His Majesty the Square is dead.

Until now, the 1:1 square format (1080 x 1080 pixels) was the undisputed king of Instagram. However, the platform has decided to adapt to new trends where vertical content is gaining ground.

The New Star Format: The Vertical Grid

Adam Mosseri, CEO of Instagram, has announced that the platform will prioritize vertical display, favoring images with an aspect ratio of 4:5 (1080 x 1350 pixels). This translates to taller photos that are better adapted to content consumption on mobile devices.
