Desk Height Calculator
Optimize your workspace for better posture and productivity.
Calculations follow standard ergonomic guidelines for a 90-degree elbow and knee bend.
Your Ideal Setup
Note: These are starting points. Adjust slightly until your elbows are at 90° and feet are flat on the floor.
The Science of Ergonomics: Why Desk Height Matters
In 2026, with the majority of work being digital, ergonomics has shifted from a luxury to a health necessity. An incorrectly sized desk or chair is the leading cause of Repetitive Strain Injury (RSI), chronic back pain, and neck stiffness. Our Desk Height Calculator uses anthropometric data to align your furniture with your body's natural proportions.
How Ergonomic Heights are Calculated
The formulas are based on maintaining neutral body positions. A "Neutral Position" means your joints are naturally aligned, reducing stress on the muscles and tendons.
1. Sitting Desk Height Formula
Ideally, your elbows should be at a 90-degree angle when typing. We use the following ratio based on total stature:
2. Standing Desk Height Formula
When standing, the desk should be at the level of your resting elbows:
Key Factors for the Perfect Setup
- The 90-Degree Rule: Your elbows, hips, and knees should all ideally form 90-degree angles.
- Eye Level: The top third of your monitor should be at eye level. This prevents you from tilting your head up or down, which strains the cervical spine.
- Feet Placement: Your feet must be flat on the floor. If your chair is too high to achieve this after adjusting for your desk, use a footrest.
