Methodology & data
Rule checks compare your inputs against published manufacturer spec ranges for the four common arm tiers (Ergotron LX/HX, Fully Jarvis/Cooper, Herman Miller Flo, Humanscale M2.1). Weight is normalised to pounds (1 kg = 2.20462 lb).
VESA, clamp-depth and panel-size checks are hard pass/fail. A weight within 90% of a tier's maximum is flagged CAUTION because gas-spring tension calibration drifts near the ceiling. Curved and ultrawide panels add a moment-arm caution unless the tier is rated for them.
This is a planning aid, not a substitute for the manufacturer's own load chart for your exact model.
