Apple iPhone 13 PRO: CSS viewport of 390 × 844 px, resolution and responsive test

Why test your site on Apple iPhone 13 PRO?

CSS viewport resolution of Apple iPhone 13 PRO

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 13 PRO

The device pixel ratio of Apple iPhone 13 PRO is 3. Your images should therefore be exported 3 times larger than their display size, otherwise they will appear softened on this screen.

Mobile FIRST includes Apple iPhone 13 PRO: 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 13 PRO — Select Apple iPhone 13 PRO 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.
