How thin and light is the new Samsung Galaxy S26 Ultra? It set new records

Until last year, it seemed like modern Galaxy smartphones couldn't or wouldn't get any thinner than they already were. Then came the ultra-thin Galaxy S25 Edge to confirm Samsung's newfound commitment. And now, even the latest Galaxy S26 Ultra is walking the same path laid down by the Edge in 2025.

To be clear, the Galaxy S25 Edge retains the title of Samsung's thinnest slab-type smartphone ever made, thanks to its 5.8mm profile. Even so, the new Galaxy S26 Ultra flagship adopts a similar philosophy: it is the thinnest Ultra ever made. It's also almost the lightest, with one exception.

The Galaxy S26 Ultra is 7.9mm-thin. It is the thinnest Ultra model ever made, and that includes the Note 20 Ultra, as you can see in the list below.

Granted, 7.9mm still a few millimeters away from the Edge’s record of 5.8mm. Still, it officially means that the Galaxy S26 Ultra is the slimmest Ultra model to date. It's almost a miracle that the S Pen fits inside that chassis.

The Ultra saga began six years ago, in February 2020, when Samsung unveiled the first model with a Space Zoom camera: the Galaxy S20 Ultra.

Back then, slimness clearly wasn’t the goal. The S20 Ultra measured 8.8mm, and while the Galaxy Note 20 Ultra slimmed down to 8.1mm, it took a few years for the series to approach that figure again.

The S26 Ultra is not just thinner. At 214 grams, it’s also among the lightest Ultra models to date.

Technically, only the Note 20 Ultra was lighter at 208 grams. But aside from that exception, the Galaxy S26 Ultra is the lightest device in the Galaxy S Ultra lineup. Here's how all the Ultra models compare.

All things considered, that’s impressive. The phone still includes an S Pen and uses an aluminum frame rather than titanium.

Considering how strongly Samsung focused on highlighting the benefits of titanium for the Galaxy S25 Edge last year, this switch to aluminum seems unusual. But if anything, the new Galaxy S26 Ultra shows Samsung can keep making thinner and lighter phones without relying on exotic materials.
