Standing Desk Ergonomic Height Calculator
Why a Single “Standard” Desk Height Doesn’t Work for Most People
Most fixed-height desks are built around a 28- to 30-inch height, a number that happens to suit someone around 5’9″ reasonably well and fits almost nobody else particularly. One of the more direct causes of wrist and shoulder strain during a full day of use is elbow angle, which is determined by desk height when typing. A desk that is too high forces your shoulders to shrug to keep your hands at the surface, and a desk that is too low forces your wrists to bend upward to reach the keyboard. These effects compound over hours in ways that don’t seem like much at first but add up over months.
This calculator estimates both a sitting and standing desk height based on your actual height, using standard anthropometric ratios rather than a single one-size number. It also outputs a monitor top-of-screen height, since desk height and monitor height are two separate ergonomic decisions that people often solve for one and ignore the other.
Reading The Results And Adjusting From Here
For either desk height, try to keep your elbows at about a 90- to 100-degree angle, with your forearms just below or level with the desk. If your desk is more than an inch higher or lower than the calculator suggests, make small changes rather than leaving it as is.
Frequently Asked Questions
What is the correct desk height for my height?
Standing desk height is approximately two-thirds of your height minus two inches, and sitting desk height is approximately one-third of your height plus four inches. Use these as a starting point for fine-tuning because they are population averages rather than customized measurements.
What elbow angle is ergonomically correct at a desk?
When typing, most ergonomic recommendations aim for an elbow angle between 90 and 100 degrees, with forearms roughly level with the desk surface. This holds for both standing and sitting desk heights, not just one.
How high should my monitor be on a standing desk?
The general rule is that the top of the screen is at or slightly below eye level, so your eyes look down a few degrees rather than straight ahead or upward at the screen. This measurement is from the floor to the top of the screen, regardless of the height of your desk or monitor stand.
Is a sit-stand desk actually better for posture than a fixed-height desk?
The primary ergonomic argument for a sit-stand desk is that alternating between sitting and standing throughout the day lessens the sustained strain of maintaining one posture for hours. Nevertheless, the proper height at either position is more important than the position you are in at any given time.
