The Secret to Instagram Growth
While Instagram started as a square-only app, the algorithm now favors vertical 4:5 portrait images (typically 1080 x 1350 pixels). Why? Because a 4:5 image physically takes up more space on a user's smartphone screen than a square or landscape photo. It commands the viewer's full attention, stops the scroll, and drastically increases engagement and 'dwell time.' Use our tool to crop your landscape shots into powerful vertical posts.
