Screen Size Comparison
See how much larger one display is, and how a complete video or A4 document fits. Compare known models, custom sizes or your calibrated screen.
Choose displays, then switch between display outlines, a complete 16:9 picture and an A4 page

Choose a known display or enter a custom size to see the comparison.
Outlines represent the display rectangle, excluding the device body. Calculations use the stated diagonal and screen proportions. Rounded corners, cutouts and app controls are excluded.
A larger screen does not give the same increase in video area
Compare iPad Pro 11" (M4) with iPad Pro 13" (M4). The larger model has 40.9% more display area, but the same complete 16:9 picture occupies 29.5% more area. Their different screen shapes account for the difference.
| Display | Screen width × height | Screen area | 16:9 picture width × height | Picture area |
|---|---|---|---|---|
| iPad Pro 11" (M4) | 9.14″ × 6.3″ | 57.57 in² | 9.14″ × 5.14″ | 46.98 in² |
| iPad Pro 13" (M4) | 10.4″ × 7.8″ | 81.12 in² | 10.4″ × 5.85″ | 60.84 in² |
How this example is calculated
Screen width and height come from the recorded diagonal and the ratio of the panel's pixel dimensions. For a full 16:9 picture, the fit scale is the smaller of screen width ÷ 16 and screen height ÷ 9. Picture width is 16 × scale; height is 9 × scale. The unused area appears as black bars.
This is a geometric illustration of the listed models, not an app screenshot or a current-generation buying recommendation. It excludes rounded corners, cutouts and playback controls. The diagrams use a common proportional scale; physical sizing on your display requires calibration.
How large is an A4 page on a tablet?
The same complete page appears at 76.2% of paper size on iPad Pro 11" (M4)and 88.9% on iPad Pro 13" (M4). These percentages describe linear dimensions, not area: a page at half scale has half the printed width and height.
Page: 160 × 226.3 mm · 76.2% scale
Unused display: 2.5%
Page: 186.8 × 264.2 mm · 88.9% scale
Unused display: 5.7%
A4 is 210 × 297 mm. Fit the entire page inside the portrait display using the smaller of display width ÷ paper width and display height ÷ paper height, with both in the same units. The display dimensions use the sourced model records listed in the video example above. Reader toolbars, margins added by apps and split view would reduce the available space. This illustration does not establish whether text is comfortable to read.
Open this document comparison →Why diagonal inches mislead
Screen sizes are quoted as diagonals, but what you actually see is area — and area depends on the aspect ratio too. A 6.9″ phone at 19.5:9 is narrower than a 6.5″ phone at 16:9 would be. That's why the visual comparison above matters more than the spec-sheet number. For the underlying figures, see thephone screen size chart.
Frequently asked questions
›What does A4 full-page scale mean?
It compares the physical width and height of a complete page on the display with A4 paper. A scale of 80% means each edge is four-fifths of its printed length. Reader toolbars and app margins are excluded; the result does not predict reading comfort.
›How do I compare two phone screen sizes?
Search for both phones above and they'll be drawn as proportional outlines, overlaid or side by side. The table below the diagram shows the diagonal, width × height, area, and the percentage difference in screen area.
›What does true-size mode do?
After you match a standard card or enter a known display diagonal, true-size mode uses that calibration to estimate physical size on this screen. Recheck after changing display or zoom. Larger objects can extend beyond the window; scroll to inspect them. The outlines show display rectangles, excluding device bodies.
›Is a 6.7-inch phone much bigger than a 6.1-inch one?
More than the numbers suggest: diagonal grows linearly but area grows roughly with its square. A 6.7-inch phone of the same ratio has about 20% more screen area than a 6.1-inch one. Try both sizes above to see it.
›Can I compare a phone with my own screen?
Yes. Click 'Add your screen' and calibrate this display. Before calibration, its inches, physical outline and area comparisons remain unavailable. In a shared link, 'your screen' refers to whoever opens the link; their result may differ.
›Why does a larger screen not always give proportionally more video area?
The complete video picture must fit inside the screen. When the video and screen have different aspect ratios, some area is unused. Choose the 16:9 video view to compare the actual picture rectangle and black bars, then change direction to see the effect of portrait and landscape.
