Apple iPhone 15 PRO MAX: CSS viewport of 430 × 932 px, resolution and responsive test

Why test your site on Apple iPhone 15 PRO MAX?

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.

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

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
• 460 pixels per inch (ppi)
• 6.7 inches diagonal, or 17 cm
• Screen ratio of 19.5:9

User-Agent of Apple iPhone 15 PRO MAX

This string is what the browser of Apple iPhone 15 PRO MAX sends. It is useful for your automated tests, reading your server logs, and server-side detection.

Mozilla/5.0 (iPhone; CPU iPhone OS 26_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/26.0 Mobile/15E148 Safari/604.1

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.

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

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

Mobile FIRST includes Apple iPhone 15 PRO MAX: your page displays in a viewport of 430 x 932 pixels, with the model's User-Agent, touch events, and scrolling behavior of a real mobile.

This is where the difference with Chrome DevTools' responsive mode is seen: DevTools resizes a window, the extension replicates the device's browser and allows exporting shareable screenshots and videos.

1. 01 Install the extension — Add Mobile FIRST to Chrome, Firefox, or Edge. Installation is free and requires no account.
2. 02 Open the page to test — Go to the URL to check, including a local address like localhost:3000.
3. 03 Choose Apple iPhone 15 PRO MAX — Select Apple iPhone 15 PRO MAX from the list of devices. The viewport switches to 430 x 932 pixels, and the mobile User-Agent is applied.
4. 04 Check rendering — Scroll, change orientation, test your forms, then capture an image or video to share.

Models sharing the format of Apple iPhone 15 PRO MAX

These 2 devices share exactly the viewport of 430 x 932 pixels and the 3x density of Apple iPhone 15 PRO MAX. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.
