Apple iPhone 15: CSS viewport of 393 × 852 px, resolution and responsive test

Why test your site on Apple iPhone 15?

CSS viewport resolution of Apple iPhone 15

This is the resolution that interests designers and developers the most, as it determines breakpoints and the definition of media queries. In practice, it's the only one mentioned in a stylesheet.

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

The device pixel ratio of Apple iPhone 15 is 3. In other words, a 1-pixel square in CSS occupies 3 pixels on the panel. An image exported at actual size will appear blurry.

Manufacturer resolution of Apple iPhone 15

This resolution is the hardware's. It explains the display's sharpness, but it's never the one to target in a media query.

• 1179 pixels in width
• 2556 pixels in height
• 461 pixels per inch (ppi)
• 6.1 inches diagonal, or 15.5 cm
• Screen ratio of 19.5:9

User-Agent of Apple iPhone 15

This string is what the browser of Apple iPhone 15 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

On Apple iPhone 15, 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);
}

Media queries and code snippets for Apple iPhone 15

These snippets are generated from the exact characteristics of Apple iPhone 15. Copy them directly into your stylesheet or configuration.

@media only screen and (min-width: 393px) and (max-width: 851px) {
  /* Apple iPhone 15 */
}

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

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'apple-iphone-15-2023': '393px'
    }
  }
}

const isDeviceWidth = window.matchMedia('(min-width: 393px)').matches;
const isHighDensity = window.devicePixelRatio >= 3;

Mobile FIRST includes Apple iPhone 15: your page displays in a viewport of 393 x 852 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 — Select Apple iPhone 15 from the list of devices. The viewport switches to 393 x 852 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

These 2 devices share exactly the viewport of 393 x 852 pixels and the 3x density of Apple iPhone 15. Their CSS rendering is therefore exactly the same: what you validate on one is valid on all others.
