Comprehensive Calculator Guide
This calculator suggests, from your height, a chair seat height, a sitting desk range and a standing desk height. At 175 cm: a chair of about 44 cm, a sitting desk of 66–73 cm and a standing desk of about 110 cm. The aim is elbows near a right angle, feet flat and a straight neck, easing back, neck and wrist strain.
Where the figures come from
Average body proportions: standing elbow height is about 63% of height and the back-of-knee height (hence chair height) about a quarter. The sitting desk range comes from formulas relating it to height, since it also depends on the chair.
People’s limbs differ, so treat the figures as a starting point and adjust until elbows sit at 90–110°, feet are flat and the screen top is at or just below eye level. Standard desks are 72–76 cm; if your range is lower, raise the chair and use a footrest.
How to Use
- Enter your height in your usual work shoes.
- Change the unit if you like.
- Press “Work out the heights” to see chair, sitting desk and standing desk heights.
Formula Used
Chair ≈ 0.25 × height | Sitting desk ≈ 0.474 × height − 17 to 0.554 × height − 24 cm | Standing desk ≈ 0.63 × height
Practical Examples
- Example 1
- 175 cm: chair 44 cm, sitting desk 66–73 cm, standing desk 110 cm.
- Example 2
- 160 cm: chair 40 cm, sitting desk 59–65 cm, standing desk 101 cm.
Important Tips
- Alternate sitting and standing every 30–60 minutes.
Common Mistakes to Avoid
- Raising the chair so far your feet dangle without a footrest.
