iPhone 4S screen size

Screen specs

Safe area insets

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

For web developers

CSS viewport: 320 × 480 CSS pixels in portrait, devicePixelRatio 2. CSS pixels equal points.

/* iPhone 4S, portrait */
@media (device-width: 320px) and (device-height: 480px) 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: 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 2 pixels thick.
• A 44 pt tap target is 88 × 88 pixels.
