Desk Height Calculator

What is an Ergonomic Desk Height?

An ergonomic desk height is the optimal height for your desk that allows you to maintain a neutral, comfortable posture while working, whether you are sitting or standing. A properly adjusted desk can significantly reduce physical strain on your back, neck, shoulders, and wrists, leading to increased comfort, productivity, and long-term health benefits. The Desk Height Calculator is a tool designed to provide personalized recommendations for both sitting and standing desk heights based on your individual body height, helping you create a healthier and more efficient workspace.

How to Use the Desk Height Calculator

Finding your ideal desk height is simple with this calculator. Just follow these easy steps:

1. Enter Your Height: Input your height into the designated field. You can stand against a wall and have someone mark the top of your head for an accurate measurement.
2. Select Your Unit of Measurement: Choose whether you are entering your height in centimeters (cm) or inches. The calculator will use this to perform the correct conversion.
3. Calculate: Click the "Calculate Desk Height" button. The calculator will instantly display the recommended heights for both a standard sitting desk and a standing desk. The results are shown in both inches and centimeters for your convenience.

The Ergonomic Formulas Used

The calculator uses established ergonomic principles to estimate the ideal desk heights. While individual preferences may vary slightly, these formulas provide an excellent starting point for a neutral posture.

The formulas are:

Sitting Desk Height (inches) = (Your Height in inches * 0.25) + 18.5

Standing Desk Height (inches) = (Your Height in inches * 0.45) + 18

For a sitting position, your elbows should be at or slightly above the desk surface, forming roughly a 90-degree angle. For a standing position, the same principle applies. Your feet should be flat on the floor, and your wrists should be straight when typing.

Practical Example

Let's see how the calculator works for a person who is 5 feet 9 inches tall.

• First, we convert the height to a single unit. 5 feet = 60 inches. So, the total height is 60 + 9 = 69 inches.
• Sitting Desk Height Calculation: (69 * 0.25) + 18.5 = 17.25 + 18.5 = 35.75 inches.
• Standing Desk Height Calculation: (69 * 0.45) + 18 = 31.05 + 18 = 49.05 inches.

The calculator would recommend a sitting desk height of approximately 35.8 inches (90.9 cm) and a standing desk height of about 49.1 inches (124.7 cm). The user can then adjust their office chair and desk to match these ergonomic recommendations.

Frequently Asked Questions (FAQ)

Are these heights guaranteed to be perfect for me?

This calculator provides a scientifically-backed starting point. The ideal height can also be influenced by your chair height, torso vs. leg length ratio, and personal comfort. Use these results as a baseline and fine-tune by a half-inch up or down until you feel most comfortable.

What if I use a keyboard tray?

If you use an under-desk keyboard tray, the height of the tray should be at your calculated "desk height," not the desk surface itself. Your monitor should then be raised so the top is at or slightly below eye level.

How does chair height factor in?

Your chair should be adjusted so your feet are flat on the floor and your knees are at a 90-degree angle. After setting your chair height, you then adjust your desk height to match your elbow level.
