Here are the three main Pixel 9 lineup phones you’re asking about:

📱 Phones in the Pixel 9 series
* Google Pixel 9 – Standard model
* Google Pixel 9 Pro – Pro flagship with telephoto
* Google Pixel 9 Pro XL – Larger Pro variant with similar cameras business-standard.com<ref>{{cite web|title=business-standard.com|url=https://www.business-standard.com/technology/gadgets/pixel-9-series-all-you-need-to-know-about-the-made-by-google-smartphones-124081301923_1.html|publisher=business-standard.com|access-date=2025-12-20}}</ref>

===== 📸 Smallest camera pixel among them =====

When talking about the smallest ''actual physical'' pixel element on the imaging sensors (not display pixels):

1) Pixel 9 (standard)
* Main camera: 50 MP on a 1/1.31″ sensor — approx 1.2 µm pixel size
* Ultrawide: 48 MP on 1/2.55″ — approx ~0.7 µm pixel size PhoneArena<ref>{{cite web|title=PhoneArena|url=https://www.phonearena.com/phones/compare/Google-Pixel-9-Pro%2CGoogle-Pixel-9a/phones/12285%2C12443|publisher=phonearena.com|access-date=2025-12-20}}</ref>

2) Pixel 9 Pro / Pixel 9 Pro XL
* Main camera: 50 MP on 1/1.31″ — approx 1.2 µm pixel size
* Ultrawide: 48 MP on 1/2.55″ — approx ~0.7 µm pixel size
* Telephoto: 48 MP on 1/2.55″ — approx ~0.7 µm pixel size (All Pro models share the same camera sensor sizes except the XL being physically larger overall.)

📌 Smallest literal camera pixel:
👉 Across the Pixel 9, Pixel 9 Pro, and Pixel 9 Pro XL, the ultrawide and telephoto sensors’ individual pixel size (~0.7 µm) are the smallest physical pixels in the lineup — smaller than the main 50 MP pixels (~1.2 µm).

===== 📊 Summary =====

| Model          | Smallest Pixel Size (imaging)   |
| -------------- | ------------------------------- |
| Pixel 9        | ~0.7 µm (ultrawide)             |
| Pixel 9 Pro    | ~0.7 µm (ultrawide & telephoto) |
| Pixel 9 Pro XL | ~0.7 µm (ultrawide & telephoto) |

✔ So the smallest actual pixel in all three phones is roughly ~0.7 µm on the secondary sensors — and that’s the same whether you choose the Pixel 9, Pixel 9 Pro, or Pixel 9 Pro XL.

If you want, I can tell you which of these phones has the physically largest camera sensor overall, which usually means better photos in low light.
