iPhone 15 Plus sourced display reference
Use this reviewed phone record for large-screen iPhone wrapping and reachability. Hardware specifications and representative browser-testing values are kept separate so the page does not imply that a static CSS profile is a measured device state.
Reference scope: iPhone 15 Plus (2023) display record. Check the generation and display option before using the profile; other sizes and modes are outside this page.
Two measurement layers
The native display values come from Apple. CSS dimensions are a normalized testing baseline and remain dependent on browser state.
| Field | Reference value | Evidence scope |
|---|---|---|
| Display diagonal | 6.7 inches | Apple manufacturer specification; rounded corners or display shape can reduce viewable area. |
| Native pixel grid | 1290 × 2796 | Apple manufacturer specification in portrait or logical display order. |
| Pixel density | 460 PPI | Apple stated or specification-derived hardware density. |
| CSS viewport | 430 × 932 CSS px | Representative ScreenMetricLab QA profile; not measured on the named device in this review. |
| Device pixel ratio | 3 | Representative testing value; verify window.devicePixelRatio in the target browser and display mode. |
| Record year | 2023 | Model-generation context; verify the exact configuration. |
| Reference CSS area | 400,760 CSS px² | Calculated from the normalized width and height; not physical screen area. |
Manufacturer-verified layer
The sourced layer establishes the named model, display diagonal, native pixel grid and stated pixel density. Large mainstream iPhone viewport similar to Pro Max browser layout testing. These hardware facts do not establish the dimensions available to a webpage or prove how a specific browser will render at a particular moment.
Browser-dependent layer
The 430 × 932 CSS profile is useful for large-screen iPhone wrapping and reachability, but it is a testing scenario rather than a manufacturer specification. Capture innerWidth, innerHeight, visualViewport and devicePixelRatio on the target browser when a release decision depends on exact behavior.
At DPR 3, the mapping uses 3 in each direction and 9 raster pixel units of area (DPR²). Browser zoom, OS scaling, and device downsampling can change the observed result.
Responsive testing decisions
This record is most useful when the test has a clear layout question and the observed browser state is saved with the result.
Render real navigation, forms and cards at 430 CSS pixels, then check wrapping, truncation and stacking instead of treating the profile as a universal breakpoint.
On iPhone 15 Plus, repeat large-screen iPhone wrapping and reachability in portrait and landscape, with browser controls and the on-screen keyboard present where relevant. Record the visual viewport as well as the layout viewport.
For iPhone 15 Plus, inspect responsive images, icons, canvas output and screenshots at the representative DPR 3. Use the measured DPR for production calculations rather than inferring it from the native grid.
Use the iPhone 15 Plus profile with increased text size and long labels, then operate the interface by keyboard or touch. Confirm controls remain reachable and at least 44 by 44 CSS pixels.
Limits of a static record
A model name and portrait reference cannot reproduce every browser, accessibility, orientation, keyboard, or safe-area condition.
Evidence and provenance
Apple is cited for the 6.7-inch diagonal, 1290 × 2796 native grid and 460 PPI. The 430 × 932 CSS profile and DPR 3 are representative ScreenMetricLab testing values, not manufacturer claims or real-device measurements.
Review method: AI-assisted desk research checked the named model against the linked primary manufacturer specification. An editor reviewed the published facts, model scope and limitations. CSS viewport and DPR values remain explicitly unmeasured testing profiles.

Frequently asked questions
No. It is a representative QA profile. This review verified manufacturer hardware specifications but did not measure a live browser on the named device.
Window size, browser controls, zoom, display scaling, orientation, keyboard state, split view and accessibility settings can change the CSS space available to a page.
Usually not. Responsive CSS reacts to the live CSS viewport. Native physical pixels are useful for hardware and media context, not as an automatic layout breakpoint.
Use it as one documented scenario, test adjacent widths and difficult content, then confirm important behavior in the actual browsers and device states your audience uses.
