Many fixed desks are about 30 in (76 cm) high, but that common furniture height does not fit every person. The useful target is a keyboard and mouse surface near your seated elbow position with relaxed shoulders. Set your chair so your inputs are usable with elbows close to your sides, then support your feet. If raising the chair leaves your feet unsupported, add a footrest; if the input surface remains too high or low, use an adjustable desk or keyboard tray.
Standard versus adjustable desks
A fixed desk gives you one surface height, so the chair, foot support, and sometimes a keyboard tray must resolve the fit. A height-adjustable desk lets the work surface move to your seated or standing elbow position. Either can work; the difference is whether adjustment happens only around the desk or at the desk itself.
The elbow-height relationship
Fit is set at the elbows. With your chair adjusted so your feet are flat and thighs roughly parallel, your forearms should reach the desk with elbows near a right angle and shoulders relaxed β not hunched up or reaching down. Mayo Clinic and CDC/NIOSH guidance describes this same target. If your elbows are above the surface, the desk is low; if below, it's high. Measure by feel: type for a minute and notice your shoulders.
Chair-first correction
When the desk is fixed, adjust the chair and input position first. Raise or lower the seat only while you can keep the feet supported and the keyboard and mouse usable with relaxed shoulders. Then resolve any remaining foot-to-floor gap and check knee clearance. For the measurements to compare, see our chair-height guide and adjustable seat-depth guide.
Footrest use
Raising the seat to meet a tall desk can lift your feet off the floor. A footrest can fill that gap while your elbows stay at work-surface height. Choose a stable support that holds both feet without lifting your thighs or creating edge pressure.
Standing exceptions
For standing work, set the surface from your own standing elbow position rather than a generic height range. Keep shoulders relaxed, elbows close to the body, and the keyboard and mouse where your wrists can remain comfortable. Recheck after changing footwear or adding a mat.
Common mistakes and edge cases
- Chasing the desk number. Your elbow height matters more than the desk's height.
- Lowering the seat to reach the floor. Keep elbows at the desk and add a footrest instead.
- Ignoring shoulders. Hunched shoulders mean the desk is too high for your current seat.
- Very tall or short users. A height-adjustable desk may fit better than a fixed one.

FAQ
What is the standard desk height?
About 30 in (76 cm) is a common fixed-desk height, but it is not a universal ergonomic fit. Check the deskβs published dimension, then fit the chair, foot support, keyboard, and mouse to your own seated elbow position.
How do I know if my desk is the right height?
Set your chair for flat feet and parallel thighs, then check your elbows: they should meet the desk near a right angle with relaxed shoulders. Above the surface means the desk is low; below means it's high.
What if my desk is too high?
Raise the chair until your elbows are at desk level, then add a footrest so your feet are supported. A keyboard tray can also lower your effective work surface.
What height should a standing desk be?
Set it from your standing elbow position: shoulders relaxed, elbows close to your body, and the input surface at a height that lets your wrists remain comfortable. Recheck the setting in your usual footwear.
