5 cm

8 cm

10 cm

The cervix needs to dilate to 10 cm to allow for the passage of an infant during delivery. This measurement is critical because full cervical dilation is the point at which the cervix is completely open and the fetus can move down the birth canal. In the process of labor, the cervix undergoes significant changes, progressing from a closed state to 10 cm of dilation. Dilation beyond this point ensures that there is adequate space for the baby's head to navigate through the birth canal without restriction, which is essential for a safe delivery. Hence, 10 cm is the standard measurement recognized in obstetrical practice for full dilation.
