For the Google Pixel 9, when you ask about the smallest pixel in ''full dimensions'', not screen resolution, you’re talking about the camera image sensor’s pixel size, not the display pixels.

Here’s the actual camera pixel size for the Pixel 9:

📸 Main rear camera (wide):
* Sensor pixel size: ≈ 1.12 µm (micrometers) per pixel on the main sensor. PhoneArena<ref>{{cite web|title=PhoneArena|url=https://www.phonearena.com/phones/Google-Pixel-9_id12284|publisher=phonearena.com|access-date=2025-12-20}}</ref>

This is the smallest individual imaging pixel on the regular Pixel 9’s camera sensor (the main camera used for most photos).

For comparison:
* The ultrawide sensor has ≈ 0.70–0.80 µm pixels. hmc-tech.com<ref>{{cite web|title=hmc-tech.com|url=https://hmc-tech.com/mobile/pixel-9a-vs-pixel-9|publisher=hmc-tech.com|access-date=2025-12-20}}</ref> (so technically the absolute smallest physical pixel among the onboard cameras is on the ultrawide sensor)

If you also look at the Google Pixel 9a or other Pixel variants:
* The Pixel 9a’s main camera pixels are about 0.8 µm – smaller than Pixel 9’s main camera pixels.

So, in full physical dimensions (micrometers):
* 📏 Smallest camera pixel on Google Pixel 9 (main): ~1.12 µm
* 📏 Smallest overall camera pixel on the device (ultrawide): ~0.7–0.8 µm
* 📏 Smaller still on Pixel 9a main camera: ~0.8 µm

If you want, I can calculate the actual physical sensor size (mm) of the main Pixel 9 camera sensor too.
