Smaller accessory market than iPhone, but the right options exist. Verified compatible with Pixel's optical under-display fingerprint sensor.

The Pixel 9 Pro is 6.3"; the 9 Pro XL is 6.8". They take different protectors. Always verify the listing matches your specific model — Amazon listings often combine sizes in the title but ship one specific size.
Pixel uses an optical sensor — different to Samsung's ultrasonic. The optical sensor flashes the screen briefly and reads the fingerprint reflection through the glass. It's reasonably forgiving of protector thickness, but two things help: stick to brand-name protectors (Spigen, amFilm, ESR), and re-register your fingerprints after fitting.
Avoid privacy filters on Pixel — the angle filter blocks the reflection the optical sensor needs.
The Pixel 9 Pro Fold has two displays — outer cover screen takes flat glass; inner foldable screen needs flexible TPU film only. Pixel 9 Pro Fold protectors →
