In an 18:9 World, We Need a New Way to Quantify Screen Size

As LG releases its G6 smartphone with an 18:9 screen and other manufacturers adopt this trend of taller displays, diagonal measurements may be a lot less useful: if you compare phones that have different aspect ratios, you would see a considerable difference. This author suggests that screen area is going to be a more sensible way of determining how large a screen is, going forward.

آ…we've become reliant on diagonal measurements of the screen as a way to quantify the size of a deviceآ—4.7- to 5-inchers were small, 5.7 and up was "phablet" territory. But as phones with 18:9 panels start to ship, it's tempting to directly compare the diagonals with their 16:9 forerunners. That can be misleading. Consider the two phones above, the HTC U Ultra and LG G6. Both have 5.7-inch screens, meaning, corner-to-corner, the active portion of the display measures around 5.7 inches (with whatever rounding up or down the manufacturer wants to factor in there.) But it's plain to see in the photo that the U Ultra has a way larger screen, and that's because of the basic geometry of the thingآ—its screen area is bigger.
