iPhone XS Max viewport size

iPhone XS Max (2018) lays web pages out at 414 × 896 CSS pixels with a pixel ratio of 3.

Browser bars and the visible area

The viewport height is the whole screen, but Safari on iOS keeps part of it for its own interface. In portrait about 47 px at the top (status bar and notch area) and 130 px at the bottom (Safari's address bar and toolbar) are covered, leaving roughly 414 × 719 CSS px for the page when it first opens. In landscape the bars take about 50 px.

That is why 100vh can be taller than what people see. Use 100svh for the smallest visible height, 100dvh for the current one, and keep the most important content and buttons within the first 719 px.

Media queries that match the iPhone XS Max

/* iPhone XS Max, portrait */
@media (max-width: 414px) and (orientation: portrait) { … }

/* high-density screen (3×) */
@media (min-resolution: 3dppx) { … }

Rather than targeting one device, write fluid styles and add breakpoints where your layout needs them — the same CSS then works on the 5 other devices with the same width and hundreds of models with similar sizes.

Testing on the iPhone XS Max

Apple devices render with WebKit, the engine behind Safari. Chrome's device toolbar only resizes Chromium, so fonts, form controls and toolbar behaviour can differ from a real iPhone. MobileCheck renders iPhones with WebKit — see how to test a website on an iPhone.

The iPhone XS Max is one of the 51 devices in the free check, and you can tap around your site on it in the phone window.
