In the calculation of the pelvic index, which line serves as the denominator?

Explanation:
In this calculation, the pelvic index is a width-to-height ratio, so the dimension used to normalize the value is the height. The denominator is the vertical distance, which corresponds to the line labeled as Y in the diagram. The horizontal distance (the line representing width) would be the numerator, not the denominator, so it isn’t used as the base of the ratio. Using both or neither would not reflect a single baseline measurement.
