01How to choose a screen protector: the five calls
To choose a screen protector, decide on material first, then how much of the screen it covers, then the finish, then whether it works with your case, and last how you'll install it. Make the calls in that order and you'll rule out most of the shelf in under a minute.
-
Material: glass or film
Tempered glass spreads the force of a drop and feels like the bare screen. Film (TPU or PET) is thinner and won't crack, but it scratches more easily and feels softer under your finger. Glass is the default; film makes sense for curved or foldable screens. Details in tempered glass vs plastic.
-
Coverage: edge to edge, or just inside
Full-cover glass reaches the black border for a cleaner look. Case-friendly glass stops a millimeter or so short so your case's lip doesn't push the edges up. If you always use a case, case-friendly is the safer bet.
-
Finish: clear, privacy, matte or blue light
Clear keeps the screen as sharp and bright as it was. Privacy darkens the view from the side. Matte cuts glare and fingerprints but softens text slightly. Blue light filters add a faint tint that some people notice on whites.
-
Case fit
Check the listing says case-friendly or names cases it works with. A thick rugged case with a tall front lip needs a protector with a smaller footprint.
-
Install method
A frame or install box that clips onto the phone takes the guesswork out of alignment. Packs with two or three protectors give you a second try if dust gets under the first.
You don't need to spend much. A protector's job is to break instead of your screen, so a two- or three-pack of decent tempered glass beats a single pricey one: you get a spare for the inevitable crack or a botched install. Spend the extra on an install kit before you spend it on fancier glass.
02Every type, compared
| Type | Feels like | Good at | Trade-off |
|---|---|---|---|
| HD clear glass | The bare screen | Clarity, drop protection | Shows fingerprints like the original |
| Privacy glass | Slightly darker screen | Hiding the screen from the side | Dimmer, harder to share |
| Matte glass | Smooth, slightly textured | Glare, fingerprints, gaming swipes | Faint grain over text |
| Blue light glass | Bare screen, warmer whites | A warmer look all day | Night Shift or Eye Comfort does similar for free |
| TPU or hydrogel film | Soft, a little rubbery | Curved and foldable screens, self-healing light scuffs | Little drop protection |
| PET film | Thin plastic | Cheap scratch cover | Scratches easily, no drop protection |

03Phones with anti-reflective screens
Some recent phones ship with an anti-reflective coating on the front glass. Apple's Ceramic Shield 2 on the iPhone 17, iPhone Air and iPhone 17 Pro models has one, and Samsung uses anti-reflective Corning Gorilla Armor glass on the Galaxy S24 Ultra and S25 Ultra. A standard glass protector sits on top of that coating, so you get the protector's reflections instead of the phone's low-glare surface.
That doesn't mean skip protection. It means choose deliberately:
- Want the glare reduction back? A matte protector is the closest match, at the cost of a little sharpness.
- Want maximum clarity? HD clear glass protects the screen; accept a bit more reflection outdoors.
- Rarely drop the phone and use a case with a raised lip? Running bare is a reasonable choice on these models.
Ceramic Shield 2 is also rated by Apple for better scratch resistance than earlier iPhone glass, which makes the case for running bare a little stronger on those models. Scratches aren't the only risk, though. A drop onto a hard edge can still crack the screen, and replacing a protector costs far less than a display repair. See our screen protection for options cut for each model.
04Labels you can ignore
Protector packaging is full of numbers that sound technical and tell you very little.
- 9H. This is a pencil hardness rating: the glass resists a 9H graphite pencil. Almost every tempered glass protector claims it, so it doesn't separate good from bad. More in what 9H hardness means.
- 2.5D, 3D, 10D, 21D. 2.5D describes rounded edges. Beyond that, the numbers are marketing with no shared standard.
- "Military grade." There's no military standard for screen protectors.
- Oleophobic coating. This one matters. It's what makes fingerprints wipe off easily, and it wears down over time. See what an oleophobic coating does.
An iPhone 17 Pro and 17 Pro Max protector aren't interchangeable, and neither is a Galaxy S25 and S25+. Check Settings > General > About on iPhone, or use Find My Phone, before ordering.

Questions people ask
What is the best type of screen protector?
For most flat-screen phones, tempered glass. It feels like the original screen, spreads the force of a drop and resists scratches well. Film only makes more sense on curved or foldable screens where rigid glass can't follow the shape.
Is full cover or case-friendly better?
If you use a case, case-friendly. It stops just short of the edges so the case lip can't lift it. Full cover looks cleaner on a bare phone or a case with a very low front lip.
Should I put a screen protector on an iPhone 17?
It's a personal call. Ceramic Shield 2 is tough and has an anti-reflective coating that a glass protector covers up. If you drop your phone often or want a cheap replaceable layer, use one. If you're careful, going bare is reasonable.
Does 9H mean the screen protector is unbreakable?
No. 9H is a pencil hardness test for scratch resistance, and nearly every glass protector claims it. It says nothing about drop resistance, and tempered glass protectors are designed to crack before your screen does.
Are matte screen protectors good for gaming?
Many players like them because fingers glide easily and sweat smudges less. The slight texture softens fine text and makes the image a little less crisp, which is the trade for less glare.
