Targeting the iPhone 17 Pro Max in CSS
Device-specific media queries are brittle — a new model with the same width will not match. Use them for genuine per-device fixes only, and prefer width buckets for layout.
/* Target iPhone 17 Pro Max specifically */
@media only screen
and (device-width: 440px)
and (device-height: 956px)
and (-webkit-device-pixel-ratio: 3) {
/* … */
}
/* More useful in practice — the width bucket it falls into */
@media (min-width: 440px) { /* … */ }Safe area on the iPhone 17 Pro Max
Dynamic Island, 6.9″ class. Content placed inside the top 62 px or the bottom 34 px will sit under system UI unless you inset it.
/* iPhone 17 Pro Max safe area — requires viewport-fit=cover */
<meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover">
.app {
padding-top: env(safe-area-inset-top); /* 62px */

Questions about the iPhone 17 Pro Max screen
What is the screen size of the iPhone 17 Pro Max?
The iPhone 17 Pro Max has a 6.9-inch display. In CSS the viewport measures 440 × 956 px in portrait, and the panel itself has 1320 × 2868 physical pixels at 460 PPI.
What resolution should I design for on the iPhone 17 Pro Max?
Design at 440 × 956 and export assets at 3×. That gives you 1320 × 2868 px images, which is exactly what the panel renders. Designing directly at 1320 × 2868 means every measurement is 3 times larger than the CSS values you will write.
What is the device pixel ratio of the iPhone 17 Pro Max?
The iPhone 17 Pro Max reports a device pixel ratio of 3. One CSS pixel therefore covers 9 device pixels. You can read it in JavaScript with window.devicePixelRatio.
What are the safe area insets on the iPhone 17 Pro Max?
In portrait the safe area inset is 62 px at the top and 34 px at the bottom (Dynamic Island, 6.9″ class). Use env(safe-area-inset-*) rather than hard-coding these — the values change per device and per orientation.
Which other devices have the same viewport as the iPhone 17 Pro Max?
1 other device shares the 440 × 956 CSS viewport: iPhone 16 Pro Max. A layout that works on one works on all of them.
