Samsung Galaxy S24 Ultra

The Samsung Galaxy S24 Ultra measures 6.39 inches (162.3 mm) tall, 3.07 inches (79.0 mm) wide, and 0.34 inches (8.6 mm) thick. It weighs 8.22 ounces (233 grams). This is Samsung’s largest and most feature-packed phone in the S24 lineup, with a built-in S Pen and a 6.8-inch display. This page lists the exact dimensions, comparisons with other flagship phones, and practical size information.

Dimensions

Weight

At 233 grams (8.22 ounces), the S24 Ultra is heavier than most smartphones. It weighs about the same as a hamster or a small bar of soap. The titanium frame contributes to both the weight and the durability.

Display

The screen is 6.8 inches diagonally, using Dynamic AMOLED 2X technology at 3120 x 1440 pixels (505 pixels per inch). The display has flat edges rather than the curved edges found on older Galaxy Ultra models.

Size comparison with other flagships

The S24 Ultra is slightly taller and wider than the iPhone 15 Pro Max, and about half an ounce heavier. It is noticeably larger than the standard Galaxy S24 in every dimension. The Pixel 8 Pro is nearly the same height but narrower and lighter.

Real-world size context

The S24 Ultra is longer than a US dollar bill (6.14 inches) by about a quarter inch. It is wide enough that most people cannot wrap their hand around it and touch thumb to fingertips. One-handed use requires the one-handed mode feature or a large hand.

The phone fits in most pants pockets but is noticeable. In slim-fit jeans, it creates a visible outline. With a case, the total thickness approaches 11 to 12 mm, which adds to the pocket bulk. The flat-edge design makes it sit more securely on flat surfaces compared to phones with curved sides.

S Pen dimensions

The built-in S Pen is 105.08 mm long and 4.35 mm in diameter, with a 0.7 mm tip. It stores inside the phone body at the bottom left corner and clicks into place magnetically. The pen adds no extra thickness to the phone because it fits within the existing chassis.

Case and accessory sizing

Galaxy S24 Ultra cases do not fit the S23 Ultra. Although the dimensions are similar (the S23 Ultra is 163.4 x 78.1 x 8.6 mm vs the S24 Ultra at 162.3 x 79.0 x 8.6 mm), the camera layout and corner shape changed enough to require new cases. The S Pen slot is in the same position on both models.

Screen protectors must be sized for the S24 Ultra’s flat display. Protectors from curved-screen models like the S23 Ultra will not lie flat on the S24 Ultra’s edges.
