SAFE – Ample Clearance

Your webcam cover (1.0mm) is thinner than the lid gap (1.0mm). There is 0.0mm of clearance. Safe to use.

How to Measure Your Laptop's Lid Gap
📄 The Paper Test (Easy)

Standard printer paper is approximately 0.1mm thick. Close your laptop gently and try sliding sheets of paper into the gap near the webcam.

  • 5 sheets fit ≈ 0.5mm gap
  • 10 sheets fit ≈ 1.0mm gap
  • 15 sheets fit ≈ 1.5mm gap
  • 20 sheets fit ≈ 2.0mm gap
📐 Caliper Method (Precise)

Use a digital caliper to measure the distance between the screen bezel and the keyboard deck at the webcam location when the lid is gently closed.

Safety Tips
  • Always keep ≥0.3mm safety margin between cover thickness and lid gap.
  • Slide-type covers are generally thinner than magnetic ones.
  • MacBook models have very tight clearances (~0.5-0.7mm) – use ultra-thin covers only.
  • Never force your laptop closed if you feel resistance – the screen can crack.
  • Remove the cover if you notice imprints on the screen or keyboard marks.
  • Consider a physical shutter built into the laptop (some ThinkPads and HP EliteBooks have this).
Frequently Asked Questions
Yes, a webcam cover that is too thick can absolutely damage your laptop screen. When you close the lid, the cover creates a pressure point on the display panel. Over time, this can cause permanent pressure marks, delamination of screen layers, or even cracks. This is especially risky for modern ultrabooks and MacBooks, which have extremely tight tolerances — often less than 1mm of clearance between the screen and keyboard when closed.
The safe thickness depends entirely on your specific laptop model's lid gap. As a general rule, your webcam cover should be at least 0.3mm thinner than the measured gap. For MacBook users (gap ~0.5-0.7mm), only ultra-thin covers of 0.5mm or less are recommended. For ThinkPad or business laptops with larger gaps (~1.5-2mm), covers up to 1.2mm are typically safe. Use our tool above to check your specific combination.
Slide-type covers tend to be thinner (typically 0.5mm to 0.9mm) because they use a simple sliding mechanism with adhesive backing. Magnetic stick-on covers often range from 0.8mm to 1.5mm due to the magnet layer. For tight-clearance laptops, a slide-type cover is generally the safer choice. However, always check the manufacturer's specified thickness before purchasing.
MacBooks (especially MacBook Air and MacBook Pro models from 2016 onwards) have notoriously tight clearances — typically between 0.5mm and 0.7mm at the webcam area. Only the thinnest webcam covers (≤0.5mm) are safe to use. Apple has officially warned against using camera covers on MacBooks, as the tight tolerances can lead to display damage. Some users have reported cracked screens from covers as thin as 0.8mm on MacBook Pro models.
The easiest method is the paper test: standard printer paper is about 0.1mm thick. Gently close your laptop and count how many sheets you can slide into the gap near the webcam without resistance. Multiply by 0.1mm for your approximate gap. For precise measurement, use a digital caliper to measure the distance between the screen bezel and keyboard deck at the webcam position when the lid is gently closed. See our illustrated guide above.
Yes, but with extra caution. Touchscreen laptops often have slightly different bezel designs. The webcam cover should only be applied to the bezel area around the camera, never on the actual display area. Make sure the cover doesn't interfere with the touch functionality or the bezel's structural integrity. The same thickness guidelines apply — measure your lid gap and choose accordingly.
The thinnest webcam covers on the market are around 0.5mm thick. The SpiShutter Ultra Thin (0.5mm) and Jelly Comb Ultra Thin (0.6mm) are among the slimmest options available. These ultra-thin slide covers are specifically designed for MacBooks and other tight-clearance laptops. Always verify the manufacturer's thickness specification before buying, as many generic covers are 1.0mm or thicker.
External clip-on webcam covers that attach to the outside of the laptop lid are an alternative worth considering. They don't add any thickness between the screen and keyboard, so there's zero risk of screen damage. However, they can be bulkier when carrying the laptop and may not work well with all lid designs. A thin slide-type internal cover remains the most convenient option for most users — as long as the thickness is verified.
