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 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)
Maximum file size: 8MB
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.

You'll need to make sure that all of your images are within the aspect ratio range to correctly auto publish moving forwards.
