n a long-awaited move, Instagram is now supporting the native 3:4 aspect ratio used by most smartphone cameras, eliminating the need to crop vertical photos before posting. The update, announced by Instagram head Adam Mosseri on Threads, brings a small but impactful change for users who have long been frustrated by the app’s restrictive formatting options.
Historically, Instagram capped the vertical photo format at 4:5, slightly squarer than the typical 3:4 aspect ratio found in most phone cameras, including the iPhone. This limitation often forced users to either crop the top and bottom of their images or rely on third-party apps to add borders that preserved the original composition.
Now, that’s no longer necessary. Whether you’re posting a single image or a full carousel, 3:4 images will appear as they were captured — no black bars, no edits, no compromise on framing.
While the shift might seem minor, it’s part of a broader trend in how Instagram handles visual content. The platform, originally built around a strict square-photo aesthetic, has been gradually reshaping itself to accommodate the vertical-first habits of today’s users. Earlier this year, Instagram began displaying photos in rectangular frames within user profiles, signaling a steady move away from its grid-based origins.
The ability to post 3:4 images natively should be especially welcome for mobile photographers, creators, and anyone who prefers to share content without sacrificing image integrity. It also simplifies the process of editing and posting directly from the camera roll, aligning the app more closely with real-world photo capture standards.
Instagram has not announced whether it plans to support even taller ratios — such as 9:16, commonly used in Stories and Reels — in the main feed, but the acceptance of 3:4 suggests the platform is still evolving alongside user behavior.
The change is rolling out now, and users can begin uploading 3:4 images immediately without needing to update the app.
