Why test your site on Apple iPhone 15 PRO MAX?

Notch and safe areas

On Apple iPhone 15 PRO MAX, the notch and gesture bar reserve part of the screen. Without the env(safe-area-inset-*) variables, your fixed headers and bottom-stuck buttons go under these areas and become unusable.

Large mobile screen

With 430 pixels wide, Apple iPhone 15 PRO MAX already shifts some layouts to their tablet breakpoint. A test prevents overly stretched columns and unreadable text areas.

3x density

Each CSS pixel of Apple iPhone 15 PRO MAX is rendered by 3 physical pixels. Any image, icon, or font provided in simple resolution appears immediately blurry.

CSS viewport resolution of Apple iPhone 15 PRO MAX

This is the width your CSS considers. All your breakpoints and media queries compare to this value, not the number of physical pixels on the panel.

  • 430 pixels in width
  • 932 pixels in height

The height remains indicative: Safari, Chrome, and other mobile browsers reduce the visible area with their address bar, which folds on scroll.

Be cautious when analyzing your statistics: some tools only report the manufacturer resolution, never the CSS viewport presented here.

Pixel density of Apple iPhone 15 PRO MAX

3

The device pixel ratio of Apple iPhone 15 PRO MAX is 3.

Your images should therefore be exported 3 times larger than their display size, otherwise they will appear softened on this screen.

Manufacturer resolution of Apple iPhone 15 PRO MAX

This is the actual number of pixels on the panel. This value does not affect your layouts, but it's the one reported by technical specifications and most analytics tools.

  • 1290 pixels in width
  • 2796 pixels in height
  • 19.5:9 Screen ratio

460 pixels per inch (ppi) · 6.7 inches diagonal, or 17 cm

Notch and safe areas of Apple iPhone 15 PRO MAX

On Apple iPhone 15 PRO MAX, part of the screen is reserved for the notch and gesture bar. Without precaution, a fixed header goes under the notch, and a bottom-stuck button becomes impossible to touch.

Two conditions to remedy this: declare viewport-fit=cover in the meta viewport tag, then use the env(safe-area-inset-*) variables in your padding.

Safe areas

Protects your fixed elements from the notch and gesture bar of Apple iPhone 15 PRO MAX.

.header {
  padding-top: env(safe-area-inset-top);
}

.bottom-bar {
  padding-bottom: env(safe-area-inset-bottom);
}

  /* Apple iPhone 15 PRO MAX */
}

Serves high-resolution images to screens of at least 3x.

@media only screen and (-webkit-min-device-pixel-ratio: 3),
       only screen and (min-resolution: 288dpi) {
  /* High-density images and icons */
}

Tailwind configuration

Adds a named breakpoint at the exact width of Apple iPhone 15 PRO MAX.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'apple-iphone-15-pro-max-2023': '430px'
    }
  }
}

JavaScript detection

Detects format and density client-side.

const isDeviceWidth = window.matchMedia('(min-width: 430px)').matches;
const isHighDensity = window.devicePixelRatio >= 3;

Meta viewport tag

Essential for Apple iPhone 15 PRO MAX to use its CSS viewport and not a simulated width of 980 pixels.

<meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover">
