Samsung Galaxy S26 Ultra vs S25 Ultra: Side by Side Comparison – Design and Dimensions
Samsung has released the Galaxy S26 Ultra with design optimizations, and we’ve conducted its side-by-side comparison with the Galaxy S25 Ultra to highlight everything new in this latest flagship.
The need for such an exploration is evident from the divided user opinions. On one side, people are saying that it’s a refined version, while others are weighing in with “nah, it’s the same as S25 Ultra”. So, we decided to break into the conversation and tell you what you should know.
Galaxy S26 Ultra vs S25 Ultra – front
Last year, Samsung broke away from the Note series and adopted curved corners. Though reviewers saw this as a mere frame radius inclusion but it’s more like the end of an era. An era that made Note and Ultra look different from other premium phones in the market.

Building on the new design schemes, the S26 Ultra has increased the corner radius. After this change, the S26 Ultra’s symmetry aligns more with the base and Plus models. Basically, they are on the same page now.

Both phones bring a 6.9-inch QHD Dynamic AMOLED display, but the S26 Ultra appears a bit wider. You can only spot this difference in a side-by-side comparison. Samsung’s official specs sheet backs this observation. The S26 Ultra is 78.1mm wide and 163.6mm tall. On the other hand, the S25 Ultra is 77.6mm wide and 162.8mm tall. The new flagship is also taller and thinner than its predecessor despite offering the same display size.

Galaxy S26 Ultra vs S25 Ultra – frame
The frame is now aluminium, degrading from the titanium used in S25 Ultra. Some might argue that the build quality has declined, but it appears to be good overall.
The volume and power keys are on the right, and the USB-C port, SIM tray, microphone, and S-pen are at the bottom. That said, all of the side features are the same as the previous version, except for the S-Pen, and its clicker button had to adopt the new curves.

Galaxy S26 Ultra vs S25 Ultra – Rear
The back of both phones has a matte finish protected with Corning Gorilla Glass, yet the S26 Ultra has a more vibrant color. Unlike the S25 Ultra, the new model comes with a camera island.
The camera layout is the same as last year, but it no longer looks cheap with the addition of integrated camera crowns, which closely resemble the Galaxy Z Fold 7 but look better on the S26 Ultra.

That’s where Samsung received online criticism for gluing the camera rings around the S25 Ultra’s cameras. I guess the company has learned from the mistakes and brought a more integrated look to this year’s flagship.
With camera design enhancement, you can no longer put the phone on a flat surface, which is a kind of harsh reality, as it will wobble all the time. In that case, you’d better put on a cover on this device.
Conclusion
This comparison reveals that the Samsung Galaxy S26 Ultra is wider, taller, thinner, and looks better than the S25 Ultra. These optimizations stand tall on top of the software and hardware improvements, such as the privacy display, improved performance, cameras, and software. This is a perfect Android flagship for first-time buyers; still, we don’t recommend it as an upgrade for the S25 Ultra users.
