Set Your Table Height So Your Elbows Bend at 90 Degrees
The most common mistake is a table that sits too high or too low. Your desk should position your elbows at a right angle when your arms rest naturally at your sides and your hands rest on the keyboard. If your elbows point downward at an angle steeper than 90 degrees, the table is too high. If they point upward, the table is too low.
To find the right height, sit in the chair you actually use for work — not a different one — with your feet flat on the floor. Let your arms hang naturally. Measure from your elbow to the floor. That measurement is your target desk height. Standard office tables are 28 to 30 inches tall, which works for people roughly 5'8" to 6' tall. If you are shorter or taller, you may need to raise or lower the table.
If your table is fixed height and does not match your body, use a footrest to raise your feet (which lowers your effective elbow height relative to the desk) or add risers under the table legs to raise the whole surface. Adjustable-height tables let you change the height without tools, though they cost more upfront.
Key Takeaways
- Your elbows should form a 90-degree angle when your hands rest on the keyboard, with your feet flat on the floor.
- Measure from your elbow to the floor while sitting in your actual work chair to find the correct table height for your body.
- Position your monitor directly in front of you at arm's length, with the top of the screen at or slightly below eye level.
- Keep your wrists straight and parallel to the floor when typing; use a keyboard tray or wrist rest if your table height forces your wrists to bend.
- Adjust your chair first, then adjust the table or use risers and footrests to match — never adjust your posture to fit the furniture.
Position Your Monitor at Arm's Length and Eye Level
Your monitor should sit directly in front of you, not off to one side. Measure the distance from your eyes to the screen: it should be roughly an arm's length away, or 20 to 26 inches. Too close causes eye strain; too far forces you to lean forward or squint.
The top of the monitor should be at or slightly below eye level. If you wear bifocals or progressive lenses, you may need the screen lower so you can see it through the reading portion of your lenses without tilting your head back. Adjust the monitor height using a monitor stand, arm, or stack of books under the base. Never crane your neck down to look at a screen that sits too low, and never look up at one that sits too high.
If you use a laptop, the keyboard is too low and the screen is too high when used together. Use an external keyboard and mouse, and raise the laptop on a stand so the screen reaches eye level. This is one of the most common sources of neck and shoulder pain in remote work.
Keep Your Keyboard and Mouse at the Same Height as Your Elbows
Your keyboard and mouse should sit at the same height as your elbows when your arms are at rest. This keeps your wrists straight and parallel to the floor while you type. If the keyboard is higher than your elbows, your wrists bend upward, which can lead to repetitive strain injury over time. If it is lower, you hunch your shoulders.
Most people rest their keyboard directly on the desk surface, which works if the desk height is correct. If your desk is too high for your body, a keyboard tray that mounts under the desk can lower the keyboard without lowering the whole table. Keyboard trays slide in and out and tilt, so you can fine-tune the angle. A wrist rest — a padded bar in front of the keyboard — supports your wrists during typing and can reduce strain if you type for long hours.
Your mouse should sit at the same height as your keyboard, right next to it. If you reach across the desk or up to a shelf for the mouse, you twist your shoulder and arm. Keep both input devices close and level.
Adjust Your Chair Before You Adjust the Table
Start with your chair, not the table. A good work chair has a seat height you can adjust, a backrest that supports the curve of your lower spine, and armrests (or the ability to remove them). Sit in the chair with your feet flat on the floor. Your thighs should be parallel to the floor, not tilted up or down. If your feet do not touch the floor, use a footrest.
Once your chair height is set, measure your elbow height and adjust the table to match. Many people try to fix posture by changing the table and then wonder why their back still hurts — the problem was the chair all along. A chair that does not support your lower back or forces your thighs to angle upward will cause pain no matter how perfect the table height is.
If your chair has armrests, they should be low enough that your elbows rest on them without your shoulders hunching up. Some people remove armrests entirely if they get in the way of the desk or keyboard tray. That is fine as long as your chair back supports your arms indirectly by supporting your torso.
