Set the desk so your elbows rest at about 90 degrees with your forearms parallel to the floor and shoulders relaxed — for most adults that is 38 to 47 inches, and roughly 42 to 44 inches for someone 5 feet 10 inches tall. A quick estimate is about 60 percent of your standing height. Then check the monitor separately: the top of the screen should sit at or just below eye level, about an arm length away. Adjust in one-inch steps after typing for a few minutes rather than trusting the first number.
What height for my height?
These are starting figures derived from the elbow rule, measured to the top of the desk surface. Your own comfortable height can sit an inch either side of the range depending on shoe height and keyboard thickness.
| Your height | Standing desk height | Sitting desk height |
|---|---|---|
| 5 ft 0 in | 35–37 in | 23–24 in |
| 5 ft 4 in | 39–40 in | 25–26 in |
| 5 ft 8 in | 41–43 in | 27–28 in |
| 5 ft 10 in | 42.5–44 in | 28–29 in |
| 6 ft 0 in | 44–45 in | 29–30 in |
| 6 ft 2 in | 45–47 in | 30–31 in |
Note how far the standing figures spread. That range is exactly why the frame you buy needs to cover your number — many budget frames stop around 45 inches, which leaves taller users permanently a little low.

How do you find your own number?
Forget the chart for a moment and use your body. Stand upright with your shoulders down and relaxed, arms at your sides, then bend your elbows to a right angle so the forearms are level. The height of your forearms is the height of your keyboard, and therefore the desk. Two refinements matter. First, measure in the shoes you actually wear at that desk, since a work boot and a bare foot differ by more than an inch. Second, if you use a thick mechanical keyboard, drop the desk slightly so your wrists stay flat rather than cocked upward. Type for ten minutes and adjust an inch at a time; comfort at minute ten tells you more than a tape measure.

What goes wrong at the wrong height?
Too high is the more common and the more punishing error. The desk pushes your shoulders into a permanent shrug and forces the wrists to extend upward over the keyboard, which produces neck, shoulder and wrist discomfort within an hour or two. People rarely blame the height — they blame standing, and then stop using the feature. That is the single biggest reason standing desks go unused, which is worth knowing before you buy one at all; the honest cost-benefit is in are standing desks worth it. Too low is less damaging but leads to hunching and leaning on the desk edge. If you find yourself resting your weight on your forearms, the surface is low.

Where does the monitor go?
Screen height is a separate adjustment from desk height and it is the one people skip. Put the top of the screen at or just below eye level and set it roughly an arm length away, about 20 to 30 inches. Because the monitor rides up with the desk, a setup that was right seated is usually right standing — but check your head angle, since many people unconsciously look down. Laptop users need a riser or an external display: a laptop screen sitting flat on a standing desk puts the neck in a sustained forward bend for the whole session. If you use a monitor arm, set it once for standing and once for sitting.
Save both heights
Program your sitting and standing numbers into the desk memory presets. A one-touch switch removes the friction that otherwise stops people from alternating — and alternating, not standing, is what the schedule in how long to stand at a standing desk is built around. Presets are a common dividing line between frame tiers, and stability at full extension is another; both are covered in single versus dual motor desks and our standing desk picks.
