Apple states the screen size for the iPhone X as 5.8'' and 5.5'' for the iPhone 8 Plus.
The iPhone X has however round edges and a bit of the screen is cut off at the top for the screen for sensors and the camera.
If you have a look at the really usable screen the size does not seem to be larger than the iPhone 8 Plus.
Additionally, when you hold the iPhone X in your hand you might cover part of the screen with your fingers since it does not have much of a bezel.
Of course the iPhone X does have an OLED display with brighter colors, but that is another issue.
Would you prefer a rectangular screen (as in iPhone 8 Plus) or a screen with round edges screen and with a cavity for sensors and camera?
