they get noticed more than square or landscape ones. Instagram displays them at 1080 × 1350 pixels — anything else gets cropped or squashed.
Your photo is cropped from the centre to the exact shape and resized with high-quality resampling — all inside your browser, so it’s never uploaded.
