Why Test on Apple iPhone 6s?
Viewport
Small viewport stresses spacing and layout consistency.
Pixel Density (DPR)
Retina display exposes blurry images.
Performance & Animations
Aging hardware highlights inefficient rendering.
Viewport Size (CSS Resolution)
The CSS viewport defines how media queries, layout breakpoints, and responsive components behave.
For Apple iPhone 6s, the CSS viewport measures:
- Width: 375 px
- Height: 667 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 6s directly in your browser using Phone Simulator.

Pixel Density (Device Pixel Ratio)
Apple iPhone 6s 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: 750 px
- Height: 1334 px
ℹ️ Physical resolution is not used for CSS layouts but is often shown in analytics tools.
