Use this free desk height calculator to find the ideal seated and standing desk height, chair seat height, and monitor position for your body. Enter your height and we’ll estimate ergonomic starting points so your elbows, wrists, and eyes stay in a neutral, comfortable posture all day.
Monitor top ≈ at your eye level; screen center ~h×0.43. Starting points — adjust so elbows & wrists are neutral and the top of the screen is at/below eye level.
How to use this desk height calculator
Enter your full standing height and pick your unit (cm or inches). The tool applies anthropometric ratios to estimate your ideal seated desk height (where your keyboard sits with elbows at roughly 90°), your standing desk height (about elbow height when standing), your chair seat height, and the monitor top height so the top of your screen lands at or just below eye level. Every result is shown in both centimeters and inches so you can dial in any adjustable desk or chair.
Why ergonomic desk and monitor height matters
A desk that's too high forces your shoulders up and strains your neck; one that's too low rounds your back and cramps your wrists. The same applies to your monitor: looking down at a low screen pulls your head forward, while a screen that's too high tires your eyes. Use these figures as a tuned starting point, then fine-tune by feel — your forearms should rest level, your wrists should stay straight, and your gaze should fall comfortably on the top third of the screen. Small changes of 1–2 cm can make a big difference over a full workday.
