iPhone X includes a large, high-resolution, rounded, edge-to-edge display that delivers an immersive, content-rich experience like never before.
Dimensions: 1125px x 2436px (375pt x 812pt @3x).
When designing for iPhone X, you must ensure that layouts fill the screen and aren’t obscured by the device’s rounded corners, sensor housing, or the indicator for accessing the Home screen.
