A bit more detail on why I gave up on Instagram: the tallest aspect ratio it allows is 1.24, while a postcard is 1.57 (5.5 inches by 3.5 inches). It means you have to crop 7/8 of an inch from every one. You would think that given that 5.5 by 3.5 has been a standard dimension for cards and photographs for at least 150 years and that phone screens are typically even more extreme (mine has aspect ratio of 1.75), that I would be able to post my postcard of Leavitts Falls in its original dimensions.
