BONUS: Best carousel sizes to auto-post on Instagram

Instagram has requirements for carousel dimensions.

If your post is not one of these sizes, it won’t be able to auto-post.

Your carousel must be:

  • Square: 1080x1080px (aspect ratio: 1:1)
  • Portrait: 1080x1350px (aspect ratio 4:5)
  • Landscape: 1080 x 566 pixels (aspect ratio: 1.91:1)

Can you mix different sizes in one carousel?

Not at the moment. All the images and videos within a carousel have to be the same size.

That’s it!

Have fun planning your Instagram posts!
