About Instagram Portrait

Instagram portrait posts at 1080×1350 pixels (4:5) take up the most vertical space in the feed, making them ideal for maximizing visibility. This format works exceptionally well for fashion, food photography, and any content where vertical framing enhances the composition. Portrait posts consistently outperform square and landscape formats in engagement metrics. Keep your subject centered and use the extra height for context and storytelling.
