Ever opened Instagram and felt like you were walking into your own house, only to find someone moved the fridge into the bathroom? That’s basically how everyone felt when the navigation bar suddenly flipped. One day your thumb knows exactly where the "post" button is, and the next, you're accidentally staring at a Reels feed you didn't want to see.
It's annoying. Truly.
But there’s actually a method to the madness. Instagram didn't just wake up and decide to ruin your muscle memory for fun. They're in the middle of a massive identity crisis, trying to figure out how to stop everyone from leaving for TikTok while also dealing with the fact that we don't post to our "grids" like we used to.
Why did Instagram change layout? The DM and Reels Pivot
The short version? You aren't "posting" enough, but you are "chatting" more than ever.
Adam Mosseri, the guy who runs Instagram, has been pretty vocal about this. In a series of updates through 2025 and into early 2026, he’s basically admitted that the old-school feed—where you scroll through square photos of your friends' brunch—is dying. Or, well, it's not where the "growth" is. According to Meta's internal data, almost all the time people spend on the app now happens in two places: Reels and DMs.
That's why the layout changed.
They moved the DM (or "Chat") icon to the bottom navigation bar because that’s where your thumb lives. They want to turn Instagram into a messaging app that happens to have a video feed attached to it. By putting DMs right in the center or just a quick tap away, they’re betting that you’ll stay on the app longer if you’re talking to a friend rather than just mindlessly scrolling.
It’s all about retention. If you're in a group chat, you're "locked in." If you're just looking at photos, you might get bored and close the app.
The TikTok-ification of Your Profile
You probably noticed the grid looks weird now too. For years, the 1:1 square was the law of the land. Now? It’s all about the 4:5 vertical rectangle.
This change was a direct response to the way we hold our phones. We hold them vertically. When you force a vertical photo into a square crop, you lose detail. Instagram realized that if they wanted to compete with TikTok's full-screen immersion, they had to ditch the square.
Of course, this absolutely wrecked the "aesthetic" of thousands of photographers and influencers who spent years planning their grids. If you had a "checkerboard" pattern or those cool "split-image" posts that span three blocks, the new rectangular layout likely chopped them into a chaotic mess.
The "Data-Driven" UX Trap
Instagram uses something called A/B testing on a scale that’s honestly kind of terrifying.
They don't just roll out one layout to everyone at once. They give 10% of users one version, another 10% a slightly different one, and then they watch. They see which group clicks more ads, which group stays on the app for 30 seconds longer, and which group sends more Reels to their friends.

If the data shows that moving the "Create" button to the top-left makes people watch 5% more video content, they’ll do it. Even if 100,000 people go on Twitter (or X) to scream about how much they hate it.
Muscle Memory vs. "Intentional Friction"
There’s this concept in design called "friction." Usually, designers want to remove it. You want things to be easy. But sometimes, Instagram wants to slow you down.
By moving the "Post" button away from the center of the screen, they're making it slightly harder to share a static photo. Why? Because they want you to consume first and create second. They’ve realized that a platform with too many creators and not enough "watchers" becomes saturated. They are "grooming" new users to be consumers of Reels rather than posters of photos.
What’s Next? (And How to Fix Your Feed)
Honestly, the "classic" Instagram isn't coming back. The 2026 updates have doubled down on AI-integrated search and even longer Reels—some reaching up to 20 minutes.
But you aren't totally powerless. If you hate the "Recommended" content that the new layout keeps shoving in your face, there are a few things you can actually do:
- The "Following" Feed: Tap the Instagram logo in the top-left corner. You can switch to a "Following" feed which is strictly chronological and only shows people you actually know. It’s the closest thing to "Old Instagram" we have left.
- Tune Your Algorithm: There's a relatively new setting (look under "Suggested Content") that lets you literally tell the AI what topics you hate. If you’re tired of seeing fitness influencers, you can mark those topics as "Not Interested" in bulk.
- Adopt the 4:5 Ratio: If you’re a creator, stop posting squares. The layout has changed for good. Start framing your shots with the vertical rectangle in mind so the "auto-crop" doesn't cut off your head.
The app is morphing into a hybrid of WhatsApp and TikTok. It's messy, and the transition hasn't been smooth, but from Meta’s perspective, it’s a survival tactic. They’re following the eyeballs, and right now, the eyeballs are in the DMs.
Next Steps for You
Check your "Content Preferences" in settings. Most people don't realize you can actually "Snooze" all suggested posts in your feed for 30 days at a time. It’s a temporary fix, but it clears out the "algorithm slop" and lets you see your friends again. Also, if your grid looks wonky, go into your profile and use the "Edit Grid" tool—Instagram finally added a way to reorder and crop thumbnails manually to help fix the mess they made with the rectangular update.
