Apple iPhone 14: CSS viewport of 390 × 844 px, resolution and responsive test

Why test your site on Apple iPhone 14?

CSS viewport resolution of Apple iPhone 14

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 14

The device pixel ratio of Apple iPhone 14 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.

• 2532 pixels in height
• 457 pixels per inch (ppi)
• 6.1 inches diagonal, or 15.5 cm
• Screen ratio of 19.5:9

Mobile FIRST includes Apple iPhone 14: your page displays in a viewport of 390 x 844 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 14 — Select Apple iPhone 14 from the list of devices. The viewport switches to 390 x 844 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.
