Oppo K7 5G and vivo V15 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 Oppo K7 5G has a width of 2.9 inches (74.3 mm), a length of 6.3 inches (160.3 mm), and a thickness of 0.3 inches (8 mm). Also, the vivo V15 has a width of 3.0 inches (75.9 mm), a length of 6.3 inches (161.2 mm), and a thickness of 0.3 inches (8.5 mm).

Comparing the width and thickness of the body, there isn't much difference between the Oppo K7 5G and vivo V15 in terms of size. For that reason, the ease of gripping and carrying the devices in one hand is about the same for both. Therefore it's better to compare them in terms of performance and functionality.

Comparing the width and thickness of the body, there isn't a large difference in size between the Oppo K7 5G and the vivo V15.
