Apple iPhone 13 - Preview in browser

The Apple iPhone 13 is a popular device among web developers and designers for testing responsive layouts and mobile UI behavior.

It continues Apple’s legacy of performance and durability, setting a standard for mobile design. Year of release: 2021.

Why Test on Apple iPhone 13?

  • Viewport

    iPhone 13 uses a modern mobile viewport that exposes breakpoint, spacing, and navigation issues.

  • Pixel Density (DPR)

    High pixel density makes blurry images and scaling issues immediately visible.

  • Performance & Animations

    Smooth scrolling and animations are expected — performance issues quickly stand out.

Viewport Size (CSS Resolution)

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

For Apple iPhone 13, the CSS viewport measures:

  • Width: 390 px
  • Height: 844 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 13 directly in your browser using Phone Simulator.

Pixel Density (Device Pixel Ratio)

Apple iPhone 13 has a device pixel ratio of 3.

Each CSS pixel is rendered using 3 physical pixels, resulting in sharper text and images.

For CSS targeting:

css
@media only screen and (-webkit-min-device-pixel-ratio: 3) {
	/* High-DPI specific styles */
}

In JavaScript:

js
window.devicePixelRatio;
// returns: 3

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: 1170 px
  • Height: 2532 px

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