Moto X size comparison: excellent phone-to-screen size ratio19
In fact, the Moto X is not only shorter and narrower than the 5-inchers - its shrunken bezel makes it with less frontal surface than the fellow 4.7-inchers, like the Nexus 4, or the Ascend P6. In fact it is shorter, and only slightly wider than the 4.3" HTC One mini, which, of course, had to fit those BoomSound speakers somewhere.
Again, we might be looking at one of the best phone-to-screen-size ratios, where the crown is on the Sony Xperia ZL's head, and Motorola explained how it achieved that barely visible bezel. It stretches edge-to-edge, they say, molded carefully at the ends to fuse with the front housing for a seamless look and "the perfect balance between readability and one-handed use".
