Two numbers decide whether a desk fits you, and almost nobody works them out before buying. It takes about ninety seconds, and it will disqualify some of the desks you were considering.
Your standing desk height is your standing elbow height: stand upright, relax your shoulders, bend your elbows to 90 degrees, and measure from the floor to the underside of your forearm. Your seated height is the same measurement done sitting, with your feet flat and thighs parallel to the floor. If you are buying a frame rather than a finished desk, subtract your desktop thickness from both.
Work it out
Standing desk height calculator
Enter your height and the thickness of your desktop. These are estimates from stature — if you can, measure your actual elbow height instead and use that. The tool will still do the desktop correction for you.
Your numbers
Standing desk height
43.5"
Frame must reach 42.5" before the top goes on.
Seated desk height
28"
Frame must drop to 27".
Top of your screen, standing
about 65" from the floor
Roughly eye level. If your desk is at elbow height, a monitor arm is usually how you reach this.
Estimates for a 5'10" user, from stature. Elbow height varies by several inches between people of the same height — how we work.
Better: measure it properly
The calculator estimates from stature, and stature is a rough proxy. Two people who are both 5'10" can have elbow heights three inches apart, because torso and leg proportions differ. Measuring takes a minute and beats any formula.
Standing
Stand upright, in the shoes you actually work in.
Let your shoulders drop. Do not hold them up — that is the posture you are trying to avoid.
Bend your elbows to about 90 degrees, forearms parallel to the floor.
Measure from the floor to the underside of your forearm.
Seated
Sit in the chair you actually use, at the height you actually use it.
Feet flat on the floor, thighs parallel to it. If your feet dangle, lower the chair first.
Same relaxed shoulders, same 90-degree elbows.
Measure from the floor to the underside of your forearm again.
Do both at once
Those two numbers are the only two presets you will ever need on a sit-stand desk. Set them on day one and the desk gets used; leave it on up-and-down buttons and it does not.
The desktop thickness trap
This is where buyers lose an inch without noticing. Some makers publish a frame range, some publish a finished desk range, and some converters publish a lift measured above your existing desk. Three different measurements, quoted the same way.
Which number are you reading?
Type
Example
What to do with it
Frame range
UPLIFT V3: 22.6" – 48.7"
Add your desktop thickness to both ends
Finished desk range
Vari Electric: 25" – 50.5" with a 1.25" top
Use as-is
Converter lift
VariDesk Pro Plus 36: 4.5" – 17.5"
Add your existing desk height
A 1" top turns a 48.7" frame into a 49.7" desk. That helps a tall user and hurts a short one, because it lifts the floor of the range too.
Check it against real desks
Now take your two numbers and check them against the published ranges. This is the step that makes the exercise worth doing — it usually eliminates something.

If your seated number is below 25", four of those seven are out — the short-user problem. If your standing number is above 48.7", three of them are out — the tall-user problem.
For converters, add your existing desk height instead: the converter arithmetic. And if you are putting a walking pad under the desk, add another 5 to 6 inches to your standing number before you check anything.
Then set the screen
Desk height is set by your elbows. Screen height is set by your eyes, and the two are independent — which is the single most useful thing to understand about ergonomic setup.
Aim for the top of the screen at roughly eye level, or a little below. If your desk is at elbow height and your monitor is on its factory stand, the screen will usually be too low, and no amount of desk adjustment fixes that. A monitor arm is how you separate them.
Desks with the widest range
From the picks
If your numbers are awkward
Two desks with the lowest floors we found, and the clamp-on converter for people whose standing number is above what any platform reaches.
The V2's replacement, and the one that will actually be in stock. UPLIFT puts the range at 22.6" to 48.7" — a lower floor than the V2, which matters more than the ceiling for most people — on the same 355 lb rating and 15-year warranty.

The default recommendation for a reason: the same 355 lb rating and the same 15-year warranty as UPLIFT, at a price that usually lands a tier below, with the desktop already included.

8.5 /10
Researched, not personally tested
A clamp-on arm rather than a platform, so it takes no desk depth at all and lets the monitor move independently of the keyboard. For tall users that independence is the whole argument.
What height should a standing desk be for a 5'10" person?+
Typically around 42" to 44" standing and 27" to 29" seated — but elbow height varies by several inches between people of the same stature. Measure rather than rely on the estimate.
Should the desk be at elbow height exactly?+
Elbow height or very slightly below, with shoulders relaxed. Slightly below is generally more comfortable than slightly above, because too-high forces the shoulders up.
Do I measure with shoes on?+
With whatever you actually wear at the desk. An inch of shoe is an inch of desk height.
What if I share the desk?+
Take both people's numbers and buy for the wider span — usually that means the lowest seated height and the highest standing height. Presets make sharing workable.
