OnePlus 8 and Galaxy S20 Ultra 5G, performance comparison

OnePlus 8 and Galaxy S20 Ultra 5G size comparison. Which to choose?

The size of the body has a big influence on the ease of carrying and one-handed operation. The narrower the width, the easier it is to firmly grasp and hold, but you also have to take into account the device's thickness. Also, if the width and height are smaller, its easier to operate one-handed since its easier to extend your fingers. On the contrary, if the width and height are large, it's difficult to fit in your pocket and is bulky even when put in a bag, and portability is impaired.

The OnePlus 8 has a width of 2.9 inches (72.9 mm), a length of 6.3 inches (160.2 mm), and a thickness of 0.3 inches (8 mm). Also, the Galaxy S20 Ultra 5G has a width of 3.0 inches (76 mm), a length of 6.6 inches (166.9 mm), and a thickness of 0.3 inches (8.8 mm).

Comparing the width and thickness of the body, the OnePlus 8 is smaller and more compact compared to the Galaxy S20 Ultra 5G. For that reason, the OnePlus 8 is easier to grip firmly and carry one-handed than the Galaxy S20 Ultra 5G. For that reason, we recommend the OnePlus 8.

Comparing the width and thickness of the body, there isn't a large difference in size between the OnePlus 8 and the Galaxy S20 Ultra 5G. For that reason their one-handed operability, portability, and bulkiness when carried is about the same. That's why I think it's better to compare them in terms of other aspects of performance and functionality.

Comparing the overall size of the two devices, there isn't a big difference in size between the OnePlus 8 and the Galaxy S20 Ultra 5G. For that reason the ease of carrying and use with one hand is about the same for both. That's why it is better to compare the two in terms of other aspects of performance and functionality.
