Shared geometry removes duplicate breakpoint work
Because the base model and Air resolve to the same full-screen CSS canvas, teams can use one responsive target while deciding separately which physical devices need release checks.
iPad (10th gen): 10.9″, 1640 × 2360, 264 PPI, 820 × 1180 CSS viewport at DPR 2. This base iPad shares its complete tracked screen profile with the newer Air, so its value is compatibility coverage for that device generation rather than an additional layout width.

Moving to the mini reduces available CSS width and changes density, creating a more meaningful test for tablet navigation, card grids and reading layouts.
The specifications below come from the device records; the notes explain why each comparison is useful.
| Device configuration | Matched to | Screen | Panel | Viewport / workspace | PPI |
|---|---|---|---|---|---|
| iPad (10th gen) Current page | iPad (10th gen) | 10.9″ | 1640 × 2360 | 820 × 1180 | 264 |
| iPad Air 11" (M2) The Air has an identical tracked screen profile, so differences between the pages reflect model identity rather than responsive geometry. | iPad (10th gen) | 10.9″ | 1640 × 2360 | 820 × 1180 | 264 |
| iPad mini (A17 Pro) The mini is the relevant lower-width tablet boundary and adds a denser asset environment. | iPad (10th gen) | 8.3″ | 1488 × 2266 | 744 × 1133 | 326 |
/* iPad (10th gen) — portrait reference, not a breakpoint */
viewport: 820 × 1180 CSS px
panel: 1640 × 2360 · DPR 2
/* Test immediately below and above your layout breakpoints. */Use the 820 × 1180 CSS px at DPR 2 as a real QA target, then pair it with nearby widths for regression testing.
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.
