A Pro Max boundary between generations
The following Pro Max belongs to a wider reference group, so retaining both targets catches a layout transition that the product name alone does not reveal.
iPhone 15 Pro Max screen size
iPhone 15 Pro Max: 6.7″, 1290 × 2796, 460 PPI, 430 × 932 CSS viewport at DPR 3. It is the last tracked Pro Max in an earlier large-iPhone layout group; its direct successor moves wider, while iPhone 16 Plus keeps this reference available in the next generation.

Model-specific guidance
What this means
The layout group continues on Plus
The next-generation Plus model shares this primary reference, allowing viewport automation to carry forward across a different product tier.
Large-screen success is not range coverage
This roomy target can hide wrapping and fixed-width failures that remain visible on standard and compact iPhone references.

Model-specific checks
- Keep the next Pro Max target beside this one when checking wide cards, galleries and modal proportions.
- Reuse this viewport group for iPhone 16 Plus automation, but preserve separate visual baselines for release QA.
