Instagram’s 2025 Grid Evolution

Embrace New Post Formats to Stay Ahead

With extra vertical space, you can tell richer stories.
Instagram’s latest update is shaking up the way content appears in the grid. Say goodbye to the strict square format and hello to portrait-oriented posts! This exciting change brings new opportunities to elevate your content, but it’s also catching some creators off guard. For years, Instagram’s grid has been synonymous with the classic square format (1:1 ratio), requiring posts to be 1080 x 1080 pixels. While vertical formats like Stories and Reels have been part of the platform for a while, the grid remained resolutely square—until now. Instagram is introducing support for portrait-oriented posts with a 4:5 aspect ratio, offering a taller canvas to showcase your content.
