iPhone 15 Pro Max / 15 Plus viewport size
430 × 932CSS px · 3× DPR · 1290×2796 physical
The iPhone 15 Pro Max / 15 Plus gives web pages a 430 × 932 CSS pixel viewport in portrait. That’s the width your layout and media queries actually see, not the 1290 × 2796 physical pixels of the screen: with a device pixel ratio of 3, every CSS pixel is 3 × 3 real pixels.

Paste your address (or localhost:3000). doesitfit shows it at exactly 430 × 932, 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 430 × 932, but the browser’s own bars take some of it. In Safari (iOS 26) a page gets about 430 × 779 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) | 430px | 932px |
| Visible on first load (Safari (iOS 26)) | 430px | 779px |
| Landscape (full) | 932px | 430px |
What it means for your CSS
Breakpoints
At 430px: Tailwind uses base styles only (below sm, 640px); Bootstrap uses xs. In landscape (932px): Tailwind uses md (sm: md: styles apply), Bootstrap md.
Content width
With 16px of padding on each side your text column is 398px; with 24px it’s 382px. Text closer than 8px to the edge looks cramped (more).
Sharp images
A full-width image needs about 1290px of real pixels (430 × 3).
<img src="hero-1290.jpg" srcset="hero-800.jpg 800w, hero-1290.jpg 1290w" sizes="100vw" alt="…">
Styles for this width
Content-first breakpoints beat device lists, but if something breaks at this width:
@media (max-width: 430px) {
/* screens 430px wide and narrower */
}Other display size settings
The scaling the owner picks changes the viewport your site gets:
