Pixel 9 Pro XL screen protectors: its own size, and the fussier sensor

The Pixel 9 Pro XL is 162.8 × 76.6 × 8.5 mm with a 6.8-inch screen. The Pixel 9 Pro is a 6.3-inch phone in a much smaller body, and none of the listings we checked claims to fit both. Buy the one that names the XL.

An ultrasonic reader sends sound through whatever covers it, so the rules are the opposite of the optical sensors in Google's a-series:

• Thinner glass reads better. A thick "9H" slab is working against you here.
• Adhesive across the whole face. Edge-only adhesive leaves an air gap over the sensor, the most common failure of all.
• Skip privacy film. The louvre layer sits directly over the sensor area.

Re-enrol your fingerprints once the glass is on. Our fingerprint sensor guide covers both sensor types.

The Pixel hub lists every current model. For the optical-sensor models, see Pixel 9a and Pixel 8, 8 Pro and 8a, or our sensor-by-model guide.
