The carpenter is a scale based on body proportions; the tilt is calculated on the model with stiff knees—in reality, you’re more likely to bend your knees all the way down. Red indicates 60° and above, the angle that ISO 11226 no longer accepts for torso tilt.

A rule of thumb from ergonomics according to Grandjean (not a measured value): light work should be performed 10 to 15 cm below the elbow; work requiring downward force should be performed 15 to 40 cm below the elbow. The specific distance we choose for each task is based on our own judgment.
