Are you ready to try Tailwind's Auto-Post feature to quickly schedule and post to Instagram in a breeze? Before you start, here is some information about the size and dimensions of the images that you can post using Auto-Post.


All Instagram posts you schedule with Auto-Post will automatically send at the times you've queued them for provided that the images you've scheduled and uploaded are in the correct aspect ratio as required by Instagram's API for automated publishing. (You can read more here: https://developers.facebook.com/docs/instagram-api/content-publishing

Image Requirements:

  • Maximum file size: 8MB

  • The format must be JPEG, PNG, BMP, and non-animated GIFs

  • Must be within a 4:5 to 1.91:1 aspect ratio range

  • Minimum resolution: 150×150 (lower resolutions will be scaled up to the minimum)

  • Maximum resolution: 1920×1080 (higher resolutions will be scaled down to the maximum)

All of your images must be within a 4:5 to 1.91:1 aspect ratio range to correctly publish. If they aren't at this ratio they will fail to send and will appear in your Scheduled page as a 'Failed Post'. These will need to be cropped to meet the requirements and then rescheduled.

Learn more about Failed Posts in our Knowledge Base article: Why are my posts failing?

How to ensure your images publish at maximum quality

The ideal size for a high-quality portrait image (recommended for marketing purposes for maximum screen real estate) is 1080 pixels wide by 566 pixels to 1350 pixels high.

The below chart shows the ideal resolutions for each type:

You can use this handy tool to check any resolution and see the aspect ratio though to see if it matches Instagram's requirements:
