Xiaomi 15 / 14 viewport size

400 × 890CSS px · 3× DPR · 1200×2670 physical

The Xiaomi 15 / 14 gives web pages a 400 × 890 CSS pixel viewport in portrait. That’s the width your layout and media queries actually see, not the 1200 × 2670 physical pixels of the screen: with a device pixel ratio of 3, every CSS pixel is 3 × 3 real pixels.

See your site on a Xiaomi 15 / 14

Paste your address (or localhost:3000). doesitfit shows it at exactly 400 × 890, with Chrome (Android)’s bars if you want them, and tells you if anything spills.

Free, no sign-up. Or ask Claude, ChatGPT or Codex to check it.

What a web page actually sees

The full viewport is 400 × 890, but the browser’s own bars take some of it. In Chrome (Android) a page gets about 400 × 770 on first load (40px status bar, 56px Chrome toolbar and 24px gesture bar on first load). That’s your real “above the fold”. Use 100dvh instead of 100vh for full-height sections, or they’ll hide behind the toolbar (why).

Setting	Width	Height
Full viewport (portrait)	400px	890px
Visible on first load (Chrome (Android))	400px	770px
Landscape (full)	890px	400px

What it means for your CSS

Breakpoints

At 400px: Tailwind uses base styles only (below sm, 640px); Bootstrap uses xs. In landscape (890px): Tailwind uses md (sm: md: styles apply), Bootstrap md.

Tailwind breakpoints on real devices

Content width

With 16px of padding on each side your text column is 368px; with 24px it’s 352px. Text closer than 8px to the edge looks cramped (more).

Sharp images

A full-width image needs about 1200px of real pixels (400 × 3).

<img src="hero-1200.jpg"
  srcset="hero-800.jpg 800w, hero-1200.jpg 1200w"
  sizes="100vw" alt="…">

Styles for this width

Content-first breakpoints beat device lists, but if something breaks at this width:

@media (max-width: 400px) {
  /* screens 400px wide and narrower */
}

Confidence: Estimate: not measured in a browser yet. Android Chrome rounds the CSS size up (ceil of pixels ÷ DPR).
