Samsung Galaxy Tab S11 / S9 (11″) viewport size
800 × 1280CSS px · 2× DPR · 1600×2560 physical
The Samsung Galaxy Tab S11 / S9 (11″) gives web pages a 800 × 1280 CSS pixel viewport in portrait. That’s the width your layout and media queries actually see, not the 1600 × 2560 physical pixels of the screen: with a device pixel ratio of 2, every CSS pixel is 2 × 2 real pixels.

What a web page actually sees
The full viewport is 800 × 1280, but the browser’s own bars take some of it. In Chrome (Android tablet) a page gets about 800 × 1168 on first load (24px status bar, 56px Chrome toolbar and 32px 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) | 800px | 1280px |
| Visible on first load (Chrome (Android tablet)) | 800px | 1168px |
| Landscape (full) | 1280px | 800px |
What it means for your CSS
Breakpoints
At 800px: Tailwind uses md (sm: md: styles apply); Bootstrap uses md. In landscape (1280px): Tailwind uses xl (sm: md: lg: xl: styles apply), Bootstrap xl.
Content width
With 16px of padding on each side your text column is 768px; with 24px it’s 752px. Text closer than 8px to the edge looks cramped (more).
Sharp images
A full-width image needs about 1600px of real pixels (800 × 2).
<img src="hero-1600.jpg" srcset="hero-800.jpg 800w, hero-1600.jpg 1600w" sizes="100vw" alt="…">
Styles for this width
Content-first breakpoints beat device lists, but if something breaks at this width:
@media (max-width: 800px) {
/* screens 800px wide and narrower */

About these numbers
Confidence: Good: from official specs and reports. Samsung phones default to a 384px-wide layout on Plus/Ultra/FE/A-series and 360px on the base S-series; about a third of users change "Display size", so those settings are selectable in the toolbar. Android Chrome rounds the CSS size up (ceil of pixels ÷ DPR). Samsung tablet DPRs are disputed between sources; treat them as likely rather than confirmed.
