Targeting the Surface Pro 9 in CSS
Device-specific media queries are brittle — a new model with the same width will not match. Use them for genuine per-device fixes only, and prefer width buckets for layout.
/* Target Surface Pro 9 specifically */
@media only screen
and (device-width: 1440px)
and (device-height: 960px)
and (-webkit-device-pixel-ratio: 2) {

}
/* More useful in practice — the width bucket it falls into */

Questions about the Surface Pro 9 screen
What is the screen size of the Surface Pro 9?
The Surface Pro 9 has a 13-inch display. In CSS the viewport measures 1440 × 960 px in portrait, and the panel itself has 2880 × 1920 physical pixels at 267 PPI.
What resolution should I design for on the Surface Pro 9?
Design at 1440 × 960 and export assets at 2×. That gives you 2880 × 1920 px images, which is exactly what the panel renders. Designing directly at 2880 × 1920 means every measurement is 2 times larger than the CSS values you will write.
What is the device pixel ratio of the Surface Pro 9?
The Surface Pro 9 reports a device pixel ratio of 2. One CSS pixel therefore covers 4 device pixels. You can read it in JavaScript with window.devicePixelRatio.
Does the Surface Pro 9 always report 1440 px?
No — on Windows the CSS viewport is the panel divided by the display scale, and that is a user setting. 1440 × 960 is what you get at the 200 % scale Windows recommends for this panel, which is what most units ship with. Change it in Settings → System → Display and every CSS pixel measurement changes with it. The table above lists the viewport at each scale step.
Which other devices have the same viewport as the Surface Pro 9?
2 other devices share the 1440 × 960 CSS viewport: Surface Pro 11, Surface Laptop 7 15″. A layout that works on one works on all of them.
