iPhone Screen Size Comparison

Compare iPhone displays by visible size, shape, resolution, and pixel density—not by diagonal alone.

01

Screen size is the diagonal of the display area, measured from corner to opposite corner.

02

Two iPhones with a similar diagonal can have different widths, heights, and usable areas.

03

Resolution counts pixels; PPI describes how tightly those pixels are packed.

04

Cases and bezels affect overall device size but do not increase the screen diagonal.

Overview

What this comparison tells you

An iPhone screen-size comparison is most useful when it separates the marketed diagonal from the space you can actually see and use. Choose two displays to compare their physical proportions, portrait and landscape footprint, screen area, resolution, and pixel density at the same scale.

Short answer

Compare iPhone displays by visible size, shape, resolution, and pixel density—not by diagonal alone. Use the proportional visual for shape, then use the table for precise entered or calculated measurements.

Decision guide

Advantages & tradeoffs

Advantages

  • A consistent device family makes same-scale visual comparisons easy to understand.
  • High pixel density keeps text and interface details crisp at phone viewing distances.
  • Multiple size classes let buyers balance pocketability against visible workspace.

Tradeoffs

  • A larger diagonal usually increases device footprint and reach distance.
  • Rounded corners and display cutouts can reduce usable rectangular area.
  • A similar marketed diagonal does not guarantee identical width or content space.

Definitions

How the measurements work

Diagonal
The corner-to-corner active-display measurement. It does not include the bezel.
Width & height
Entered directly or calculated from diagonal and aspect ratio using the Pythagorean theorem.
Screen area
Physical width multiplied by height. It often communicates “how much bigger” better than diagonal.
Pixel density
Resolution diagonal divided by physical diagonal, expressed in pixels per inch (PPI).

FAQ

iPhone Screen Size Comparison: questions & answers

20 practical answers about iphone screen size comparison, measurements, fit, and image quality.

How is an iPhone screen size measured?
Measure the visible display diagonally from one corner to the opposite corner, excluding the bezel. Official diagonal figures may describe the full rounded rectangle, so the viewable area can be slightly smaller.
Why can two iPhones with the same screen size feel different?
Aspect ratio, corner radius, bezel width, display cutouts, and body shape all affect how a screen feels. Diagonal size is only one dimension and does not fully describe width, height, or usable area.
Does the iPhone bezel count as screen size?
No. Screen size refers to the display itself. The bezel belongs to the device body and matters when comparing overall dimensions, pocket fit, or reach, but it is not part of the display diagonal.
How should I compare iPhone screens in landscape mode?
Rotate both comparison outlines and compare their physical width, height, and aspect ratio. Landscape can expose width differences that are less obvious when two tall displays are shown in portrait.
What does PPI mean on an iPhone display?
PPI means pixels per inch. It is calculated from pixel resolution and physical diagonal, and it indicates pixel density rather than screen size. A higher PPI packs more pixels into each inch.
Is resolution the same as iPhone screen size?
No. Resolution is the number of addressable pixels, while screen size is a physical measurement. Two displays can have similar dimensions but different resolutions, or the same resolution at different physical sizes.
Does Display Zoom change an iPhone's physical screen size?
No. Display Zoom changes the apparent scale of interface elements. It does not change the display diagonal, physical area, native panel resolution, or device dimensions.
Does an iPhone case affect the screen-size comparison?
A case does not change the screen, but it increases overall width, height, and thickness. Compare bare-device dimensions first, then add the case measurements if pocket or holder fit matters.
How do I choose between compact and large iPhone screens?
Compare hand reach, text size at your preferred settings, typing comfort, media area, and pocket fit. A true-to-scale outline is more informative than choosing from diagonal numbers alone.
What is the fairest way to compare iPhone display area?
Use physical width multiplied by physical height, with adjustments for the actual display shape when data is available. For displays with the same aspect ratio, area grows with the square of the diagonal.
What does diagonal size mean for iPhone Screen Size?
Diagonal is the straight-line distance between opposite corners of the active display. Width, height, aspect ratio, and area are also needed to understand the complete iphone screen size.
Does aspect ratio change iphone screen size comparisons?
Yes. At the same diagonal, a wider aspect ratio produces a wider, shorter screen, while a squarer ratio produces more height. Compare by entering active width and height directly, or by using diagonal and aspect ratio together.
How is screen area calculated for iphone screen size?
Screen area is physical width multiplied by height. The tool uses entered active-display dimensions directly, or derives width and height from diagonal and aspect ratio before multiplying them. Published manufacturer area is kept separate from unsourced user input.
Is higher PPI always better when comparing iphone screen size?
Not automatically. Higher PPI means pixels are packed more densely, but viewing distance, resolution scaling, panel quality, brightness, and the intended use also affect perceived clarity.
How do resolution and physical size differ for iphone screen size?
Resolution counts the pixel grid; physical size measures the screen in inches or centimetres. A larger screen can have the same resolution and therefore lower PPI, while a smaller screen can pack the same pixels more tightly.
Do iphone screen size measurements include the bezel or device body?
No. The advertised screen diagonal normally covers the active panel, not the surrounding frame. Check full product dimensions separately when fit, mounting, or pocket space matters.
Why compare iphone screen size in portrait and landscape?
Rotation does not change physical area, but it changes how width and height relate to reading, video, gaming, drawing, and workspace layouts. The rotate control makes both orientations easy to inspect.
Is the on-screen visualization life-size?
It is proportionally accurate between the two selected screens, but it is not calibrated to your monitor’s physical scale. Use the listed measurements or a reference object for real-world planning.
Why can published dimensions differ slightly from calculated dimensions?
Manufacturers may round the diagonal, measure a standard rectangle behind rounded corners, or use nominal size classes. We preserve the source value and show calculations to sensible precision rather than implying false exactness.
Which iphone screen size class should I compare first?
Start with compact phone class and standard phone class, then compare the exact models you are considering. Use case, viewing distance, fit, and density matter more than a single universal “best” size.
