What size are Instagram carousel images?
Instagram carousels support square (1080×1080), portrait (1080×1350), and landscape (1080×566) images. The first image sets the aspect ratio for all slides in the carousel.
How many images can I add to an Instagram carousel?
Instagram carousels support up to 20 images or videos per post. Each slide should use the same aspect ratio for a consistent viewing experience.
What is the best aspect ratio for carousels?
Portrait (4:5) carousels at 1080×1350 take up the most screen real estate in the feed, increasing engagement. Square (1:1) at 1080×1080 is the most versatile option.
