Buy 6.3-inch glass listed for the iPhone 17 Pro. Listings that name both the 17 Pro and 18 Pro are just as good, since the two share identical dimensions. Case-friendly glass with a tray suits most people.
17 Pro and 18 Pro: one protector
| iPhone 17 Pro | iPhone 18 Pro | |
|---|---|---|
| Display | 6.3-inch | 6.3-inch |
| Dimensions | 150.0 × 71.9 × 8.75 mm | 150.0 × 71.9 × 8.75 mm |
| Same protector? | Yes when listed for both | Yes when listed for both |
This matters mostly for stock. Once a model is replaced, retailers stop stocking its accessories. The 17 Pro won't have that problem for a while, because every 18 Pro protector that lists both models is also a 17 Pro protector. Don't be put off by a title that leads with "18 Pro"; check the model list in the description.
Glossy glass and Apple's anti-reflective coating
Apple's iPhone 17 generation added an anti-reflective coating to the Ceramic Shield 2 front glass. Standard glossy protectors sit on top of that coating, so the phone will reflect more light with the protector on than without it. Most people only notice outdoors. If you bought the phone partly for its outdoor visibility, go without, or try a matte protector knowing it softens the image. For everyone else, the scratch protection is still worth a little extra glare.
What to buy
When to replace a 17 Pro protector
- Cracked: replace it. It did its job, but cracks catch skin and let in grit. See cracked protector.
- Smears that won't wipe off: the oleophobic coating has worn out, usually after many months. Replace it if that bothers you.
- Lifting corners: usually your case pushing on the glass. See lifting at the edges.
Questions people ask
Do iPhone 18 Pro screen protectors fit the iPhone 17 Pro?
Yes, when listed for both. Apple's figures give the two phones identical outer dimensions, and brands including Spigen, Ailun and JETech sell one protector for both.
Does the iPhone 17 Pro need a screen protector with Ceramic Shield 2?
It's more scratch-resistant than older iPhone glass, but grit harder than glass still marks it. A protector is cheap and replaceable; going without is reasonable if you don't mind small marks.
