Adjust Your Monitor to Eye Level

The top of your monitor should sit at or just below eye level when you are sitting upright with your shoulders relaxed. If your screen is too low, you will lean forward and strain your neck and upper back over hours of work. If it is too high, you will tilt your head back, which creates tension in the back of your neck and shoulders.

Measure the distance from your eyes to the screen: it should be about 20 to 26 inches (roughly an arm's length). If your monitor is built into a laptop, use a separate keyboard and trackpad, then raise the laptop on a stand or stack of books so the screen reaches eye level. A monitor arm that clamps to your desk gives you the most flexibility to adjust height and angle without taking up desk space.

Tilt the top of the screen slightly away from you—about 10 to 20 degrees—so you are looking slightly downward rather than straight ahead. This angle reduces glare and matches the natural downward gaze of relaxed eyes.

Key Takeaways

  • Your monitor should sit at eye level when you sit upright, roughly 20 to 26 inches from your eyes, to prevent neck and shoulder strain.
  • Your keyboard and mouse should be at elbow height with your arms at a 90-degree angle, so your wrists stay neutral and straight.
  • Your chair seat should be high enough that your thighs are parallel to the floor and your feet rest flat, with your lower back supported by a cushion if needed.
  • Take a 5-minute break every hour to stand, stretch, and look away from the screen to reduce eye fatigue and muscle tension.
  • A document holder, wrist rest, and footrest are low-cost additions that reduce strain if you spend more than four hours a day at your desk.

Position Your Keyboard and Mouse at Elbow Height

Your keyboard and mouse should sit at a height where your elbows bend at roughly 90 degrees when your arms hang naturally at your sides. If they are too high, your shoulders will hunch up toward your ears. If they are too low, you will lean forward and round your upper back.

Your wrists should be straight and neutral—not bent upward, downward, or to the side—when you type or move the mouse. A keyboard tray that slides under your desk and adjusts up and down makes this easier than a fixed desk surface. If you cannot adjust the desk itself, a keyboard tray costs $30 to $80 and attaches with a clamp.

Keep your mouse close to your keyboard, at the same height, so you do not reach or twist your arm to use it. A mouse pad with a built-in wrist rest ($15 to $40) reduces strain if you move the mouse frequently throughout the day.

Choose a Chair That Supports Your Lower Back

Your chair seat should be high enough that your thighs are parallel to the floor and your feet rest flat on the ground or a footrest. If the seat is too high, your feet will dangle and put pressure on the backs of your thighs. If it is too low, your knees will be higher than your hips and you will slouch.

The backrest should support the natural curve of your lower spine (called the lumbar curve). Many office chairs have a lumbar support adjustment—a dial or lever that moves a cushioned bump forward or backward. If your chair does not have one, a small pillow or lumbar roll ($20 to $50) placed behind your lower back does the same job.

Sit with your back against the chair, not perched on the edge. Your shoulders should be relaxed, not hunched forward or pulled back. If you find yourself slouching after 30 minutes, the chair may not be right for your body, or you may need a footrest to change the angle of your hips.

Use a Footrest if Your Feet Do Not Reach the Floor

If you are shorter than average or your desk is high, a footrest keeps your feet from dangling and your legs from going numb. A footrest should be 4 to 6 inches high and wide enough for both feet. It costs $25 to $60 and attaches to the floor or sits freely under your desk.

When your feet rest on a footrest, your thighs stay parallel to the floor and your lower back stays in contact with the chair. This small change reduces pressure on your lower spine and prevents your legs from falling asleep during long work sessions.

Add a Document Holder and Reduce Screen Glare

If you type from printed pages or reference documents while you work, a document holder ($15 to $40) clips to the side of your monitor at the same height and distance as your screen. This keeps your neck from twisting back and forth between the page and the monitor, and prevents you from looking down at papers on your desk.

Glare on your screen forces your eyes to work harder and can cause headaches. Position your monitor perpendicular to windows so light does not reflect off the screen. If that is not possible, close blinds during the brightest part of the day or use a matte screen protector ($10 to $20). Reduce the brightness of your monitor to match the light in the room around it—a screen that is brighter than your surroundings strains your eyes.

Take Breaks and Move Throughout the Day

Even the most ergonomic setup cannot replace movement. Every hour, stand up, walk for a few minutes, and look away from the screen at something at least 20 feet away. This gives your eyes a chance to refocus and your muscles a chance to reset.

Stretch your neck, shoulders, wrists, and lower back for 30 seconds at a time. Roll your shoulders backward, tilt your head gently to each side, and make circles with your wrists. These straightforward movements take less than five minutes and prevent the stiffness that builds up during long sitting sessions.

If you spend more than six hours a day at your desk, consider a standing desk converter ($100 to $300) that lets you raise your monitor and keyboard to standing height for part of the day. Alternating between sitting and standing every 30 to 60 minutes reduces strain on any single set of muscles.

Frequently Asked Questions

What is the best desk height for an ergonomic setup?

A desk should be high enough that your elbows bend at 90 degrees when your arms hang at your sides and your hands rest on the keyboard. Standard desk height is 28 to 30 inches, which works for most people of average height. If you are much taller or shorter, a keyboard tray that adjusts independently of the desk gives you more control.

Do I need to buy an expensive ergonomic chair?

A chair does not have to be expensive to be ergonomic. Look for one with a seat that adjusts up and down, a backrest that supports your lower spine, and armrests (or the ability to remove them). A basic office chair with these features costs $150 to $300. A lumbar pillow ($20 to $50) can improve almost any chair you already own.

How far should my monitor be from my eyes?

Your monitor should be about 20 to 26 inches from your eyes—roughly the distance from your elbow to your fingertips when your arm is extended. If you wear bifocals or progressive lenses, you may need to sit slightly closer so you can see the screen through the reading portion of your glasses.

Can I use a laptop as my main computer without hurting my neck?

A laptop screen is usually too low to use without a separate keyboard and monitor stand. If you use a laptop for more than two hours a day, raise it on a stand and use an external keyboard and mouse. This costs $30 to $100 total and prevents the forward head posture that laptops force.

What should I do if I still have pain after making these changes?

Pain that does not improve after two to three weeks of ergonomic adjustments may be a sign of an underlying condition. A physical therapist or occupational therapist can assess your specific setup and suggest changes tailored to your body. Many insurance plans cover these visits with a doctor's referral.
