Adapting to the New Norm: The new default ratio is 4:5, or 1080 x 1350 pixels, which conveniently matches the vertical photos most smartphones capture these days.

Even though we are loyal fans of the iconic square posts, Instagram insists the change makes content more engaging and eye-catching on mobile screens. Sadly, there’s no going back—squares are no longer the standard, and we’ve all got to embrace this vertical reality (especially when we consider how many users access the platform on their mobile devices).
What About Older Posts?
If your grid suddenly looks disjointed, you may need to revisit older images or Reels covers designed for a square layout. It might feel like a hassle, but realigning them for this new aspect ratio will keep your feed looking cohesive. And don’t forget to check how your posts display on both mobile and desktop—sometimes what looks great on a phone might get cropped unexpectedly on a larger screen.
Why Is This Happening?
Instagram wants to keep your eyes on the content. Vertical posts fill smartphone screens more effectively, creating a more immersive, dynamic experience. And while it’s normal to miss the reliable square, early adopters often discover that this new format can actually boost engagement. Think of it as a necessary evolution to stay ahead in the ever-changing world of social media.
So, what are the dimensions I need to know?
Instagram is still supporting traditional dimensions for differing types of content however, it may not display the way you want it to. Something to consider if you are priding yourself on having an aesthetically pleasing profile grid.
Keeping Your Feed Cohesive
The key to a polished, consistent feed in this new environment is planning. If you still love the clean look of a square, you can centre your subject, so any automatic cropping doesn’t cut out important details. Using a feed-planning tool is an excellent way to spot any misalignment before you publish. This useful template will help:
Embrace the Change
While the new rectangular format can feel like a curveball, it gives your content more space to shine—literally filling up more screen real estate. If you’re feeling nostalgic for the days of uniform squares, remember that Instagram has always been about creativity and experimentation. The faster you adapt, the quicker your feed (and brand) will stand out in 2025’s version of the platform.
