For almost every iPhone, the best buy is model-specific tempered glass with an alignment tray, such as Spigen's EZ Fit, or a budget three-pack from Ailun or JETech. What matters is matching the exact model, and 2026 made that easier in two places: 18 Pro glass fits the 17 Pro, and 18 Pro Max glass fits the 17 Pro Max.

How to choose, in order
- Match the exact model. Screen diagonals repeat across the range (the 18 Pro, 17 Pro, 17 and 16 Pro are all 6.3-inch), so a matching size doesn't mean a matching protector.
- Decide case-friendly or edge-to-edge. If you use a case, choose case-friendly. See the difference.
- Get a tray if you've never fitted glass. It fixes the only step that's genuinely hard. See alignment frames.
- Pick a finish. Clear for most people; privacy for public transport; matte if glare really bothers you.

Which iPhones share screen protectors?
In the current range: the iPhone 18 Pro and 17 Pro; the 18 Pro Max and 17 Pro Max; the 17e and 16e. Always choose a product whose maker lists both models.
Do I need a screen protector on an iPhone with Ceramic Shield 2?
It resists everyday scratches better than older iPhones, but grit and sand can still mark it, and a replacement display costs far more than a protector. It's optional if you use a lipped case and don't mind small marks.
