Targeting the MacBook Air 13″ (M4) 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.

Questions about the MacBook Air 13″ (M4) screen
What is the screen size of the MacBook Air 13″ (M4)?
The MacBook Air 13″ (M4) has a 13.6-inch display. In CSS the viewport measures 1470 × 956 px in portrait, and the panel itself has 2560 × 1664 physical pixels at 224 PPI.
What resolution should I design for on the MacBook Air 13″ (M4)?
Design at 1470 × 956 and export assets at 2×. That gives you 2560 × 1664 px images, which is exactly what the panel renders. Designing directly at 2560 × 1664 means every measurement is 2 times larger than the CSS values you will write.
What is the device pixel ratio of the MacBook Air 13″ (M4)?
The MacBook Air 13″ (M4) reports a device pixel ratio of 2. One CSS pixel therefore covers 4 device pixels. You can read it in JavaScript with window.devicePixelRatio.
Why does 1470 × 2 not equal 2560?
Because MacBook Air 13″ (M4) ships in a scaled display mode. macOS composites the desktop at 2940 × 1912 — twice the 1470 × 956 logical size — and resamples that frame down to the 2560 × 1664 panel. It is not the panel's native mode; it is the one Apple selects by default because 1470 px of workspace is the more useful number. Design against 1470 × 956 and export at 2×.
Which other devices have the same viewport as the MacBook Air 13″ (M4)?
2 other devices share the 1470 × 956 CSS viewport: MacBook Air 13″ (M3), MacBook Air 13″ (M2). A layout that works on one works on all of them.
