Galaxy S26 screen size

Galaxy S26: 6.3″, 1080 × 2340, 409 PPI, 360 × 780 CSS viewport at DPR 3. It keeps the same tracked CSS layout target as the previous base Galaxy while changing the physical display, so responsive behavior should remain in the same test group.

Model-specific checks

Use this narrow Android reference for labels, dense forms and fixed-width controls.
Pair it with the wider current Galaxy reference before signing off responsive behavior.

Values marked official come from manufacturer specifications; calculated values are derived from them; reference values are developer layout references and can vary with browser, zoom and operating-system settings.

Model-specific guidance

What this means for layout and testing

The base Galaxy viewport stays familiar

The current reference remains in the narrow Android group already covered by the previous base generation.

Physical change does not imply layout change

Panel size and density can change while the CSS viewport remains stable, which is why responsive tests should follow the layout reference rather than the diagonal alone.

Keep narrow-width pressure tests

This reference is useful for navigation, form and table pressure because it remains narrower than the large Galaxy variants in the dataset.
