A webcam cover only works if it fits. If it is too small, part of the lens stays open. If it is too big, it can block the sensors next to the camera. This guide shows how to choose the right size for a MacBook Air, MacBook Pro or MacBook Neo, and for any other laptop, phone, tablet or monitor.
What to look for in a webcam cover
- It covers the whole lens. Even a small gap lets the camera see.
- It is not bigger than needed. On a MacBook, Apple's support page says a cover can interfere with the ambient light sensor next to the camera.
- It is thin. Apple advises against covers thicker than 0.1 mm when you close the lid. Read more in our guide: Is a webcam cover safe for a MacBook?
- It leaves no residue. Adhesive-free film can be removed again without leaving marks.
How to choose the right size in three steps
- Look at the camera lens, the small dark circle at the top of the screen frame or display.
- Hold the available sizes next to the lens, one after the other.
- Pick the smallest size that fully covers the lens, so the sensors beside it stay free.
Because lenses differ from device to device, a set with several sizes is the easiest way to get a good fit.
What about the MacBook Neo?
Apple launched the 13-inch MacBook Neo in March 2026. It has a 1080p front camera, and Apple's Platform Security Guide describes an on-screen indicator that shows when the camera is active. A software indicator tells you what the system is doing, while a physical cover guarantees that the camera cannot see anything. The steps above apply to the MacBook Neo in the same way: hold the sizes next to the lens and choose the smallest one that covers it.
Sizes and sets from CamTag
Each CamTag set contains 25 reusable webcam stickers in 5 sizes, from 3.5 to 11 mm. They are only 0.1 mm thin and made of adhesive-free film, so they can be removed and reused without residue. One set covers the cameras of your laptop, phone, tablet and monitor.
Frequently asked questions

Can I use the same cover on my phone, tablet and monitor?
Yes. CamTag works on laptops, phones, tablets and desktop monitors. Choose the matching size for each device from the set.
Can I reuse a webcam cover on another device?
Yes. CamTag stickers can be removed and reapplied several times without losing effectiveness.
Will it leave residue?
No. CamTag uses adhesive-free film, so it leaves no residue on your device.
