Apple iPhone 6 – Viewport, Resolution & Specs

Apple iPhone 6 - Test in Phone Simulator

The Apple iPhone 6 is one of the most popular modern smartphones for web designers and front-end developers to test responsive layouts.

If you want to check how your website looks and behaves on this device, you can easily simulate it using the Phone Simulator – Mobile Emulator Tool Chrome extension — no real device required.

Viewport Size (CSS Resolution)

This is the resolution that matters most to designers and developers — it defines media query breakpoints, layout scaling, and how elements adapt to the screen.

For the Apple iPhone 6, the CSS viewport measures:

  • Width: 375 px
  • Height: 667 px*

ℹ️ Note: 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.

Pixel Density (Device Pixel Ratio)

The Apple iPhone 6 has a device pixel ratio of 2 — meaning each CSS pixel is represented by three physical pixels.

This ensures sharper visuals, crisper text, and smoother icons on high-resolution displays.

For CSS targeting:

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

In JavaScript:

window.devicePixelRatio 
// returns: 2

Physical Screen Resolution

Based on its pixel density, the manufacturer’s screen resolution equals:

  • Width: 750 px
  • Height: 1334 px
The Apple iPhone 6 provides a large, high-definition display ideal for testing responsive layouts, images, and typography.
