The best height for a standing desk isn’t a number you look up — it’s a number you measure off your own body, and it takes thirty seconds. This is our long-running height guide, refreshed for 2026: the elbow rule, the sitting and standing targets, and the monitor math that finishes the job.
The rule that decides everything: elbow height
Stand relaxed, shoulders down, upper arms hanging naturally, forearms parallel to the floor — the height of your elbows is your standing desk height. Set the desktop so your hands rest on the keyboard with elbows at roughly 90 degrees and wrists straight. That single measurement outranks every chart, because arm proportions vary even between people of identical height.
Quick reference numbers
For orientation only: a person around 5’7″ typically lands near 41 to 43 inches standing; add or subtract roughly an inch per inch of body height. Sitting, the same elbow rule gives most people 27 to 29 inches — which is why fixed 29-inch office desks run tall for average and shorter users. Petite users should check a desk’s minimum height before buying (our petite standing desk guide lists frames that drop to 22 inches), and tall users the maximum (see the tall-person guide — three-stage frames buy the most range).
Setting the height while sitting
Same elbows, seated: chair adjusted so feet sit flat and knees near 90 degrees first, then the desk down to meet your forearms. If the desk can’t come down far enough, raise the chair and support your feet — the footrest fixes what the furniture won’t. The chair half of the equation matters as much as the desk; the under-$500 chair rankings cover it.
The monitor completes the calculation
Desk height positions your arms; monitor height positions your neck. Top of the screen at or just below eye level, an arm’s length away, with a slight upward gaze angle to the center of the display. Laptop users need a riser or arm plus external keyboard — a laptop flat on a perfectly calculated desk still wrecks the neck math.
Keep adjusting — comfort is a moving target
Shoes on or off, thick mat or bare floor, even the keyboard’s thickness shift your ideal by fractions of an inch — which is the quiet argument for electric desks with memory presets: measure once, save, and the right height becomes one button. Recalculate whenever anything changes, and if you’re still choosing the desk itself, the best standing desks rankings and small-space guide hold the current verified field.
