What this viewport size means
430 × 932 represents the preset browser viewport in CSS pixels, not necessarily the physical display resolution. DPR 3 is reference metadata: the tester does not change pixel density or emulate the device OS or browser engine.
Portrait and landscape
The rotated width may activate rules intended for roomier layouts. Check two-column forms and side panels under the reduced height constraint.
What to check
Look for fields and images that stretch without a useful limit. Compare spacing and line length with iPhone 15 Pro. A second column is only useful if its content remains comfortable to read.
How to test this size
Open the tester, enter a URL and select “Test website”. In the workspace, choose “Add device” and select iPhone 15 Pro Max if it is not already active. Its default size is 430 × 932 CSS px. Rotate swaps the dimensions. The link below opens the tester without automatically selecting a preset.
