Use the calculated heights as starting ranges

The calculator uses stature-based relationships to estimate chair, keyboard/work-surface, and monitor-top ranges for seated and standing work. These are not prescribed medical dimensions. Body proportions, footwear, chair design, keyboard thickness, task type, screen size, vision needs, and available adjustment can all change the practical setting.

Fit the workstation to neutral posture

Adjust the keyboard and mouse so the shoulders stay relaxed, elbows remain close to the body, forearms and wrists are approximately straight, and elbows are near keyboard height. While seated, support the feet on the floor or a footrest and keep adequate thigh and leg clearance. A keyboard tray or chair adjustment may be needed when a fixed desk cannot reach the target posture.

Check the monitor separately

Place the monitor directly in front of the user. The top of the screen is generally at or slightly below eye level, with a comfortable downward viewing angle. Monitor distance, text size, bifocals, multiple displays, and laptop use can require a lower or otherwise different position, so confirm that the head and neck remain balanced rather than relying only on the calculated monitor range.

Frequently asked questions

Common questions about seated and standing desk height, keyboard placement, monitor position, and neutral posture.

Is the calculated desk height a final ergonomic setting?

No. It is a stature-based starting range. Adjust the chair, keyboard, mouse, work surface, foot support, and monitor until the user can maintain a comfortable neutral posture without raised shoulders, bent wrists, reaching, or neck tilt.

Where should the keyboard and mouse be positioned?

Keep them directly in front and close enough that the elbows remain near the torso. Keyboard height should be near elbow height, with relaxed shoulders and wrists approximately straight and in line with the forearms.

What if a fixed desk is too high?

Raising the chair may bring the elbows to keyboard height, but the feet must then be supported and there must be adequate thigh clearance. A keyboard tray or a different adjustable work surface may be needed.

How high should the monitor be?

A common starting point places the top of the screen at or slightly below eye level, directly in front of the user. Bifocals, large or multiple displays, laptop use, and text size can require a lower or different position.

Why does the calculator show a range instead of one height?

People with the same stature can have different limb and torso proportions, equipment, tasks, and preferred postures. A range supports adjustment and posture checking better than a false single ideal number.

Should I sit or stand all day once the desk is adjusted?

No single posture should be held for long periods. Change position, make small adjustments, and take movement or recovery breaks during the day.
