Instagram is testing a new profile grid layout that features rectangular images instead of the squares you're used to. In an Instagram story, Adam Mosseri has revealed that the app is testing a vertical grid for users' profiles. He explained that the original square grid was designed back in the day when the app only allowed users to upload square photos. Those days are long gone, and the vast majority of Instagram uploads are apparently vertical, specifically 4 x 3 images and 9 x 16 videos. He called cropping those uploads down to square as "pretty brutal."

When you click on Instagram's video tab, you'll already see a rectangular grid, so the experimental layout won't look terribly unfamiliar. In fact, the test profile looks exactly the same, based on a screenshot that a user posted on Threads, except the grid includes photo posts and not just videos. A spokesperson told The Verge that the test has only rolled out to a small number of users and that the Instagram team will listen to feedback before expanding the redesigned grid's availability.

Based on an old post by reverse engineer Alessandro Paluzzi, the app has been working on the new rectangular grid layout since at least 2022. It looks like the test is making its way to more users — and it seems like not everyone's happy about it. Mosseri posted his Story in response to a comment submitted to his "Ask Me Anything" session, pleading for the app not to kill the old layout.
