Height & Position
Tip: If unsure, stand straight, heels together, look ahead, and have a friend measure from floor to crown.
Recommended ranges
Thighs and feet parallel to the floor (knee angle 90–110°).
Wrists straight, elbows ~90–110°. For standing, set desk at/just below elbow height.
Eye line hits the top third of the screen; tilt ~10–20°.
Quick summary
Step-by-step derivation
Given: Stature (inches).
Desk (sitting) range is computed from empirical ergonomic regressions:
- Min = 0.4739 × height − 6.678
- Max = 0.5538 × height − 9.4270
Chair (sitting) approximates knee/popliteal height: ~24.6%–26.9% × height.
Monitor (sitting) puts top-third near eye line: ~69%–72% × height.
Desk (standing) centers on elbow height; ergonomic rule-of-thumb:
- Range ≈ 60%–65% × height
Monitor (standing) top near eye height: ~93.5%–95% × height.
Reference guidance
| Guideline | Why it matters |
|---|---|
| Keyboard & mouse at elbow height; elbows ~90–110° | Neutral shoulders/wrists; reduces strain. |
| Top of monitor at or slightly below eye level; tilt 10–20° | Keeps neck neutral; reduces glare. |
| Chair so thighs/feet are parallel to floor | Maintains 90–110° knee angle and circulation. |
