How the calculators work

The math, briefly.

Every number we output is grounded in a published reference. We list them here so you can audit - or correct - us.

No. 01
Seated geometry

Desk and chair heights come from Hokwerda et al.'s seated anthropometric percentiles, adjusted for shoe height and a 100°-110° hip angle target.
No. 02
Monitor distance

Eye-to-screen distance follows the AOA arm's-length rule (50-70 cm), tuned by screen size and pixel density.
No. 03
Chair fit

Seat-pan depth, lumbar height, and armrest range filtered against our 240-product database. Updated quarterly.
No. 04
Budget allocation

Weighted toward chair (45-55%) for desk-bound work, monitor (15-20%) for visual workers, lighting (5-10%) baseline.
