On carpet, set a standing desk on firm, flat support and treat pile above about 12 mm as a stability problem; on hard flooring, focus on leveling feet, scratch protection, and slip control instead of extra support depth.
Set the top edge of the screen at eye level, or 1 to 2 inches below it, with the display about an arm’s length away, about 20 to 30 inches for many desks.
A dual monitor workspace on a standing desk starts with 60 to 75 cm of desk depth, a mount rated at least 20% above each monitor’s actual weight, and screens placed so the top edge sits at or just below eye level.
Use a 30- to 45-minute standing block, then take a 30- to 60-second stretch break with 2 to 4 movements, each held for 15 to 20 seconds at a mild 2 to 3 out of 10 intensity.
Keep a standing desk stable on a wobble-prone floor by leveling each foot, spreading the load on a rigid base, and keeping floor deflection under about 2.
Use a standing desk for deep work in 30- to 60-minute blocks, keep the monitor top at or just below eye level, and hold elbows near 90 degrees. That setup works best when the task is planning, reading, drafting, or review.
Set the desk so your elbows sit near 90 degrees, the monitor top lands at or slightly below eye level, and the desktop is at least 24 inches deep, about 61 cm, or 30 inches, about 76 cm, if a monitor arm and keyboard share the same surface.
Set the upper limit 1 to 2 inches, or 25 to 50 mm, below the lowest fixed obstruction and the lower limit 1 inch above the lowest point the desk crosses on the way down. Use the larger gap when shelves, lights, blind hardware, or a window trim sit inside the travel path.
A daily standing desk posture checklist starts with elbows at 90 to 110 degrees, the monitor top at or slightly below eye level, wrists neutral, and both feet fully supported.
