The Samsung Galaxy S26 Ultra is Samsung’s biggest current flagship phone, and its size is the first thing most buyers ask about before ordering one. It has a 6.9-inch display, but the screen size alone does not tell you how the phone feels in your hand or whether it fits comfortably in your pocket. In this guide, you will find the Samsung Galaxy S26 Ultra dimensions in inches, centimetres and millimetres, its exact weight, and simple comparisons with the iPhone 18 Pro Max — so you can picture its real size before you buy it.

How Tall Is the Samsung Galaxy S26 Ultra?
At 6.44 inches (16.36 cm) tall, the Samsung Galaxy S26 Ultra is about as tall as a standard ballpoint pen, and 0.30 inches taller than a US dollar bill, which is 6.14 inches long. For most people, this is a two-hand phone for typing long messages, though one-handed use is possible if you have larger hands.
How Wide Is the Samsung Galaxy S26 Ultra?
The phone is 3.07 inches (7.81 cm) wide. That width is what decides whether it feels comfortable in one hand. It is the same width as the iPhone 18 Pro Max, which is also 3.07 inches wide, so the two phones feel very similar across the palm.
How Thick Is the Samsung Galaxy S26 Ultra?
At 0.31 inches (7.9 mm) thick, the Samsung Galaxy S26 Ultra is about one-third of an inch thick — roughly the thickness of ten stacked credit cards. The raised camera area on the back adds a little more.
How Much Does the Samsung Galaxy S26 Ultra Weigh?
The Samsung Galaxy S26 Ultra weighs 214 grams (7.55 ounces), just under half a pound. That makes it 35 grams lighter than the iPhone 18 Pro Max. For comparison, 214 grams is about the weight of a small paperback book, or a little less than a can of soup.
Samsung Galaxy S26 Ultra vs iPhone 18 Pro Max: Size Comparison
| Feature | Samsung Galaxy S26 Ultra | iPhone 18 Pro Max | Difference |
|---|---|---|---|
| Display | 6.9 in | 6.9 in | Same |
| Height | 6.44 in (163.6 mm) | 6.43 in (163.4 mm) | 0.01 in taller |
| Width | 3.07 in (78.1 mm) | 3.07 in (78.0 mm) | Same |
| Thickness | 0.31 in | 0.34 in | 0.03 in thinner |
| Weight | 7.55 oz (214 g) | 8.78 oz (249 g) | 1.23 oz lighter |
Both phones have the same 6.9-inch display and almost exactly the same height and width, so the choice comes down to thickness, weight and the built-in S Pen — not screen size. The Galaxy S26 Ultra is thinner and lighter, and its 6.9-inch QHD+ Dynamic AMOLED 2X display runs at 120 Hz.
Does the Samsung Galaxy S26 Ultra Fit in Your Pocket?
Yes, for most regular trouser and jacket pockets. At 6.44 inches tall and 3.07 inches wide, it slides into a standard pocket, though it will fill it more completely than a smaller phone. In tight jeans pockets it may feel snug when you sit down, so a jacket pocket or bag is more comfortable for all-day carrying.
