Best desk height for a 5′6″ (168 cm) person
Estimate a seated desk and chair starting point for someone 5′6″ tall, then refine it from elbow height, foot support, keyboard thickness, and real tasks.Quick answer
Desk-height starting point for 5′6″
A broad proportional estimate is about 27.7 in (70 cm) for the seated input surface and 17.2 in (44 cm) for seat height. These are setup starting points, not body-specific prescriptions.
A practical framework
Work through the decision in a visible order.
Start with chair and foot support
At 5′6″, the 17.2-inch estimate is only a first chair setting. Adjust until the feet are supported, the knees are comfortable, and the seat edge does not concentrate pressure behind the thighs.
Match the desk to relaxed elbows
The 27.7-inch estimate should be checked while typing and pointing. If a fixed desk is high, raise the chair only with stable foot support or consider a keyboard tray; if low, use a stable riser or adjustable surface.
Sitting and standing are different presets
Do not reuse the seated number for standing. Set the standing input surface from actual standing elbow height, keep the screen readable, and use standing as one position among several rather than a full-day target.
Test the whole workstation
Work for twenty to thirty minutes, note reaching, shoulder lift, thigh pressure, leaning, glare, and discomfort, then change one variable. Persistent, severe, spreading, or neurological symptoms need qualified assessment.
Action checklist
Before you consider the task complete
- Support both feet or use a stable footrest.
- Keep shoulders relaxed and elbows near the body.
- Place keyboard and pointer at the same reachable level.
- Set monitor distance and height after the input surface.
Common questions
Questions this guide should answer
Is 27.7 inches the exact desk height for 5′6″?
No. Body proportions and the effective input height vary. Use the estimate to begin, then fit the workstation to supported feet, relaxed shoulders, comfortable elbows, reach, and task.
Do I need a footrest?
Use one when the chair must be raised for the desk and the feet no longer rest securely. It should be stable, large enough, and should not block position changes.
