Standing Desk Height + Sit/Stand Planner
Part 1: your height and heel give your ideal standing desk height (elbows ~90–100°) and seated height, checked against your desk's travel range. Part 2: pick a ramp goal and work hours to generate a daily sit/stand schedule you can copy.

Methodology & sources
Standing desk height. The keyboard surface should sit at standing elbow height with the elbows at ~90–100°. Standing elbow height ≈ 0.630 × stature (a standard anthropometric ratio; ISO/NASA anthropometric tables put elbow height at 0.62–0.63 of stature). We add a small allowance because a relaxed shoulder and a thin keyboard put the working surface marginally above bare elbow height, then add your heel height.
Seated desk height. With the chair set so thighs are horizontal and feet supported, the seated working surface sits at seated elbow height. We estimate seated elbow-rest height ≈ 0.145 × stature above the seat and a popliteal (seat) height ≈ 0.25 × stature, summing to the floor-referenced desk height — consistent with BIFMA G1 fixed-desk guidance (≈ 71–74 cm for average adults).
Sit/stand schedule. Ramps follow the Buckley et al. 2015 occupational consensus (accumulate ~2h then ~4h standing/light activity per working day) and Cornell ergonomics' advice to alternate roughly every 30 minutes. Educational only — not medical advice.
