iPhone Air screen size

iPhone Air: 6.5″, 1260 × 2736, 460 PPI, 420 × 912 CSS viewport at DPR 3. It occupies a layout group of its own in the current dataset, so supporting it requires an explicit test target rather than reusing a neighboring iPhone reference.

Model-specific checks

Add this model as an explicit matrix row when Air coverage matters, bracketed by its nearest narrower and wider references.
Do not assume an existing Pro-family target covers this layout group; verify it directly.

Values marked official come from manufacturer specifications; calculated values are derived from them; reference values are developer layout references and can vary with browser, zoom and operating-system settings.

Model-specific guidance

What this means for layout and testing

A singleton in the iPhone range

No other tracked iPhone shares its reference viewport, so regression suites built only around established groups will not cover it implicitly.

Bounded by familiar neighbors

The current base model supplies the nearest narrower reference, while the preceding Plus supplies the nearest wider one for boundary testing.

Singleton widths surface edge cases

A width nobody shares is where max-width containers, fixed rails and tuned gutters that silently depend on established group boundaries tend to break.
