CSS px are the units media queries see. Visible heights subtract the status bar and the Chrome on Android bars as set in our device profiles; real bar heights vary with settings and scrolling. The release year is that of the first model with each screen.

What this means for your layout

How the width difference affects your layout

The Pixel 9 Pro is 15 CSS px wider (427 vs 412, 4% more). One common breakpoint falls between them: (min-width: 414px) (a common large-phone test width) matches the Pixel 9 Pro but not the Pixel 9, so a rule written for that width applies on only one of the two.

In a 2-column card grid with 16 px page padding and 16 px gaps, each card is 189 px wide on the Pixel 9 Pro and 182 px on the Pixel 9. Check that buttons, prices and long words still fit in the narrower one.

Pixel density and image sizes

The Pixel 9 Pro has the denser screen: 3× against 2.625×. A full-width image (sizes="100vw") needs about 1281 px on the Pixel 9 Pro and 1082 px on the Pixel 9 to look sharp.

With a srcset such as 640w, 828w, 1080w, 1290w, 1440w, 1640w, 2048w, the browser would normally pick the 1290w file on the Pixel 9 and the same one on the Pixel 9 Pro.

The Pixel 9's ratio of 2.625 is fractional: one CSS pixel isn't a whole number of device pixels, so 1 px borders and hairlines can be rounded unevenly. Check thin lines on that screen rather than assuming they match.

How much fits above the fold

On first load about 856 px of the page is visible on the Pixel 9 Pro and 828 px on the Pixel 9: 28 px less (3%) on the Pixel 9, roughly 1 line of 16 px body text at a 1.5 line height.

If your main button sits just above the fold on the Pixel 9 Pro, it can end up below it on the Pixel 9. Keep the headline and the main action within the first 828 px, and size full-screen sections with 100svh rather than 100vh — see the 100vh problem on mobile.

In landscape

Turned sideways, the Pixel 9 is 924 px wide and the Pixel 9 Pro 952 px. The visible height drops to about 332 and 347 px, so a 64 px sticky header covers 19% and 18% of the screen — under the 25% at which MobileCheck flags fixed bars covering the page.

Same browser engine

Both run Android, so both render with Chromium, the engine behind Chrome. Engine quirks are the same; the differences above come from size and density alone. See how to test a website on Android.

Frequently asked questions

Is the Pixel 9 screen bigger than the Pixel 9 Pro?

In CSS pixels, which decide how much of a page fits, the Pixel 9 Pro is larger: 427 × 952 against 412 × 924. The Pixel 9 Pro has more physical pixels (1281 × 2856), which makes it sharper rather than roomier.

Do I need different CSS for the Pixel 9 and the Pixel 9 Pro?

Only if your breakpoints fall between 412 and 427 px: a min-width query at 414px applies to one and not the other. A fluid layout handles both without device-specific rules.

How much of a web page is visible on the Pixel 9 vs the Pixel 9 Pro?

About 412 × 828 CSS px on the Pixel 9 and 427 × 856 on the Pixel 9 Pro when a page first opens in portrait, after the status bar and Chrome on Android's bars. Bar heights are our device profiles' estimates.
