About Instagram Post
Instagram posts perform best at 1080×1080 pixels. Larger images are automatically compressed by Instagram, which can degrade quality. Square images fill the most screen real-estate in the feed, making them ideal for engagement. Always start with a high-resolution source image. Avoid excessive text overlays that may become unreadable after compression. For carousel posts, maintain consistent dimensions across all slides. The aspect ratio for feed posts can range from 1.91:1 to 4:5, but 1:1 remains the safest choice for consistent display across all devices and placements.
