More vertical runway at the same width
Text wrapping remains comparable to the earlier compact reference, but feeds, forms and full-height panels can expose different clipping or scroll behavior.
Pixel 9 screen size
Pixel 9: 6.3″, 1080 × 2424, 422 PPI, 412 × 924 CSS viewport at DPR 2.625. This base Pixel preserves the preceding A-series width and density while extending the portrait canvas, providing a focused check for vertical flow and edge-anchored interface elements.

Model-specific guidance
What this means
The Pro is not an equivalent substitute
The same-generation Pro uses a wider CSS reference, so passing there does not prove that navigation labels and fixed-width content fit on the base model.
Viewport facts come from browser tooling
The CSS dimensions are a Chrome emulation reference rather than a manufacturer guarantee and should be validated against target browsers when exact rendering matters.

|---|---|---|---|---|---|
| Pixel 9 Current page | Pixel 9 | 6.3″ | 1080 × 2424 | 412 × 924 | 422 |
| Pixel 8a The earlier A-series model supplies the shorter companion case while holding width and density constant. | Pixel 9 | 6.1″ | 1080 × 2400 | 412 × 915 | 430 |
| Pixel 9 Pro The Pro reveals how the same physical-size class can map to a wider, denser CSS environment. | Pixel 9 | 6.3″ | 1280 × 2856 | 427 × 952 | 495 |

Pixel 9 responsive workflow
Use the 412 × 924 CSS px at DPR 2.625 as a real QA target, then pair it with nearby widths for regression testing.
Model-specific checks
- Compare fixed headers, bottom actions and keyboard-open states with the shorter A-series reference.
- Keep this base model in width-sensitive checks even when the Pro has already passed.
