It’s traditional to refer to phones by their screen size and for the iPhone 12 mini, that number is 5.4 inches diagonally. But that number doesn’t tell the story at all. The phone is smaller than the traditional 4.7-inch-home-button iPhone design we saw from the iPhone 6 on through the 6S, 7, 8, and 2020 SE models, even though the screen itself is larger.
That’s because the 12 mini, just like the rest of the iPhone 12 line, has switched over to Apple’s more modern OLED screens and Face ID notch for unlocking. Those two features allow Apple to design the phone with minimal bezels and maximal screen.
