iPhone SE (3rd 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.

How it was measured: key window safeAreaInsets, portrait and landscape (interface orientation landscapeLeft, rotated with requestGeometryUpdate; landscapeRight identical) (source: Xcode 27.1 Simulator, iOS 27.0 (24A434) runtime, device type 'iPhone SE (3rd generation)').

Corner radius (unofficial)

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

UNOFFICIAL: private UIScreen _displayCornerRadius = 0 pt (source: Xcode 27.1 Simulator, iOS 27.0 (24A434) runtime, device type 'iPhone SE (3rd generation)'); Apple does not publish this value

For web developers

CSS viewport: 375 × 667 CSS pixels in portrait, devicePixelRatio 2. CSS pixels equal points.

/* iPhone SE (3rd generation), portrait */
@media (device-width: 375px) and (device-height: 667px) 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);       /* 20px on iPhone SE (3rd generation) in portrait */
  padding-right: env(safe-area-inset-right);   /* 0px */
  padding-bottom: env(safe-area-inset-bottom); /* 0px */
  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: 375 × 667 points (portrait).
• UIScreen.main.scale: 2.

Same layout size

Same points and scale (375 × 667 pt at @2x):

• iPhone SE (2nd generation)
• iPhone 8
• iPhone 7
• iPhone 6s
• iPhone 6

Compare

• iPhone SE (3rd generation) vs iPhone SE (2nd generation)
