iPhone Screen Comparison

iPhone 16 Pro vs iPhone 15 Pro Screen Size

The iPhone 16 Pro gives you a modestly larger canvas while keeping the same stated 460 ppi density. The difference is visible, but it is an incremental size change rather than a jump to a Max-size phone.

TV Screen Size Comparison

65-inch vs 75-inch TV Size Comparison

A 75-inch TV is not just 10 inches wider than a 65-inch TV—the numbers are diagonals. At the same 16:9 ratio, the 75-inch screen adds meaningful width, height, and screen area.

Monitor Screen Size Comparison

27-inch vs 32-inch Monitor Size Comparison

The 32-inch monitor delivers a larger physical canvas and, in this representative 4K configuration, a higher pixel density. The 27-inch QHD option is easier to fit on a typical desk.

MacBook Screen Comparison

13-inch vs 15-inch MacBook Air Screen Size

The 15-inch MacBook Air provides a clearly larger workspace at the same stated 224 ppi. The 13-inch model is the more compact choice when portability matters most.

iPad Screen Comparison

11-inch vs 13-inch iPad Pro Screen Size

The 13-inch iPad Pro gives you a materially larger drawing and multitasking canvas. The 11-inch model preserves the same stated 264 ppi in a more portable footprint.

Steam Deck OLED vs Nintendo Switch OLED Screen Size

The Steam Deck OLED screen is larger and taller in shape because it uses 16:10 rather than 16:9. The Switch OLED display is slightly smaller and wider proportionally.

How it works

Diagonal is only the beginning.

Use known physical dimensions directly, or combine diagonal length with aspect ratio to derive width, height, and area using transparent geometry.

    Compare width, height, area, aspect ratio, and orientation at one proportional scale.

FAQ

Screen-size questions, answered

The essential definitions and assumptions behind an accurate screen comparison.

What is screen size?
Screen size is usually the diagonal length of the active display, measured from one corner to the opposite corner. It does not include the bezel or full device body.
How do I compare two screen sizes accurately?
Enter the active display width and height directly, or use diagonal and aspect ratio to calculate them. Then compare resolution and PPI separately because pixels and physical size describe different things.
Why is screen area more useful than diagonal?
Diagonal is a one-dimensional length. Area captures both width and height, so it better expresses how much additional viewing surface a larger display provides.
Does bezel size count as screen size?
No. Bezel belongs to the product body. Screen comparisons use the active display area; full product dimensions are needed for wall, desk, bag, or pocket fit.
What is aspect ratio?
Aspect ratio describes the relationship between a screen’s long and short sides, such as 16:9 or 4:3. It determines the shape of a display and changes width and height at a given diagonal.
What is PPI?
PPI means pixels per inch. It describes how densely the native pixel grid is packed into the physical screen and is calculated from resolution and diagonal.
Are the visual comparisons life-size?
The two outlines are shown at the same proportional scale, so their relative difference is accurate. Your browser display is not physically calibrated, so use the listed measurements for exact planning.
Where do device specifications come from?
Named-device records use linked first-party manufacturer specifications where available. Derived values such as physical width, area, or calculated PPI are labeled and explained in the methodology.
