Free webcam posture check

See how far your head and shoulders drift toward your screen once you start working. Your webcam compares you sitting tall with you typing or reading, and the whole thing runs in this browser tab.

Run the check

Sit tall for 5 seconds, then work as you normally do for 20. The check compares the two and tells you how far your head and shoulders moved. With setup it takes about a minute.

Before you press start

Your browser will ask to use your camera. The video is read by a pose model running in this tab. It is not uploaded and not recorded, and the camera turns off when the check ends or you leave the page. We never ask for your microphone.

How the check works

A laptop camera looks at you from the front, so it cannot read the angle of your neck the way a side photo can. What it can do is compare you with yourself. For the first 5 seconds it records where your ears, nose and shoulders sit while you hold your best upright posture. For the next 20 seconds it records the same points while you type or read. The result is how far your head moved forward and how much your shoulders rounded, measured against your own tall position.

The tracking is done by a pose model that runs as WebAssembly inside this page. Your video frames are not uploaded, and the only thing kept is your last result, in this browser, if you allow the page to store it. You can watch for uploads yourself on the proof page.

What your result means

Head drift and shoulder rounding are each scored from 0 to 100. Zero means you are where you were when you sat tall. Your band comes from whichever score is higher.

Stacked, under 34%
Your head and shoulders stayed close to where they were when you sat tall.
Drifting, 34% to 54%
Your head or shoulders moved away from your tall position. A screen that sits low or far away is worth checking at this level.
Laptop neck, 55% and up
Your head slid well forward of your shoulders, or your shoulders rounded toward the screen. 55% is the same line the LaptopNeck monitor uses when it raises an alert.

What this check does not tell you

This is a posture habit check, not a medical assessment. It does not diagnose anything, and a result in any band says nothing about whether you have or will have neck pain. Lighting, camera height and how you sat during the first five seconds all change the numbers, so compare results from the same desk and run it again on another day.

See a clinician if you have neck pain that spreads down your arm, numbness or weakness in your hands, pain after an injury, or headaches that are new or severe.

Questions about the posture check

Does my video leave my computer?

No. The camera feed is read by a pose model that runs inside this page, and the page sends no frames or landmarks anywhere. The camera turns off when the check ends or when you leave the page. The proof page shows a live upload meter and the steps to verify this yourself. See the proof page.

Why does the check compare me with myself?

A webcam looks at you from the front. A side photo is what you need to read the angle of your neck, and a front view cannot give you that. What a front view can see is how your ears, nose and shoulders move between two moments, so the check records you sitting tall, records you working, and reports the difference.

Do I need an account or an app?

No. There is no sign-up and nothing to install. It works in current versions of Chrome, Edge, Safari and Firefox on a computer with a webcam. The only thing saved is your last result, in this browser, and only so the page can show it to you next time.

How accurate is it?

It tracks a handful of body points as your camera sees them, so the numbers shift with lighting, how high the camera sits, and whether hair or a headset covers your ears. Treat a result as a comparison with your own tall posture on that day, and run it again on another day before reading much into it.

What should I do after a Laptop neck result?

Start with the setup. A screen that sits low or far away is one common reason a head drifts forward, and the monitor height calculator gives you a number to aim for. The forward head posture guide lists what studies have found, with sources, and the chin tuck page shows a short movement you can try at your desk.
