Alleged dummy units of the Galaxy S26 lineup leaked yesterday, showing off their iPhone 17 Pro-like design. It also confirmed that Samsung’s 2026 flagship lineup will finally feature built-in magnets for native Qi2 magnetic wireless charging support. Now, another leak has revealed the Galaxy S26 Ultra’s alleged dimensions — months before the phone’s probable release.

A leak from mid-July indicated the Galaxy S26 Ultra might pack an even bigger display than the S25 Ultra. Samsung would seemingly fit in the larger 6.89-inch panel by slimming down the bezels. Turns out, that might not be entirely accurate if the leaked dimensions are anything to go by.

Based on the dimensions shared by @UniverseIce, the Galaxy S26 Ultra will measure 163.4mm tall and 77.9 mm wide. That’s 0.6 mm taller than the S25 Ultra and 0.3 mm wider. The Galaxy S25 Ultra is already a big phone, so even a slight increase in dimensions can affect its ergonomics and make it unwieldy and almost impossible to use one-handed.

Samsung will seemingly circumvent this by further rounding the edges of the S26 Ultra — a throwback to the 2021 Galaxy S21 Ultra. This minor design change should improve the Ultra flagship’s ergonomics, making it easier to hold and slip into pockets.

The rounded corners won’t be the only major design change Samsung will supposedly make to its 2026 flagship. It’s also apparently going to revive the camera island design, which will house three lenses. The move will provide the company with more internal space, which would be required to fit in the bigger camera sensors.

Rounder and thinner design at the expense of battery capacity

Past leaks also indicate Samsung wants to make the S26 Ultra less than 8mm thick, down from the 8.2mm waistline of the S25 Ultra. While the sleeker and rounder design sounds appealing, it will purportedly come with a major trade-off: Samsung will reportedly stick with the same 5,000mAh battery as found on its last few flagship phones for another year.

To make up for it, the phone could support faster 60W wired charging speeds, but that might not always be enough, especially for power users.
