Inlet contraction exists if the anteroposterior diameter is 10 cm or less or if the transverse diameter is 11.5 cm or less. Midpelvic contraction exists if the sum of the measurements in centimeters of the interspinous diameter (normally 10.5 cm) and the posterior sagittal diameter (normally 5 cm) is 13.5 cm or less.
