Standing Desk & Chair Height Calculator
Enter your height to calculate your exact standing desk height, sitting elbow position, chair seat elevation, and monitor eye level using official BIFMA G1-2017 ergonomic standards.
Your Exact Ergonomic Setup Measurements
Height of desktop surface. Forearms should rest horizontal with elbows at a relaxed 90°–100° angle.
Standard fixed desks are 29"–30". If your target is below 28", you need an adjustable desk or footrest.
Distance from top of seat cushion to floor. Feet should plant completely flat with thighs parallel to floor.
Top 1/3 of your display should align directly with your horizontal eye line at ~20"–28" viewing distance.

How Standing Desk Height Formulas Actually Work
Most standing desk pain occurs because people set their desk too high. When your desk is elevated past your natural standing elbow height, your shoulders shrug up to reach the keyboard. After 45 minutes, that causes trapezius tension and upper back tightness.
The correct ergonomic posture follows the 90-degree forearm rule: with your shoulders relaxed and elbows at your sides, your forearms should extend forward parallel to the floor or angled slightly downward (up to 100°). The keyboard and mouse should sit directly beneath your hands without bending your wrists backward.
The 20-8-2 Golden Rhythm
Standing all day is almost as bad as sitting all day. Research from Cornell University recommends the 20-8-2 formula for a healthy workday:
- 20 Minutes: Sitting in an ergonomic, supported position.
- 8 Minutes: Standing at your calculated standing desk height.
- 2 Minutes: Moving, stretching, or walking.

Frequently Asked Questions
Should I calculate desk height with or without shoes?
Always calculate with shoes if you wear shoes or sneakers at your desk. Regular sneakers add 0.75" to 1.25" to your height. If you use a gel anti-fatigue mat barefoot, add 0.75" to account for the mat thickness.
Why does a fixed 29-inch desk cause neck and shoulder pain?
Standard commercial desks are built at a fixed 29" to 30" height to accommodate the 95th percentile of adult men. For anyone under 6'0", a 29" sitting desk is too high, forcing your arms up and raising your shoulder blades.
How do I measure screen distance?
Sit back in your chair with your back resting against the lumbar support. Extend your arm straight forward with fingers extended. Your fingertips should barely touch the center of your monitor screen (~20" to 28" distance).
