Work out workstation height instantly with clear inputs, formula shown and shareable results.
Work surface height is set relative to elbow height, not to a standard dimension. Precision work sits 5 to 15 cm above the elbow so the eyes are close enough without stooping; light assembly sits just below; heavy work sits 15 to 40 cm below so the arms can use body weight. The surface is then dropped by the height of the workpiece so the working point lands correctly.
Surface height
Surface = elbow height + task adjustment - workpiece height
Preliminary estimate only. Workstation design should be assessed by a competent ergonomist against anthropometric data for the actual user population.
Surface = elbow height + task adjustment - workpiece height. Work surface height is set relative to elbow height, not to a standard dimension.
Set it for the tallest and provide platforms for shorter workers, or use an adjustable bench. Setting it for the average leaves everyone uncomfortable.
This calculator takes 3 inputs: Standing elbow height, Task type, Height of the workpiece. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
