Frequently Asked Questions

What size should Instagram posts be?

Square posts: 1080x1080px. Portrait: 1080x1350px. Landscape: 1080x566px. Portrait (1080x1350) gets the most feed real estate.

Instagram stories and reels should be 1080x1920 pixels (9:16 aspect ratio). This fills the full screen on mobile devices.

What is the Instagram profile photo size?
