Apple iPhone 5 - Responsive test in Phone Simulator

The Apple iPhone 5 is a popular device among web developers and designers for testing responsive layouts and mobile UI behavior.

It introduced Apple’s first larger display and a more refined aluminum body, defining a new era of design. Year of release: 2012.

Why Test on Apple iPhone 5?

  • Viewport

    Very small viewport exposes legacy breakpoint and spacing issues.

  • Pixel Density (DPR)

    Lower resolution highlights missing image optimizations.

  • Performance & Animations

    Hardware constraints reveal heavy scripts and layouts.

Viewport Size (CSS Resolution)

The CSS viewport defines how media queries, layout breakpoints, and responsive components behave.

For Apple iPhone 5, the CSS viewport measures:

  • Width: 320 px
  • Height: 568 px

ℹ️ The visible height can vary slightly depending on the browser UI (Safari, Chrome, etc.).

Some analytics platforms only display the physical screen resolution (see below) instead of the CSS viewport size, so keep that in mind when interpreting results.

To see exactly how this viewport behaves in real conditions, you can simulate Apple iPhone 5 directly in your browser using Phone Simulator.

Pixel Density (Device Pixel Ratio)

Apple iPhone 5 has a device pixel ratio of 2.

Each CSS pixel is rendered using 2 physical pixels, resulting in sharper text and images.

For CSS targeting:

css
@media only screen and (-webkit-min-device-pixel-ratio: 2) {
	/* High-DPI specific styles */
}

In JavaScript:

js
window.devicePixelRatio;
// returns: 2

Physical Screen Resolution

Physical resolution refers to the actual number of hardware pixels on the display. While it does not affect CSS layouts, it is commonly shown in analytics and device specifications.

  • Width: 640 px
  • Height: 1136 px

ℹ️ Physical resolution is not used for CSS layouts but is often shown in analytics tools.