Create Space for Your Legs and Feet Under the Table
Your knees and shins need clearance under the table. Sit in your chair and slide it all the way under the desk. Your knees should not touch the underside of the table, and you should be able to cross your legs or shift your position without hitting the table frame or any cables.
If your table has a thick frame or a shelf that blocks your legs, you may need to move the chair back slightly, which increases the distance from your eyes to the monitor. This is a trade-off: a little extra distance to the screen is better than cramped legs that force you to sit in an awkward position. If leg room is very tight, consider a table with a thinner frame or an open design that does not have a center support.
Keep cables and power strips out of the way so they do not catch your feet or force you to sit at an angle to avoid them. A cable management tray or clips can route wires along the back or underside of the table.
Use a Document Holder and Organize Your Desk to Reduce Neck Strain
If you type from paper documents, a document holder mounted next to your monitor keeps the page at the same height and distance as your screen. Without one, you look down at the desk, then back up at the monitor, then back down — this constant neck movement causes fatigue and pain.
Organize your desk so the things you use most often are within arm's reach and at eye level or slightly below. Your keyboard and mouse should be closest. Reference materials, notepads, and phones should be within a few inches. Rarely used items can go in drawers or shelves farther away. This reduces the amount of reaching and twisting you do throughout the day.
Keep your desk clear of clutter. A cluttered surface forces you to move things around, reach across obstacles, or lean forward to find what you need. A clean desk also makes it easier to notice when something is out of position — like a monitor that has drifted to one side.
Check Your Setup Every Few Weeks and Adjust as Needed
Furniture settles, monitors drift, and your body changes. Every few weeks, sit at your desk and check the basics: Are your elbows at 90 degrees? Is your monitor at eye level? Are your wrists straight? Small adjustments prevent problems from building up.
If you start to feel neck, shoulder, or wrist pain, do not wait for it to go away on its own. Stop and check your setup. The pain is usually a sign that something is out of position. Adjust the table, monitor, or chair, and see if the pain improves over the next few days. If it does not, consider adding a wrist rest, footrest, or document holder.
Take breaks every 30 minutes to stand, stretch, and look away from the screen. Even a perfect setup cannot replace movement. Sitting in one position for hours, no matter how ergonomic, causes stiffness and fatigue.
Frequently Asked Questions
What if my table is too high and I cannot lower it?
Use a footrest to raise your feet, which effectively lowers your elbow height relative to the desk. A footrest also gives your feet a place to rest and can reduce pressure on your lower back. If a footrest alone does not solve the problem, add risers under your chair legs to raise the whole chair, or use a keyboard tray to lower just the keyboard.
Can I use a standing desk instead of a sitting desk?
Yes, but standing all day is not better than sitting all day. The best setup is one you can change throughout the day. An adjustable-height desk lets you sit for a few hours, then stand for a few hours, then sit again. If you use a fixed standing desk, use an anti-fatigue mat under your feet and take sitting breaks every hour or so.
How do I know if my monitor is at the right distance?
Sit in your chair and extend your arm straight out in front of you. Your fingertips should almost touch the monitor screen. That is roughly 20 to 26 inches, which is the standard comfortable viewing distance. If the screen is farther away, you may lean forward or squint. If it is closer, you may experience eye strain.
Should I use a wrist rest while typing?
A wrist rest supports your wrists between typing bursts, not while you are actively typing. Your wrists should float above the keyboard while your fingers move. Rest your wrists on the pad when you pause to read or think. This reduces the strain on your wrists and forearms during long work sessions.
What is the best type of chair for desk work?
Look for a chair with adjustable seat height, a backrest that supports your lower spine, and a seat that is not too soft or too firm. Armrests are helpful but not essential if the backrest is good. Test the chair before you buy it — sit in it for at least five minutes and check that your feet touch the floor and your thighs are parallel to the ground.
