Dürer defined the child's overall height as 1 unit so that the image could easily be rescaled to any size. Each number on the drawing indicates a body dimension as a fraction of that unit. On the lateral view of the arm, for example, the width at the shoulder is one tenth of the child's total height, whereas at the elbow it is one sixteenth and at the wrist, one twenty-third.
