iPhone 15 Pro viewport — 393 × 852 CSS px
This preset is part of the initial workspace. It is a starting point for a mobile page review, but nearby and intermediate widths still need testing.

What this viewport size means
393 × 852 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
Rotation produces a wide but shallow area. Inspect sticky headers and expanded panels so they do not leave too little room for the main content.
What to check
Compare it with iPhone 14: a small width change can move the last word of a heading or wrap an action button. Inspect long form labels and icon-and-text combinations; do not tie a breakpoint to a single phone name.
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 if it is not already active. Its default size is 393 × 852 CSS px. Rotate swaps the dimensions. The link below opens the tester without automatically selecting a preset.
