708 × 823CSS px · 2.625× DPR · 1856×2160 physical
The Samsung Galaxy Z Fold 6 — unfolded gives web pages a 708 × 823 CSS pixel viewport in portrait. That’s the width your layout and media queries actually see, not the 1856 × 2160 physical pixels of the screen: with a device pixel ratio of 2.625, every CSS pixel is 2.625 × 2.625 real pixels.

What a web page actually sees
The full viewport is 708 × 823, but the browser’s own bars take some of it. In Chrome (Android) a page gets about 708 × 703 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) | 708px | 823px |
| Visible on first load (Chrome (Android)) | 708px | 703px |
| Landscape (full) | 823px | 708px |

About these numbers
Confidence: Estimate: not measured in a browser yet. 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.
