Targeting the iPhone SE (3rd gen) 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 SE (3rd gen) specifically */
@media only screen
and (device-width: 375px)
and (device-height: 667px)
and (-webkit-device-pixel-ratio: 2) {
/* … */
}
/* More useful in practice — the width bucket it falls into */
@media (min-width: 375px) { /* … */ }Safe area on the iPhone SE (3rd gen)
Home button, status bar only. Content placed inside the top 20 px or the bottom 0 px will sit under system UI unless you inset it.
/* iPhone SE (3rd gen) 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); /* 20px */
padding-bottom: env(safe-area-inset-bottom); /* 0px */
padding-left: env(safe-area-inset-left);
padding-right: env(safe-area-inset-right);

Questions about the iPhone SE (3rd gen) screen
What is the screen size of the iPhone SE (3rd gen)?
The iPhone SE (3rd gen) has a 4.7-inch display. In CSS the viewport measures 375 × 667 px in portrait, and the panel itself has 750 × 1334 physical pixels at 326 PPI.
What resolution should I design for on the iPhone SE (3rd gen)?
Design at 375 × 667 and export assets at 2×. That gives you 750 × 1334 px images, which is exactly what the panel renders. Designing directly at 750 × 1334 means every measurement is 2 times larger than the CSS values you will write.
What is the device pixel ratio of the iPhone SE (3rd gen)?
The iPhone SE (3rd gen) reports a device pixel ratio of 2. One CSS pixel therefore covers 4 device pixels. You can read it in JavaScript with window.devicePixelRatio.
What are the safe area insets on the iPhone SE (3rd gen)?
In portrait the safe area inset is 20 px at the top and 0 px at the bottom (Home button, status bar only). 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 SE (3rd gen)?
5 other devices share the 375 × 667 CSS viewport: iPhone SE (2nd gen), iPhone 8, iPhone 7, iPhone 6s, iPhone 6. A layout that works on one works on all of them.
