iPad Pro 12.9-inch (4th generation) screen size

Screen specs

Safe area insets

Outline drawn to scale in points. Shaded bands are the insets; the dashed box is the safe area.

Landscape insets haven't been measured for this device yet.

How it was measured: key window safeAreaInsets, portrait only; full-screen window in the iPadOS 27 default windowing mode, top inset includes the 32 pt status bar (source: Xcode 27.1 Simulator, iOS 27.0 (24A434) runtime, device type 'iPad Pro (12.9-inch) (4th generation)').

Corner radius (unofficial)

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

UNOFFICIAL: private UIScreen _displayCornerRadius = 18 pt (source: Xcode 27.1 Simulator, iOS 27.0 (24A434) runtime, device type 'iPad Pro (12.9-inch) (4th generation)'); Apple does not publish this value

For web developers

CSS viewport: 1024 × 1366 CSS pixels in portrait, devicePixelRatio 2. CSS pixels equal points.

/* iPad Pro 12.9-inch (4th generation), portrait */
@media (device-width: 1024px) and (device-height: 1366px) and (-webkit-device-pixel-ratio: 2) {
  /* styles for this screen size */
}

/* needs <meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover"> */
.page {
  padding-top: env(safe-area-inset-top);       /* 32px on iPad Pro 12.9-inch (4th generation) in portrait */
  padding-right: env(safe-area-inset-right);   /* 0px */
  padding-bottom: env(safe-area-inset-bottom); /* 20px */
  padding-left: env(safe-area-inset-left);     /* 0px */
}

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 2 pixels thick.
• A 44 pt tap target is 88 × 88 pixels.
• Assets: @2x.
• UIScreen.main.bounds: 1024 × 1366 points (portrait).
• UIScreen.main.scale: 2.
