How to Calculate Desk Size Manually
Step 1: Calculate Desk Height
This ensures the desk surface aligns with elbow height for neutral posture.
User Height = 173 cm
173 × 0.44 = 76.1 cm
(≈ 30 in)
Step 2: Calculate Desk Width
Each monitor requires additional horizontal space for comfortable use.
Monitors = 2
36 + (2 × 12) = 60 in
Step 3: Calculate Desk Depth
Ensures proper viewing distance and space for keyboard and accessories.
Monitor Size = 24 in
20 + (24 × 0.5) = 32
in
✅ Final Manual Result
60″ W × 32″ D × 30″ H
Suitable for dual monitors and ergonomic posture.

Desk Design & Ergonomic Tips
- Leave 36 inches clearance behind the chair for movement.
- Maintain 20–30 inches viewing distance from monitors to reduce eye strain.
- Use ≥ 30 inch depth if you have multiple screens to keep them at a proper distance.
- Choose adjustable desks for shared spaces to accommodate different heights.
- Keep your keyboard tray 2–3 inches lower than the desk surface for relaxed shoulders.
