Samsung Galaxy S25 Ultra Dimensions

The Samsung Galaxy S25 Ultra measures 77.6 mm wide by 162.8 mm tall, with a thickness of 8.2 mm. It weighs 218 grams, which gives it a solid but manageable feel in hand. The device features a 6.9-inch display, which combined with its 77.6 mm body width determines how it feels during one-handed use. Placed next to a standard credit card (85.6 mm x 54.0 mm), the Samsung Galaxy S25 Ultra is noticeably taller.

Compared to a standard passport book (88.0 mm x 125.0 mm), the Samsung Galaxy S25 Ultra is narrower, making it easier to slide into a travel wallet. At just 8.2 mm thick, the Samsung Galaxy S25 Ultra is slimmer than most pencils, meaning it disappears into a pocket without creating an obvious bulge.

Weighing 218 grams, the Samsung Galaxy S25 Ultra sits in the mid-range for its category. It has enough heft to feel premium and stable in the hand, while remaining comfortable for daily carry. You will feel it after long reading sessions, but it is not burdensome.
