Build a Basic Webcam Cover from Tape and Cardboard

The fastest webcam cover is a small rectangle of cardboard or thick paper taped over your camera lens. Cut a piece roughly the size of your webcam's lens opening—usually between half an inch and one inch across—from a cereal box, index card, or old greeting card. Tape it in place with painter's tape or masking tape, which won't leave residue when you remove it. This cover slides on and off in seconds and costs nothing if you have tape at home.

The main limitation is that tape can leave marks on your laptop or monitor bezel over time, especially in warm rooms where adhesive softens. If you plan to use the cover daily, move on to one of the sliding designs below. For occasional use—say, during video calls you want to control—the tape method works fine.

Key Takeaways

  • A taped cardboard rectangle is the quickest cover and takes five minutes to make with materials you likely have at home.
  • A sliding cover made from a plastic card or thin wood slides smoothly and won't damage your screen or laptop frame.
  • A hinged cover using a small piece of duct tape as the hinge lets you flip the cover up and down without removing it.
  • Measure your lens opening before you cut so the cover sits flush and doesn't block the microphone or sensors nearby.
  • Test the cover's weight and balance before finalizing it—a cover that's too heavy will sag or fall off.

Measure Your Webcam Lens Before You Start

Open your camera app or video call software and look at the live feed to see exactly where your lens is. On a laptop, the camera is usually centered above the screen. On a monitor, it's typically in the bezel at the top center. Use a ruler to measure the lens opening itself—not the entire camera module, just the circular or oval glass part you can see.

Write down the width and height. Most built-in laptop cameras are between 0.5 and 0.75 inches across; external USB cameras vary more widely. Measure the distance from the lens to the nearest microphone hole or sensor, because your cover should not block those. If your camera has a privacy light (a small LED), make sure your cover won't cover that either—you want the light visible so you know when the camera is active.

Make a Sliding Cover from a Plastic Card

A sliding cover is more durable than tape and looks cleaner. Cut a rectangle from a plastic gift card, old credit card, or a piece of thin plastic (like a yogurt container lid) that is slightly wider and taller than your lens—about one inch by one and a quarter inches for a typical laptop camera. Round the corners with scissors so they don't catch on your screen or frame.

Tape a thin strip of plastic or cardboard to the top or side of your cover to act as a handle or slider. This strip should be about two inches long and stick out perpendicular to the cover so your finger has something to grip. Attach the handle with strong tape—duct tape or gaffer tape works better than masking tape for this. Position the cover so it slides smoothly in front of the lens without binding. Test it five times to make sure it moves freely before you call it done.

If your camera is on a laptop screen, you can tape the slider handle to the top bezel so the cover hangs down in front of the lens and slides up to uncover it. If your camera is on a monitor, tape the handle to the side so the cover slides left or right. The key is that gravity and friction should not fight you—the cover should move with light pressure.

Build a Hinged Cover with Duct Tape

A hinged cover flips up and down like a tiny door, so you never have to remove it. Cut a rectangle of cardboard or thin plastic slightly larger than your lens opening. Cut a second, smaller rectangle—about one inch by half an inch—from duct tape or gaffer tape. This tape rectangle will be your hinge.

Position the tape hinge along the top edge of your cover, with half of the tape stuck to the cover and half stuck to your laptop screen or monitor bezel, directly above the lens. Press firmly so the tape adheres well. Test the hinge by flipping the cover up and down ten times. If it feels loose or the tape is peeling, add a second strip of tape alongside the first one.

The advantage of a hinged cover is that you can flip it up during a call and flip it down when you're done, without ever setting it down or losing it. The disadvantage is that duct tape can leave a faint mark on your screen or bezel, especially if you leave it in place for months. If you're concerned about marks, use painter's tape or removable fabric tape instead—it holds less securely but won't damage the surface.

Reinforce Your Cover So It Doesn't Fall Off

A cover that's too light will blow away if you move your laptop or turn on a fan. A cover that's too heavy will sag or fall off from its own weight. Test your finished cover by gently tapping your laptop or monitor from the side. The cover should stay in place. If it shifts, add a small piece of tape to the bottom edge to hold it steady, or reinforce the attachment point at the top.

If you used a sliding cover, make sure the slider handle doesn't catch on anything when you move your laptop. If you used a hinged cover, make sure the hinge tape is pressed down firmly and doesn't peel at the corners. Check your cover once a week if you use it daily—tape adhesive weakens over time, especially in warm or humid rooms.

Alternatives to Homemade Covers

If you don't want to build a cover, commercial webcam covers cost between two and ten dollars and come pre-made in various styles. Some are thin plastic sliders, others are adhesive stickers, and some are small metal shutters. The advantage is that they're designed to fit standard camera sizes and won't damage your screen. The disadvantage is that you have to buy them and wait for delivery.

Some people use a small piece of electrical tape or a sticky note instead of building anything. These work in a pinch but are harder to remove cleanly and can leave residue. If you're in a hurry and don't have cardboard or plastic on hand, a sticky note is better than nothing—just don't leave it on for more than a few days.

Frequently Asked Questions

Will a webcam cover damage my camera or screen?

A well-made cover won't damage anything if you use the right tape. Painter's tape and masking tape are safe for screens and laptop frames. Duct tape can leave a faint mark if left in place for months, but it washes off. Avoid super-glue or permanent adhesive—use only removable tape.

Can I use a cover if my camera has a privacy light?

Yes, but make sure your cover doesn't block the light. The privacy light is usually a small LED next to or below the lens. Measure its position before you cut your cover, and leave a small gap so the light is visible. If the light is blocked, you won't know when the camera is active.

What if my webcam is on the side of my monitor instead of the top?

A sliding cover works best for side-mounted cameras because it slides horizontally. A hinged cover can work too, but the hinge tape needs to be positioned so the cover swings out to the side rather than up and down. Measure carefully so the cover doesn't hit the monitor frame when it opens.

How do I remove a cover without leaving tape residue?

Peel slowly and at a low angle—don't pull straight up. If tape residue remains, rub it gently with your thumb or a soft cloth. For stubborn residue, use a small amount of rubbing alcohol on a cloth, but don't pour liquid directly on your screen. Let the alcohol dry completely before using your camera.

Can I make a cover that works on an external USB camera?

Yes, but external cameras vary in size and shape. Measure your specific camera's lens opening and build a cover to fit. A sliding cover usually works best because you can adjust the slider handle to fit your camera's shape. Test it on your camera before you finalize the tape so you don't have to redo it.
