iPhone 14 Pro viewport size

393 × 852CSS px · 3× DPR · 1179×2556 physical

The iPhone 14 Pro gives web pages a 393 × 852 CSS pixel viewport in portrait. That’s the width your layout and media queries actually see, not the 1179 × 2556 physical pixels of the screen: with a device pixel ratio of 3, every CSS pixel is 3 × 3 real pixels.

See your site on an iPhone 14 Pro

Paste your address (or localhost:3000). doesitfit shows it at exactly 393 × 852, with Safari (iOS 26)’s bars if you want them, and tells you if anything spills.

What a web page actually sees

The full viewport is 393 × 852, but the browser’s own bars take some of it. In Safari (iOS 26) a page gets about 393 × 699 on first load (59px status bar and Safari’s 94px bottom tab bar on first load; the bars shrink when you scroll). 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)	393px	852px
Visible on first load (Safari (iOS 26))	393px	699px
Landscape (full)	852px	393px

What it means for your CSS

Breakpoints

At 393px: Tailwind uses base styles only (below sm, 640px); Bootstrap uses xs. In landscape (852px): 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 361px; with 24px it’s 345px. Text closer than 8px to the edge looks cramped (more).

Sharp images

A full-width image needs about 1179px of real pixels (393 × 3).

<img src="hero-1179.jpg"
  srcset="hero-800.jpg 800w, hero-1179.jpg 1179w"
  sizes="100vw" alt="…">

Styles for this width

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

@media (max-width: 393px) {
  /* screens 393px wide and narrower */
}
