The length of the pitch man is 60 to 66 cm, on average - 63 cm Comfortable ladder corresponds to the formula: 2 step height + depth level = 63±3 cm. The most convenient tilt ladder - from 30° to 40°. Depth staircase steps must meet size 45 shoes - no less than 28-30 cm Lack of depth can compensate for the projection step.
