Instagram has just made a subtle but meaningful update: the platform will now fully support photos shot in the native 3:4 aspect ratio, which is the default format for most smartphone cameras, including iPhones.
The change means no more unwanted cropping or black borders when uploading standard vertical images.
Announced by Instagram head Adam Mosseri on Threads, the update ensures that what users capture with their phone cameras is now displayed exactly as shot on the platform.
“Instagram now supports 3:4 aspect ratio photos – the format that almost every phone camera defaults to. From now on, if you upload a 3:4 image, it’ll now appear just exactly as you shot it.”
A Win for Visual Purists
Until now, Instagram capped vertical photos at a 4:5 aspect ratio, which often meant users had to crop their photos or resort to workarounds to maintain their full framing. With this change, users can post both single images and carousels in 3:4 without sacrificing any part of their composition.
Instagram has even shared examples showing the difference between 3:4 and 4:5 formats, highlighting how much cleaner and true-to-original the new default appears.
Instagram Moves Further from Its Square Roots
This update reflects Instagram’s broader shift away from its original square-only format. Earlier this year, the platform also introduced rectangle-framed thumbnails in user profile grids to better accommodate vertical content, which now dominates both photo and video formats.
Though small, this latest update is a nod to photographers—both professional and casual—who care about detail and framing. For anyone tired of trimming their carefully composed shots, this is a welcome change.
