What is the Desk Height Calculator?
The Desk Height Calculator estimates the ideal working surface height for your desk based on your body height. A correct desk height keeps your elbows roughly at a 90° angle, your shoulders relaxed, and your wrists straight — reducing the strain that leads to neck, back, and wrist discomfort during long hours of work.
How to use it
Enter your height in centimeters and choose whether you are setting up a seated desk or a standing desk. The calculator returns the recommended desk surface height in both centimeters and inches. Treat the result as a starting point and fine-tune by a few centimeters until your forearms rest comfortably parallel to the floor.
The formula explained
The estimate uses a simple proportional model. For a seated desk the surface should sit near 26% of your body height, while a standing desk's elbow-level surface sits near 62% of your body height:
Seated: $$\text{Desk Height (cm)} = \text{Height (cm)} \times 0.26$$Standing: $$\text{Desk Height (cm)} = \text{Height (cm)} \times 0.62$$
Worked example
Suppose you are 175 cm tall and using a seated desk. The recommended height is $$175 \times 0.26 = 45.5 \text{ cm}.$$ Converting to inches: \(45.5 \div 2.54 \approx 17.9\) in. For a standing setup the same person would aim for \(175 \times 0.62 = 108.5\) cm (about 42.7 in) at the work surface.
FAQ
Should monitors be at desk height? No — the top of your monitor should be roughly at eye level, which is usually well above the desk surface. Use a stand or arm if needed.
Is this a substitute for professional advice? It is a quick guideline. If you have existing pain or specialized needs, consult an ergonomics professional.
Does chair height matter for a seated desk? Yes. Set your chair so your feet are flat and thighs parallel to the floor first, then adjust the desk to elbow height.
