iPad Pro 13" (M4): 13″, 2064 × 2752, 264 PPI, 1032 × 1376 CSS viewport at DPR 2. The larger M4 Pro enlarges an entire document page relative to the smaller Pro. Its less elongated panel also means that a landscape widescreen picture gains less area than the screen itself does.
The smaller Pro is closer to a widescreen shape. Moving to this model increases the complete picture size but also the share left outside it. The panel-area gain overstates the video-area gain; diagonal length is a different measure.
A complete A4 page fitted in portrait grows by a different area proportion from landscape video. Its width relative to paper can also be calculated; reader toolbars and split view would reduce the available rectangle.
Worked example · calculated geometry
Compared with iPad Pro 11" (M4), iPad Pro 13" (M4) adds about 29.5% to a complete landscape video picture and 36.3% to a complete portrait A4 page. Both percentages compare area; the panel itself grows by 40.9%.
Unused panel area: 18.4% on iPad Pro 11" (M4), 25% on iPad Pro 13" (M4).
Adjust this video comparison →Relative to physical paper, page width and height are 76.2% on iPad Pro 11" (M4) and 88.9% on iPad Pro 13" (M4). These are linear scales, separate from the area increases above.
Adjust this document comparison →Fit the complete image inside each display rectangle using the smaller width or height scale. Video uses 16:9; A4 uses 210:297. Area change is (subject area ÷ baseline area − 1) × 100. Rounded corners, reader or player controls and split view are excluded. This geometry does not establish reading comfort.
Diagrams share a proportional scale within each comparison. Their displayed size is not calibrated to physical inches on your screen.
These are the dates of the recorded fact checks. A hardware specification source does not establish a browser viewport. Calculations and illustration assumptions are described above; no new device measurements are claimed.
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 Pro 13" (M4) Current page | iPad Pro 13" (M4) | 13″ | 2064 × 2752 | 1032 × 1376 | 264 |
| iPad Pro 11" (M4) The smaller M4 Pro uses a larger fraction of its panel for widescreen video, but shows a smaller absolute picture. | iPad Pro 13" (M4) | 11.1″ | 1668 × 2420 | 834 × 1210 | 264 |
| iPad Air 11" (M2) The Air supplies a materially smaller full-screen reference and is a better boundary for layouts that should remain tablet-oriented. | iPad Pro 13" (M4) | 10.9″ | 1640 × 2360 | 820 × 1180 | 264 |
| iPad mini (A17 Pro) The mini is the compact end of the iPad range and exposes assumptions hidden by this expansive canvas. | iPad Pro 13" (M4) | 8.3″ | 1488 × 2266 | 744 × 1133 | 326 |

/* Test immediately below and above your layout breakpoints. */Use the 1032 × 1376 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.
