Distinct CSS widths in this range
These are the only viewport widths your CSS actually sees across all 15 models. Everything else is a difference in physical pixels, not in layout space.
Questions
What is the most common Windows Devices screen size?
Across the 15 Windows Devices models listed here, 1280 × 800 px is the most frequently repeated CSS viewport — 4 models share it. Building for that width covers the largest slice of the range.
Which Windows Devices has the largest screen?
The Surface Studio 2, with a 2250 × 1500 px CSS viewport and a 28-inch panel at 4500 × 3000.
Do I need a separate breakpoint for every Windows Devices?
No. These 15 models resolve to only 7 distinct CSS widths (1280, 1440, 1504, 1600, 1707, 1728, 2250 px). Layout should respond to those buckets, not to model names — and in practice a handful of well-chosen breakpoints covers all of them.
