Mosseri shared that implementing taller images and videos is the company’s way of making the Instagram experience even more immersive. The change to your feed was made possible by the new 9:16 ratio, which replaced the standard square 1:1 ratio and alternative ratios that went up to 4:5. On May 3, Head of Instagram Adam Mosseri took to his personal IG account to announce the OG feed test, which enlarged photos and videos on the Home feed to take up more space on your screen. Users who’ve had access to the new Instagram feed test since the beginning might feel like the test never ended, but that’s not the case. Here’s what you need to know about the oversized pics and vids. If you’ve been wondering why your Instagram feed looks different, this photo and video test explains it all. Following a May 2022 test, Instagram launched a new feed test that super-sizes the photos and videos in your feed on June 16 to select users. If you’ve been seeing bigger photos and videos on your Instagram feed in recent weeks, don’t worry - it’s not an app glitch.
