A stiff neck at 4 p.m. or a sore lower back after a long workday usually isn’t bad luck. It’s often a sign that your desk is set up for the furniture, not for you. An ergonomic desk setup fits your workspace to your body, and most of it costs little or nothing.
This guide walks through the setup in the order that matters: chair first, then monitor, then keyboard and mouse. The recommendations follow widely used workplace ergonomics guidance, including the US Occupational Safety and Health Administration’s (OSHA) computer workstation advice. It’s part of our wider guide to digital wellness.
Start with the chair
Your chair sets the height for everything else, so adjust it before touching the desk or screen.
- Seat height: sit with your feet flat on the floor and your knees roughly level with or slightly below your hips. If your feet don’t reach the floor once your arms are at desk height, use a footrest or a sturdy box.
- Seat depth: leave a gap of about two to four fingers between the front edge of the seat and the back of your knees.
- Back support: sit all the way back so the chair supports the natural curve of your lower back. No lumbar support? A small cushion or rolled towel works.
- Armrests: set them low enough that your shoulders stay relaxed, not hunched. If they stop you getting close to the desk, lower or remove them.
Position your monitor
Poor monitor placement is the most common cause of neck pain at a desk. OSHA’s guidance boils down to three points:
- Directly in front of you: so your head, neck and body face forward. If you use two screens equally, center them as a pair; if one is your main screen, center that one.
- At least 50 cm (20 inches) away: with 50–100 cm (20–40 inches) a comfortable range for most people. A good test: you can read the text without leaning in.
- Top of the screen at or slightly below eye level: so you look slightly down toward the middle of the screen without tilting your head.
Tilt the screen back slightly so it faces your line of sight. If you wear bifocals or progressive lenses, lower the monitor a little more so you don’t tip your head back to read. Distance and height also affect your eyes; see our guide to screen distance for your eyes.
Keyboard and mouse
- Height: place the keyboard so your elbows bend at roughly 90 degrees or slightly more, with your upper arms hanging relaxed close to your sides.
- Wrists: keep them straight and in line with your forearms, not bent up, down or sideways. Fold the keyboard’s back legs away if they angle your wrists upward.
- Mouse: keep it right next to the keyboard at the same height, so you don’t reach out to the side.
- Rest, don’t anchor: wrist rests are for pauses between typing, not for pressing your wrists into while you type.
- Shortcuts: learning a few keyboard shortcuts cuts thousands of small mouse movements a day.
Working on a laptop
Laptops force a trade-off: when the keyboard is at the right height, the screen is too low, and you end up hunched over. That posture is behind a lot of “laptop neck” pain. The fix is to separate the two:
- At a regular desk: raise the laptop on a stand or a stack of books so the screen top is near eye level, and use a separate keyboard and mouse.
- On the move: keep sessions short, sit at a table rather than on a sofa or bed, and take more frequent breaks.
- Avoid working from bed: Propping a laptop on your knees bends your neck sharply for long stretches.
Lighting and glare
Place your screen at a right angle to windows so daylight doesn’t shine directly onto or behind it. Use soft, even room lighting, and add a desk lamp aimed at papers rather than at the screen. Glare makes you lean and squint, which brings back the neck strain you just fixed.
The best posture is your next posture
Even a perfect setup won’t protect you if you stay frozen in one position all day. Change position often, stand up at least once every 30–60 minutes, and walk during phone calls when you can. Our guide on how to move more during the day has simple ways to build that in.
15-minute desk setup checklist
- Feet flat on the floor or a footrest
- Knees about level with hips
- Lower back supported by the chair or a cushion
- Shoulders relaxed, elbows close to your sides at about 90 degrees
- Wrists straight while typing
- Mouse beside the keyboard at the same height
- Monitor directly in front of you, at least an arm’s length away
- Top of the screen at or slightly below eye level
- No glare from windows or lights on the screen
- Laptop raised, with a separate keyboard and mouse
When to see a professional
Setup changes often ease aches within a few weeks. See a doctor or physiotherapist if:
- Pain lasts more than a few weeks despite changes to your workspace
- You have numbness, tingling or weakness in your arms, hands or legs
- Pain spreads down an arm or leg, or wakes you at night
- Pain follows a fall or injury
Frequently asked questions
What is the correct monitor height?
The top of the screen should be at or slightly below eye level, so you look slightly down toward the center of the screen without tilting your head.
Is an expensive ergonomic chair necessary?
Not always. A chair with adjustable height and good lower-back support covers most needs. A cushion, a footrest and a monitor riser can make a basic chair work well.
Is it okay to cross your legs while sitting?
Occasionally, yes. Problems come from holding any position for hours. Keep changing position and get up regularly.
The bottom line
A good ergonomic desk setup takes about 15 minutes: adjust the chair, raise the screen, bring the keyboard and mouse close, and control glare. Then keep moving. Your neck, back and wrists will notice the difference within days.
