Vertical torso measurements, which include the back (neck-waist) length, the shoulder-waist length (not the same as the back length, due to the slope of the shoulder), the bust-shoulder length, the bust-waist length, and the two hip-waist lengths.
Instead, the label should show the range of body dimensions from half the step size below to half the step size above the design size (e.g., "height: 172–180 cm."). For heights, for example, the standard recommends generally to use the following design dimensions, with a step size of 8 cm:
