Laptop stand height calculator
How to use a laptop ergonomically
A laptop’s screen and keyboard are joined, so one of them is always in the wrong place. For anything longer than a quick job, raise the laptop until the top of its screen is near eye level, and type on a separate keyboard and mouse at elbow height: that is what the UK HSE, OSHA and Cornell University all recommend. Measure how far your eyes are above the desk and how high the open screen reaches, and the calculator gives the stand height.
Raise it 36.5 cm
14.4 in to eye level
- Lift to eye level
- 36.5 cm · 14.4 in
- From the desk to the underside of the laptop, with the laptop sitting flat. The top of the picture then meets eye level (HSE, Cornell).
- OSHA’s range
- 24.1–29.8 cm
- 9.5–11.8 in. A lower stand that puts the screen centre 15–20° below eye level at 60 cm.
- Eyes above the desk
- 57.5 cm · 22.6 in
- Your measurement.
- Top of the screen now
- 21.0 cm · 8.3 in
- Your measurement. Picture height 18.8 cm · 7.4 in.
Only raise the laptop once you have a separate keyboard and mouse: typing on a raised laptop lifts your hands and shoulders.
Why laptops are awkward
Cornell University’s ergonomics guidance puts it plainly: the design of laptops breaks a basic ergonomic rule, because the keyboard and screen are joined. With the keys at a comfortable height, the screen is too low and you bend your neck; with the screen at eye level, the keys are too high for your hands. The HSE’s workstation checklist treats a keyboard separate from the screen as a requirement, unless the task makes it impracticable, such as when you need to use a portable.
So the advice is the same everywhere: for prolonged use, raise the screen and type on separate equipment. The HSE says to use a docking station or a firm surface with a full-size keyboard and mouse, and notes that raiser blocks are commonly used to lift the screen. OSHA’s checklist says a laptop used as your main computer should be set up like a desktop. Cornell suggests a separate keyboard and mouse for full-time use, with the laptop raised on a stable support.
How the stand height is worked out
The stand has to make up the gap between your eyes and the top of the screen: stand height = eyes above the desk − top of the screen above the desk. Both are easy to measure with the laptop open on the desk. In the example, your eyes are 57.5 cm above the desk and the top of the picture is 21 cm above it, so the stand needs to lift the laptop 36.5 cm (14.4 in) for the top to meet eye level, as the HSE and Cornell suggest.
OSHA allows the top of the screen slightly below eye level, with the centre of the screen 15 to 20 degrees below. For a 14-inch 16:10 laptop 60 cm away, that window is a stand of 24.1 to 29.8 cm (9.5 to 11.8 in), which the calculator also shows. Check a stand’s maximum height before you buy one; a sturdy box or a stack of books works too.
If you don’t want to measure, the calculator estimates. Your eyes above the desk are your seat height plus 0.459 of your height (the seated eye height ratio from the ANSUR II body-size survey) minus the desk height. The top of the screen is the base thickness plus the hinge-to-picture distance and the picture height, multiplied by the sine of the lid angle. A 14-inch 16:10 screen is 18.8 cm tall, so at 110° with a 1.6 cm base and 1.5 cm below the picture it reaches about 20.7 cm. Stands that tilt the laptop change this, so measure again with the laptop on the stand.
External keyboard and mouse
- Keyboard at elbow height, directly in front of you, wrists straight (OSHA). The HSE says just below elbow height. The desk height calculator gives the numbers for your chair and desk.
- Mouse beside the keyboard, at the same level and in line with your elbow, so you don’t reach (HSE, OSHA).
- Screen at about arm’s length once raised; the monitor distance calculator checks it.
A new keyboard can feel strange for a few days. Our sister site Quick Gesture has a typing speed test you can use to see when you’re back up to speed.
Working from the sofa or the kitchen table
Not every home has a desk. For short spells, Cornell suggests sitting back in a comfortable chair and finding the most neutral wrist position you can, even with the laptop on your lap. For longer work, go through this list and fix what you can.
| Problem | Fix |
|---|---|
| Looking down at the laptop for hours | Raise it on a stand, a box or books, and add a separate keyboard and mouse. |
| Kitchen chair too low for the table | Sit on a firm cushion to raise yourself, as the HSE suggests. |
| Feet dangling once you sit higher | Put a footrest, a box or a stack of books under them. |
| No support for your lower back | Put a cushion or rolled towel behind the small of your back. |
| Table edge digging into your wrists | Leave space in front of the keyboard to rest your hands (HSE), and pad or round off a sharp edge (OSHA). |
| Glare from a window on the screen | Turn so the window is to your side; OSHA suggests placing screens at right angles to windows. |
| Slumped on the sofa | Keep it short: OSHA’s checklist says to change posture regularly and keep usage time short when you work on a laptop away from your usual set-up. |
| Hours without moving | Take short, frequent breaks; the HSE’s example is 5 to 10 minutes every hour. |
On dark winter afternoons you will be working by lamplight more. The HSE suggests local lighting such as a desk lamp, placed so it doesn’t cause glare by reflecting off the screen, walls or other surfaces.
Common mistakes
- Raising the laptop and still typing on it. Your hands and shoulders go up with the keys. Only raise it once you have a separate keyboard.
- A stand that is too low to make a difference. Check the numbers above.
- Tilting the screen far back to see it from above, which catches ceiling lights.
- Carrying everything in one heavy shoulder bag. If the laptop and its accessories weigh 10 lb (4.5 kg) or more, Cornell suggests a bag you can pull along.
General information, not medical advice. See a GP, physiotherapist or occupational health service for pain, tingling or numbness that doesn’t settle. In the UK, if you work from home long-term or split your time between home and the office, your employer must assess your home workstation, and the HSE says workers can’t be charged for equipment the assessment shows they need. Our desk set-up checklist explains more.

Questions
How high should a laptop stand be?
High enough that the top of the screen reaches about eye level: your eye height above the desk minus the height of the screen’s top edge. That is often 30 cm or more, so check a stand’s maximum height before you buy.
Is it bad to use a laptop on your lap?
For a short spell it is fine; Cornell even suggests sitting back with the laptop on your lap for occasional use. For hours at a time, set it up on a table, raised, with a separate keyboard and mouse.
Do I need an external keyboard with a laptop stand?
Yes. Once the screen is at eye level, the laptop’s own keys are far too high to type on comfortably. The HSE, OSHA and Cornell all pair a raised screen with a separate keyboard and mouse.
Can I work at the kitchen table?
Yes, with a few fixes: a cushion to raise you to the table, something under your feet if they dangle, support for your lower back, the laptop raised and a separate keyboard and mouse. Take regular breaks.
What angle should a laptop screen be?
Once raised, about upright, tilted back a little so it faces your eyes; OSHA suggests a tilt of 10 to 20 degrees for monitors. Check that the tilt doesn’t pick up reflections from the ceiling lights.
