The wide end of the current matrix
This model provides the upper iPhone reference in the dataset, making it useful for checking media, cards and containers at the large end of phone layouts.
iPhone 16 Pro Max screen size
iPhone 16 Pro Max: 6.9″, 1320 × 2868, 460 PPI, 440 × 956 CSS viewport at DPR 3. It belongs to the widest iPhone layout group in the current dataset and shares that reference with its direct successor, while the same-generation Plus remains in the neighboring group.

Responsive testing plan
iPhone 16 Pro Max responsive workflow
Use the 440 × 956 CSS px at DPR 3 as a real QA target, then pair it with nearby widths for regression testing.
Model-specific checks
- Use this model for the wide end of iPhone coverage, then repeat critical flows in the neighboring large and standard groups.
- Check side-by-side cards, full-bleed media and max-width containers across both large-iPhone groups.
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 Plus is a separate target
Its same-generation Plus companion belongs to the neighboring layout group, so testing only the Pro Max can hide behavior around application breakpoints.
The successor preserves the group
Because the next Pro Max shares this reference viewport, automation can carry forward while named-device screenshots and rendering checks are refreshed.
