For privacy, use a removable magnetic privacy filter sized for your laptop, and take it off before closing the lid. For glare, a thin anti-glare film. Avoid thick glass or anything over the camera on thin laptops like MacBooks, which have very little clearance when closed.
What people actually use
| Type | For | Notes |
|---|---|---|
| Magnetic privacy filter | Privacy on trains and in offices | Easy on and off; must be removed before closing on most laptops |
| Adhesive-tab privacy filter | Privacy on older laptops | Tabs stick to the bezel; can leave residue |
| Anti-glare film | Bright offices, windows | Softens the image slightly |
| Tempered glass | Rarely needed | Adds thickness; risky on thin laptops |
MacBooks: mind the gap
MacBook lids close with very little space between screen and keyboard. Apple warns that leaving a camera cover on can damage the display when the lid closes. The same logic applies to thick filters and protectors. Magnetic privacy filters made for MacBooks are designed to be removed before closing; get into the habit.
Sizing
Laptop filters are sold by diagonal and aspect ratio (16:9, 16:10 or 3:2), and by exact model for MacBooks. Measure the visible screen, not the lid, and check the aspect ratio in your laptop's specs.
Privacy trade-offs
Laptop privacy filters dim the screen and narrow viewing angles like phone privacy glass. See privacy protectors explained.
Questions people ask
Can I close my MacBook with a privacy filter on?
Generally no. Thin laptops have little clearance, and Apple warns that covers can damage the display when closing. Remove the filter first.
Do laptop screens need a screen protector?
Rarely for scratches. Most people buy one for privacy or glare.
