Instagram supports numerous formats, and mastering them is essential for visual creators. Each format—posts, stories, reels, and ads—has distinct requirements that affect how it is displayed in the feed. First, choose your target format. Adjust the aspect ratio before resizing to avoid unexpected cropping by the app's interface. Stories and reels require extra care because captions and buttons often overlap the content edges. Ensure that faces and text remain within the central safe zone. Use high-resolution source files but keep file sizes manageable to avoid heavy compression. Export in the correct format and always test your upload. Instagram renders differently on iOS and Android, so checking your work on various devices is highly recommended.
