Galaxy Tab S9 Ultra screen size & viewport

The Galaxy Tab S9 Ultra renders web pages at a CSS viewport of 960 × 1368 in portrait (1368 × 960 in landscape).

What these numbers mean

960 × 1368 is the CSS viewport size — the coordinate space your layout, media queries and vw/vh units work in. It is not the hardware pixel count: the Galaxy Tab S9 Ultra packs more physical pixels behind each CSS pixel (its device pixel ratio), which is why images meant for it should be exported at 2× or 3×.

For a tablet this size, a layout should already be at its multi-column / tablet breakpoint.

Targeting it in CSS

/* Styles for viewports up to the Galaxy Tab S9 Ultra */
@media (max-width: 960px) {
  .container { padding-inline: 16px; }
}

/* Exactly the Galaxy Tab S9 Ultra in portrait */
@media (width: 960px) and (height: 1368px) { /* … */ }

Common things that break at 960px wide

• Fixed-width elements wider than 928px (content minus typical padding) cause horizontal scroll.
• Tap targets under 44×44 CSS px are hard to hit.
• Sticky headers taller than ~15% of 1368px eat too much of the screen.
• Text set below 16px triggers zoom-on-focus in form fields on iOS.
