Correct Desk and Chair Height: A Setup Guide

If you finish the working day with a stiff neck, an aching lower back or tingling wrists, your setup is almost certainly the culprit rather than your posture willpower. This guide gives you clear, measurable height rules for your desk, chair, monitor and keyboard, so you can build a workstation that keeps your body neutral all day. By the end you will know the exact target heights for your own height, and the cheap fixes that close any gaps.

1. Why height is the whole game

Ergonomics sounds complicated, but almost every desk-related ache traces back to a single idea: your body should sit in a neutral posture, where joints are neither stretched nor scrunched. When a surface is too high, your shoulders creep up towards your ears and your wrists bend back. When it is too low, you round your spine and crane your neck forward. Hold either position for eight hours and the strain compounds.

The order you adjust things matters. Always set the chair to fit your body first, then bring the desk to the chair, then the monitor and input devices to you. Working the other way round, fitting yourself to whatever the furniture happens to be, is how bad habits set in. Before you buy anything, it is worth reading our companion guide to choosing a desk so the surface you start with is the right depth and size for your room.

2. Setting your chair first

Your chair is the foundation, so dial it in before you touch the desk. Sit right back so your lower spine is supported, then adjust the seat height until three things are true at once:

• Your feet rest flat on the floor, with your thighs roughly parallel to the ground.
• Your knees sit at about a 90 to 100 degree angle, level with or very slightly below your hips.
• There is a two to three finger gap between the back of your knees and the front edge of the seat.

As a rough starting point, seat height usually lands between 40cm and 52cm from the floor for most adults. If your feet dangle, the chair is too high; if your knees rise above your hips, it is too low. The backrest should support the natural inward curve of your lower back, and armrests, if fitted, should let your shoulders relax with your elbows resting lightly at around 90 degrees. Browse our seating range for adjustable options that make these tweaks easy.

3. Getting the desk right

With the chair set, bring the desk to you. The target is simple: when your upper arms hang relaxed by your sides and your forearms rest on the desk, your elbows should form roughly a 90 degree angle and your forearms should be level with, or gently sloping down from, the desktop. For a large share of adults this puts the ideal desk height somewhere between 68cm and 76cm, with around 72cm to 74cm being the most common sweet spot for seated work.

Most fixed desks are built at about 73cm to 75cm, which suits people of average height but leaves taller and shorter users compromising. If your desk is too tall and cannot be lowered, raise your chair and add a footrest so your feet stay supported. If it is too low, sturdy risers under the legs are a cheap, reliable fix. When you are planning where a new desk will go, use our measuring guide and the Will It Fit planner so you get both the height and the footprint right before it arrives.

4. Positioning your monitor

Once your arms are happy, sort out your eyes and neck. The top of your screen should sit at, or just below, your seated eye level, so your gaze falls naturally onto the upper third of the display without tilting your head down or straining up. Push the monitor back to roughly an arm’s length away, about 50cm to 70cm, and adjust the tilt so the screen faces you squarely rather than reflecting the ceiling lights.

Laptop users are at a built-in disadvantage here, because a screen low enough to type on is always too low to look at. The fix is to raise the laptop on a stand or a stack of books until the top of the screen reaches eye level, then plug in a separate keyboard and mouse. If you run two monitors, place your primary screen directly in front of you and angle the second one in beside it, so you turn rather than twist to see it.

5. Keyboard and mouse placement

Wrist strain almost always comes from a keyboard that is too high, too far away, or propped up on its rear feet. Keep your keyboard flat, or even tilted very slightly down and away from you, so your wrists stay straight rather than cocked back. Your mouse belongs right beside the keyboard at the same height, close enough that you are not reaching out to the side and hitching your shoulder to get to it.

• Keep wrists floating in a straight line, not resting bent on a hard edge while you type.
• Use a soft wrist rest only as a pause spot between bursts of typing, not as a permanent perch.
• Position the keyboard centred on your body and the letter you use most, not on the desk edge.

If your desk is a touch high and you cannot lower it, a pull-out keyboard tray drops your hands into a neutral zone without changing the whole surface. A supportive seat pad can also lift you into a better arm position, and our cushion range is an easy way to fine-tune that last centimetre or two.

6. Quick height reference chart

Everyone is different, so treat these as sensible starting points and then fine-tune by feel using the joint angles above. The figures below assume a standard seated posture with feet flat and elbows at roughly 90 degrees.

If your natural height falls between two rows, start at the lower figure and raise things gradually, since it is easier to notice a surface that is a little too low than one that is quietly too high.

7. Sitting versus standing

A sit-stand desk lets you switch posture through the day, which relieves the pressure that builds from staying in any one position for hours. The heights are different, though. Standing, your desk should sit at about elbow height while you stand tall with relaxed shoulders, typically 95cm to 118cm depending on your build, as shown in the chart above. Your monitor still needs to rise with you so the top stays at eye level.

Standing all day is not the goal, and it brings its own aches if overdone. A gentle rhythm, alternating roughly every 30 to 60 minutes and moving little and often, beats any single fixed posture. Whether you sit, stand or swap between the two, the aim is the same: neutral joints and frequent movement. Our wider home office furniture guide walks through pairing the right desk, chair and storage for the way you actually work.

8. Small fixes that close the gap

Most people do not need to replace their furniture to feel better; they need to close small gaps between what they have and their ideal heights. The cheapest, most effective tweaks are:

• Footrest: if raising your chair leaves your feet dangling, a footrest, a sturdy box or even a ream of paper restores support and takes pressure off your thighs.
• Monitor riser: lift a too-low screen with a dedicated stand, a shelf or a few hardback books until the top reaches eye level.
• Desk risers: screw-in or slot-on leg risers add height to a desk that is too low, often the fastest fix for taller users.
• Seat cushion: a firm pad lifts you a couple of centimetres and adds support on a chair that is slightly too low or too hard.

Make one change at a time and give it a few days before judging it, because your body needs time to adapt to a new neutral. When you do decide to upgrade, a properly adjustable office chair earns its keep faster than almost any other purchase, and pairing it with the right desk from our home office collection removes the guesswork entirely.
