Instagram has been supporting non-square images since August 2015. At the time, it was a huge change for the platform. Rectangular portraits and landscape photos can comfortably sit on your grid without needing to be cropped. The key factor is to have the right width-to-height ratio – just use our recommendations from above. The square format is still the default shape when you originally upload the file. Then, you have the option to leave it or change dimensions to get the entire photo in the frame. Remember that the edges get chopped off when you go to a user’s profile and browse their feed. If you want your account to look universally good, that’s something to keep in mind.
