The Monitor Eye-Level Rule, Simply Explained
The eye-level rule is the simplest ergonomic idea in computing: the top of your screen should sit at or just below eye level. Get that one detail right and your neck stays neutral all day; get it wrong and you will crane or hunch for hours without noticing.
TL;DR / Quick Fix
Quick fix: sit upright, close your eyes, then open them and look straight ahead — the top of the screen should be at or just below that line. Raise or lower the monitor to match, sit an arm's length away, and fine-tune after a full workday.
Follow these steps
- Sit the way you actually sit. Sit in your normal chair, in your normal posture, feet flat. Adjusting the monitor for a posture you never use will leave it wrong for the posture you do use.
- Find your straight-ahead line. Close your eyes for a few seconds, then open them and look straight ahead. That line is your reference, and the top of the screen should sit at or just below it — the same target used in a proper arm setup.
- Raise or lower the monitor to match. Use the stand, arm, or a sturdy riser to move the screen until its top edge meets your line. Books under the base work as a temporary test before you buy anything.
- Set the distance to an arm's length. Hold your arm out toward the screen; your fingertips should nearly touch it. That distance keeps text readable without pulling your neck forward.
- Tilt the screen back slightly. Angle the top of the screen a little away from you. A slight tilt keeps the whole screen visible without moving your head as your eyes travel down.
- Live with it for a day, then adjust. Work a full day and notice where you feel strain. Raise it a touch if your neck bends down, or lower it if you catch yourself looking up.
What NOT to do
- Do not aim the center of the screen at eye level. The rule uses the top edge, because your eyes naturally rest a little below straight ahead.
- Do not measure eye level while standing. Your seated eye line is lower, and a monitor set for standing height will tower over you at the desk.
- Do not fix the height and ignore the distance. A screen at the right height but too far away still drags your neck forward.
- Do not stack the monitor on wobbly boxes. An unstable stack can topple, so use a proper stand or a stable riser for a permanent setup.
Frequently asked questions
What is the monitor eye-level rule?
Keep the top of the screen at or just below eye level when seated, so your gaze rests slightly downward across the screen.
Does the rule apply to laptops?
Only with a stand or dock. A laptop on a desk sits far too low, which is why a separate keyboard and a riser matter.
What if I wear bifocals?
You may need the screen a bit lower than the standard rule, since bifocal wearers tilt their heads to use the lower lens.
