Why Test on Apple iPhone 5s?
Viewport
Compact viewport stresses navigation and text sizing.
Pixel Density (DPR)
Standard pixel density reveals blurry images and icon scaling issues on screen.
Performance & Animations
Limited performance exposes inefficient code.
Viewport Size (CSS Resolution)
The CSS viewport defines how media queries, layout breakpoints, and responsive components behave.
For Apple iPhone 5s, 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.
To see exactly how this viewport behaves in real conditions, you can simulate Apple iPhone 5s directly in your browser using Phone Simulator.

Pixel Density (Device Pixel Ratio)
Apple iPhone 5s 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:
@media only screen and (-webkit-min-device-pixel-ratio: 2) {
/* High-DPI specific styles */
}In JavaScript:
window.devicePixelRatio;
// returns: 2Physical 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.
