Ergonomic Chair & Desk Setup Calculators
Free, practical tools for dialing in a healthy seating setup — size your chair and desk to your body, position your monitor, check whether your chair can take your weight, balance sitting and standing through the day, and confirm your posture holds up.
Seat Height Calculator
Find your ideal chair seat height from your body height, so your feet rest flat and your thighs stay level.
Desk Height Calculator
Get the right sitting or standing desk height for your stature, keeping elbows near 90° and shoulders relaxed.
Monitor Distance Calculator
Work out how far back and how high your monitor should sit, from your height and screen size.
Chair Weight Capacity Checker
Find the minimum capacity to look for on a chair's label, with a margin rounded up, and check your own chair's label against it.
Sit-Stand Calculator
Plan a healthy sit-stand balance across the working day — how many minutes to stand each hour.
Posture Angle Checker
Check your seated posture against the neutral 90-90-90 rule for hips, knees, and elbows.
