A precise architectural blueprint for your home office setup.

Architecture of the Human Chassis

Most developers work in environments designed for the “Average User”—a statistically non-existent person who is 5’9”, male, and sits perfectly upright. If you deviate from this template by even two inches (height-wise), standard desk heights (typically 29 inches) become biologically hostile.

Working at a desk that is mathematically misaligned with your humerus and femur length creates “Hardware Compatibility Issues” in your body. Shrugged shoulders leads to Trapezius Myalgia. Typing with flexed wrists leads to Carpal Tunnel. This tool calculates the precise 90-90-90 Neutral Position coordinates for your unique skeleton.

The 90-90-90 Rule

The gold standard in occupational biomechanics is orthogonality.

Elbows: 90° angle (Forearms parallel to floor).
Hips: 90-100° angle (Open hip angle reduces compression).
Knees: 90° angle (Feet flat on floor).

Achieving this requires a variable-height desk. Most fixed desks are too high for typing but too low for monitors, forcing a compromise.

The “Monitor Arm” Factor

The single most common error in developer setups is screen height. Your eye level should align with the top third of your primary monitor. Why? Because looking UP dries out the cornea (by widening the eyelid aperture) and extends the neck. Looking DOWN increases cervical load (Text Neck).

Without a monitor arm or riser, you are forced to choose between proper neck posture and proper typing posture. You cannot have both on a standard laptop. This calculator provides the exact “Z-Axis” elevation required for your display to decouple head position from hand position.

Setup FAQ

Why does the calculator suggest a ‘low’ desk height?

Most commercial desks are 29-30 inches high, which is suitable for a 6’2″ person writing with a pen. For typing, you need the keyboard much lower (closer to lap level) to prevent shoulder shrugging. A keyboard tray is often the cheapest fix.

How do dual monitors affect this?

If you use dual monitors equally (50/50 split), the gap between them should be centered directly in front of you. If you have a Primary/Secondary setup (80/20), the primary monitor must be directly centered, with the secondary angled off to the side to minimize neck torsion.
