iPhone XS Max screen size

Screen specs

Safe area insets

Safe areas haven't been measured for this device yet.

Corner radius (unofficial)

39 pt (unofficial). Apple doesn't publish this; measured from the Simulator's private display corner radius.

UNOFFICIAL: DeviceCornerRadius key in the Simulator device type (source: Xcode 27.1 Simulator device type 'iPhone Xs Max', iPhone Xs Max.simdevicetype capabilities.plist (static, not booted)); on the booted iOS 27 device types this key matched the private UIScreen _displayCornerRadius to within 0.34 pt (it differs only for the iPhone 12 family: 47/53 vs 47.33/53.33). Apple does not publish this value

For web developers

CSS viewport: 414 × 896 CSS pixels in portrait, devicePixelRatio 3. CSS pixels equal points.

/* iPhone XS Max, portrait */
@media (device-width: 414px) and (device-height: 896px) and (-webkit-device-pixel-ratio: 3) {
  /* styles for this screen size */
}

/* needs <meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover"> */
.page { padding: env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left); }
/* this device's insets aren't measured yet */

Safari's visible viewport is smaller than the screen because of the browser bars, so window.innerHeight is less than the height above until the bars collapse.

For iOS developers

• A 1 pt line is 3 pixels thick.
• A 44 pt tap target is 132 × 132 pixels.
• Assets: @3x.
• UIScreen.main.bounds: 414 × 896 points (portrait).
• UIScreen.main.scale: 3.
