Why are laptops bad for your neck?

Because the screen and the keyboard are bolted together. Ergonomics asks for the screen near eye level and the keyboard near elbow level, roughly 30 to 40 cm apart vertically. A laptop cannot provide both: put the keyboard where your hands want it and the screen is far too low, and raise the screen and your wrists are in the air.1

There is no posture that solves this. The device geometry is the problem.

How bad is it in practice?

A laptop on a desk puts the screen roughly 25 to 30 cm below eye level for most adults, which means looking down at around 30 to 40 degrees. Sustained for a working day, that is the postural equivalent of reading a phone for eight hours.

A laptop actually on your lap is worse — closer to 60 degrees of neck flexion — and it is how a great many people work at home.

What is the fix?

Separate the screen from the keyboard. That is the whole answer, and it costs very little.

A stack of books under the laptop and a cheap external keyboard resolves the great majority of laptop-related neck strain. You do not need a designed product.

What height should the screen be?

The top of the screen at or slightly below eye level, roughly an arm's length away, tilted back very slightly.2 If you wear varifocals or progressive lenses, go lower — otherwise you will tip your head back to find the reading section of the lens, which produces a different neck problem.

What if I have to work on a bare laptop?

Sometimes you do — on a train, in a café, at someone else's desk. Limit the damage rather than pretending it is fine.

  1. Raise it on whatever is available. A bag, a book, a tray.
  2. Sit back with your back supported rather than hunching over the machine.
  3. Cap the session. Treat unsupported laptop work as something you do for 30 to 45 minutes, not four hours.
  4. Reset between sessions. Stand up, look up, move your neck through its range, roll your shoulders.
  5. Do the real setup for the long stretches. Save the deep work for a desk where the screen is at the right height.

Does a standing desk fix it?

Not on its own. Standing changes which muscles get tired; it does not change screen height. A laptop on a standing desk without a stand puts the screen even further below eye level, because your eye height went up and the screen did not.

The variable that matters is whether the screen is at eye level and whether you change position regularly — not whether you are sitting or standing.3

What else should change?

Screen height is the biggest single factor, but it is not the only one. Chair height determines where your elbows sit; whether your feet are supported determines whether you slide forward; and how often you move determines whether any of it matters. Fix the screen first, then look at the chair.
