How to set a standing desk to the right height
There is no correct number in inches. There is a correct position for your body, and once you know how to find it, setting the desk takes about a minute — and you will probably find you have been sitting an inch too high for years.

What height should a standing desk be?
Set the desktop so your elbows sit at about 90 degrees with your shoulders relaxed and your forearms roughly parallel to the floor. That is the whole rule, and it produces two different numbers for the same person: one for sitting, one for standing.
Measure it from your own body rather than copying a figure. Elbow height varies with torso length, not just overall height, which is why two people of the same height can need desks set an inch apart. Charts giving a single "correct" desk height by your height in feet and inches are guessing at that.
Find your seated height
Sit up straight in the chair you actually use, feet flat on the floor. Let your arms hang, then bend the elbows to 90 degrees and hold them there. That forearm height is your seated desktop height. Set the desk to it, then check: hands on the keyboard, shoulders down, no shrug.
If your shoulders ride up, the desk is too high. If you find yourself hunching down toward the keyboard, it is too low. Both feel fine for ten minutes and hurt after two hours, which is why the shoulder check matters more than how it feels immediately.
Find your standing height
Same test standing up. Stand naturally — not on tiptoe, not slouched — let your arms hang, bend to 90 degrees. That is the standing desktop height. Save it as a preset if your desk has memory positions, because you will not want to re-find it every morning.
The seated and standing numbers are typically several inches apart, and that gap is exactly why the height range on a desk matters more than the maximum. A desk that reaches 50" is useless to you if it cannot come down to your seated height — which is the single most common reason a tall desk gets returned.
Where should the monitor go?
Top of the screen at or just below eye level, so you look slightly down at the middle of the display without tilting your head. Roughly an arm's length away, and straight ahead rather than off to one side.
This is the setting people get wrong most often on a rising desk. A monitor on its own stand is fixed at one height, so it is correct in at most one of your two positions — usually the seated one, which means you spend your standing hours looking down at a screen that is too low. That is the argument for a monitor arm, which lets the screen travel with the desk rather than staying put.
If you use a laptop without an external screen, this does not apply cleanly: a laptop screen cannot be raised independently of its keyboard. That is the case where an external monitor plus a stand or arm is not a luxury but the only way to get both your keyboard and your screen at the right heights at once.
The mistakes that cause the pain
Four of them, and they account for most "my standing desk hurts" complaints: desk too high, monitor too low, keyboard too far away, and standing still for too long. None is fixed by buying a better desk.
1. Desk too high — shoulders, not wrists
A desk that is even an inch too high shows up as neck and shoulder tension, because you shrug to reach the keyboard. People often blame the chair. Check the desk first: shoulders down, elbows at 90, and if you cannot get there, the desk is the problem.
2. Monitor too low — the neck one
Looking down at a screen for hours loads the neck. On a standing desk this usually means the monitor stayed at seated height while the desk went up, so check the screen position in both positions, not just one.
3. Keyboard too far away
If you reach forward for the keyboard, your shoulders come forward with it and the desk height stops mattering. The keyboard should sit close enough that your elbows stay tucked near your sides.
4. Standing still
Standing is a different posture, not exercise. Locking your knees and staying perfectly still for an hour is worse than sitting properly for an hour. Shift your weight, and sit down when you feel like it rather than when a timer tells you to.
How often should you switch?
There is no single correct interval. Anything specific you read quoted as the right number is a starting point, not a rule — and we are not going to invent one here, because we have not verified one.
What matters more than the interval: change position before discomfort starts rather than after, and treat standing as one option among several rather than the goal. The point of a sit-stand desk is that you are not stuck in one posture, not that you should be standing as much as possible.
What if the desk will not go low enough?
Fit an under-desk keyboard tray. It drops the working surface to seated elbow height without replacing the desk, and gives back desk depth at the same time. It is the cheapest real fix, and it suits renters because a clamp-on tray needs no drilling.
Needs about 31.3" of clear width under the desk, and will not clamp to a crossbar or a curved edge.
Check two things first, because they disqualify most trays: you need about 31.3 inches of clear width underneath, and the desk must not have a crossbar running across that space. A curved or bevelled front edge will also defeat a clamp. If your desk fails any of those, the honest answer is that the desk itself is the wrong height range for you — which is a buying problem, not an accessory problem.
Why the height range on the box matters more than the maximum
Because the number that decides whether a desk fits you is the bottom of the range, not the top. Marketing leads with maximum height. The specification that actually disqualifies a desk is the minimum: if it cannot come down to your seated elbow height, you will be uncomfortable every time you sit, which for most people is most of the day.
Two-stage legs typically start around 28". Three-stage legs start lower — across the frames we track, somewhere between about 22.6" and 25" depending on the model. That gap of several inches is the whole reason three-stage frames exist, and it matters if you are shorter: a two-stage desk bottoms out above your seated elbow height, and no accessory fully fixes that.
We covered this in detail in our standing desk comparison, where height range is one of the four specs we use to judge a frame. If you are choosing a desk now, check the minimum height against your seated elbow before you look at anything else on the listing.
Frequently asked questions
What height should a standing desk be?
Set the desktop so your elbows sit at about 90 degrees with your shoulders relaxed and your forearms roughly parallel to the floor. That is the whole rule, and it produces two different numbers for the same person: one for sitting and one for standing. Measure it from your own body rather than copying a figure, because elbow height varies with torso length, not just overall height.
How do I know if my desk is too high?
Your shoulders ride up when you rest your hands on the keyboard, or you find yourself shrugging while typing. That is the reliable tell, and it shows up as neck and shoulder tension rather than wrist pain. If the desk cannot go lower, an under-desk keyboard tray is the cheapest way to drop the working surface to the right height.
Should my monitor be at eye level?
Roughly, yes — the top of the screen at or just below eye level, so you look slightly down at the middle of the display without tilting your head. On a rising desk this is the setting people get wrong most often, because a monitor on its own stand is fixed at one height and is therefore wrong in either the sitting or the standing position.
How often should I switch between sitting and standing?
There is no single correct interval, and any specific number you see quoted should be treated as a starting point rather than a rule. What matters more than the interval is that you change position before discomfort starts rather than after, and that standing is not treated as exercise — it is just a different posture.
What should I do if my standing desk will not go low enough?
Fit an under-desk keyboard tray. It drops the working surface to seated elbow height without replacing the desk, and recovers desk depth at the same time. Check your desk has about 31.3 inches of clear width underneath and no crossbar, because those are the two things that disqualify a clamp-on tray.
