Check which Deck you have: the OLED is 7.4-inch, the older LCD models are 7-inch, and their protectors don't interchange. If yours has the etched anti-glare screen, fit a matte protector or none at all, because glossy glass puts the reflections back.
Which Deck do you have?
| Model | Screen | Protector note |
|---|---|---|
| Steam Deck OLED | 7.4-inch OLED | Larger screen in the same body |
| Steam Deck LCD (original) | 7-inch LCD | Earlier model; smaller screen |
| Anti-glare editions | Etched glass | Matte already; don't cover with glossy glass |
The OLED model kept the same outer size while growing the screen, so protectors cut for the original Deck leave a visible border and can sit over the bezel. Listings usually say "OLED" or "LCD" explicitly; if one doesn't, skip it.
The anti-glare question
Valve sold Deck versions with etched anti-glare glass, which scatters reflections at the surface. Putting ordinary glossy glass over that surface hides the benefit you paid for. Your options are the same as on an anti-reflective phone: accept the extra glare, buy a matte protector, or go without and use a case.
What else to know
- Thumb wear: coatings go first where your thumbs rest, so treat protectors as consumable.
- Carry case pressure: the official case presses the controls towards the screen; avoid very thick glass with raised edges.
- Fan intake dust: clean the bezel before fitting, because dust collects along the top vent and gets dragged under the adhesive.
Questions people ask
Do Steam Deck LCD protectors fit the OLED?
No. The OLED screen is 7.4-inch against the LCD's 7-inch, so older protectors leave a border and can overlap the bezel.
Should I put glass on an anti-glare Steam Deck?
Only a matte protector. Glossy glass covers the etched anti-glare surface and reflections come back.
